Who invented Skype

Before hacking the bot or how to deceive the bot, it is worth understanding what "bot" is. In simple language, the bot is an assistant program who will unquestioning to fulfill all the teams given to him in Telegram. For example, it may in the morning to offer a selection of interesting news user, and in the evening you recommend the film.

To perform data and similar functions, these small helpers use the same interfaces as ordinary users.

"Language" of bots

Before you start hacking a bot, first need to know what the client code looks like and what language it uses.

You might think that C # (si Sharpe) was used to write a program, which is a very popular and modern programming language. He received popularity due to the autonomy of the program, a large functional and a small number of RAM.

But this is not so, for the computer version, C ++ was used, for Android - Java. Also for bots acceptable languages \u200b\u200bare:

• HTML;
• Python;
• Javascript.

Payment in Telegram

In financial operations, telegrams are an intermediary. The client sends the necessary data by its credit card specifically to the payment system. Then answer the payment system and all necessary information The bot developer is transmitted, after it can process and complete the operation.

Here the bots greatly simplify buy-selling for both sides. Buyer can from any corner of the world and at any time of the day to purchase some product from the seller.And for the seller carries out sales, since he does not need to constantly sit in the application and wait for buyers.

However, any controversial payments are responsible for developers of bots and providers of payment systems, as telegrams do not participate directly in financial transactions.

Hack a bot

Most programs that promise to hack bot act on the same system:

1. Download program.
2. Run the downloaded application.
3. Act.

In most cases, the site that offers and assures that "crack" can easily bypass the telegram security system and deceive the bot, is malicious, and download, and even more so run the downloaded program is categorically impossible for the safety of its device.

Theoretically, such a program can be created completely, having studied the encryption protocol and spending a lot of time writing such an algorithm. However, it is impossible to find such a program in open forums.

Telegram Sender.

In fact, this program is an ordinary spammer. A group of developers found a small way to get around protection, and created its program. The program works easily:

1. Write some text.
2. Payment.
3. Get the result.

Scripts

Scripts in the telegram application serve to automate any action or creating a bot. You can download them easily from the official site of developers.

Also using scripts can also be for cheating bot in telegrams. After all, the bot is a program working on a certain specified algorithm.So the hacker simply simply reproduce some request algorithms, namely certain plugins that generate specially questions in such a way that the bot allows you to purchase a certain item for free.

It is difficult to imagine the modern world without Skype, but few people know when he appeared. This service allows you to exchange not only text messages, but to perform voice and video calls. 2003 was marked by innovations, which forever changed the digital world. From the moment of occurrence there was a lot of gradual changes that improve the interface, and therefore a user with basic skills may quickly get comfortable.

Historical excursion

Skype has paid and free versionsTherefore, everyone will be able to choose the appropriate option. The developers were able to integrate Facebook with a messenger, and it allowed to save more time. It is difficult to come up with a program that could enjoy so great popularity, and therefore the history of creation is important.

First stage

As soon as work begins in the messenger, users often appear the desire to get answers to simple questions: "In which year and where did Skype come up with?". Estonia - a country where worked:

• Ahty Heinla;
• Come caasesal;
• Yan Tallinn.

They were able to create a KAZAA file sharing, which is very popular at one time. Scandinavians were able to be the first not only to invent, but also embody the idea of \u200b\u200ba program that allows to maintain constant contact with relatives and close, where they were not. Invent Skype, in the form in which he became known to the general public, was able to Janus Friesia and Niklas Zenstster.

Then they had a simple, but a brilliant idea - to provide each user who has permanent access to the Internet, the ability to unlimited communication. The date of the first official release is August 29, 2003. The country of residence no longer had a fundamental importance, since it was possible to contact someone in just a few seconds and absolutely free. At some point, the program has become not just in demand, but also one of the irreplaceable.

First profit

Not knowing who invented Skype, it is difficult to argue about their true intentions of developers. The bright and memorable appearance of the messenger did not give any profits, and after all, the efforts should not remain in vain. When users could have the opportunity to exercise direct calls to ordinary numbers, using reduced prices, the first profits did not make long wait. Belong to the number of profitable projects - the task is not the lungs, but Skype managed to deserve to withstand competition. Wikipedia writes that after 2 years, the company's capitalization amounted to about $ 35 million per quarter, and many interesting events begins with this.

In 2005 the largest auctioneBay. became to belong a messenger. It was hard to predict the final result from such a transaction, but everything was most benefited. The year 2006 was marked by the growth of the company's revenue, which in monetary terms amounted to about 195 million dollars. Who owns the idea of \u200b\u200btotal improvements in the program - mystery, but you can talk about impeccable strategy and plan. Ebay was able to withdraw Skype to a new level, constantly involving active users.

A short-term coma in the development of the company comes in November 2009, when eBay decides to sell a controlling stake (70% for $ 2.5 billion). Noteworthy is the fact that the initial creators received places in the Board and 14% of the shares. They did not qualify more for more and withdrew legal responsibility.

Together with Microsoft.

In 2011.yearMicrosoft decided to make a valuable acquisition by exchanged $ 8.5 billion on the company's controlling stakeSkype.. This deal was unprecedented by the number of money spent. The board of the company hatched its plans, and therefore they painlessly broke up with such a sum. Messenger is available in almost all countries, and even Russia, possessing such a big length, does not experience problems.

Innovations

Today Skype can be downloaded for a variety of devices and platforms starting from Windows and up to Linux. New markets continue to expand, and this requires a certain mobility of developers.

The messenger was able to surpass the initial ideas of the creators, since the initial scheme was improved and improved. Consumers were able not only to make calls to different countries, but also to conduct group sessions.

Thanks Microsoft Program It was possible to reveal its true potential and turn off the limits of simple calls. Each user is provided with a unique opportunity to exchange information and file chat files. The creators, for sure, are satisfied with the results of their work.

Call via the Internet for a regular cellular or city phone? Easily. Contact another user in the network by setting direct audiovisual contact? Even easier! VoIP and softfones are rapidly conquering the markets of the whole world, and on the edge of this "attack" there is a program whose name is well familiar to everyone - Skype. Here we'll talk about her today.

Before Skype, or a guide

Many of the fictions of the XIX-XX centuries predicted that sooner or later, humanity invented the sort of video phone, thanks to which the interlocutor could not only hear, but also to see. Some, especially gifted personalities (Tesla, for example) spoke to this while at a time and the usual phone was in the wonder.

In fact, humanity coped with the invention of such a thing rather sooner than later. Sudi himself: another 15 years ago it was difficult to think about that quite soon at our disposal will appear compact and powerful cell PhonesWith which you can easily make a video call to anywhere in the world (about the fact that you can also simply go online, listen to music, read, watch movies and so on, and there is nothing to say).

It is worth noting that attempts of the invention of the video font as an independent device is a topic worthy of a separate story. For example, in 1964, AT & T managed to establish in New York, Washington and Chicago's first buddies of public video telephones. The machines that worn by the name Picturephone Mod I were also with POMPA installed at headquarters of large companies. It was planned that innovation would have a loud success, and continue to come to coming. In the device, by the way, 3 pairs of telephone wires were used: one for the transmission of sound and two (with a 1 MHz bandwidth) for video transmission in each direction. The image was updated once in 2 seconds. For switching video used additional PBX. But the public did not appreciate all these efforts - the call from New York to Washington cost $ 16 in 3 minutes, and in Chicago - $ 27, which scared even the most revealed gickers of that time. As a result, the booths were dismantled in 1968.

However, we were distracted. Our today's story will do not at all about video payphones, but about the idea of \u200b\u200bvoice and images on the network, which appeared almost earlier than the inventive of the computer networks themselves.

No matter how paradoxically sounds, until a certain period of time, telephone networks and data networks existed independently of each other. The fact is that the technique and channels of those years simply did not cope simultaneously with the other. Scientists beat over the resolution of this problem since the 60s, but the first notable moves were outlined only in the 80s, when ISDN was created - a network that supported the service for transmitting speech, data, video and text. But then there were only the first steps, and the real results and the actual "birthday" Voice Over IP (VoIP) and video conferencing were already in the 90s.
The first swallow, which broke the Dam Network Silence, was the program Phone, created by Israelis from Vocaltec. Internet Phone was released in early 1995 and, in fact, was a banal IM + SoftFon, with which it was possible to call the other PC. But what seems to be banal now, then caused emotions like "Omigod, IT" s magic !! 11 ". And this is despite the fact that this miracle worked in half duplex mode, that is, unilaterally, as when talking on the radio ( Which is not surprising - the idea of \u200b\u200bthe program, the founders of Vocaltec have learned during the service in the army, looking at the batch voice).

Neither the above, nor the fact that the quality of communication usually left much to be desired, could not stand on the way at progress - in a few weeks the Internet Phone downloaded thousands of people and immediately began to actively use it. This was the disadvantaged - it became obvious that the interest of the public was great, and the prospects for Internet telephony are huge. The market was immediately flooded by all sorts of clones of the Israeli program, and by the end of 1995, Softtina DigiPhone appeared on sale, which made it possible to listen and speak at the same time.

In the frame of the software for transferring video over the network of the case, meanwhile, too, were not bad. At the beginning of the same 90s, the craftsmen from Cornell University wrote a CU-SEEME program, originally intended for Mac "OV, and then released and under Windows. By the way, it is with the help of Cu-Seeeme in 1994 during the flight of the shuttle Endeavor NASA Transmitted to Earth its image.

Interest in VoIP technology, that is, to the transmission of a speech signal via the Internet or other IP networks, increased quickly, and already in 1996 issues of standardization and reality of standards. International Telecommunication Union is an international organization that defines recommendations in the field of telecommunications and radio, as well as regulatory issues of international use of radio frequencies, adopted recommendations on the standard H.323, which was based on almost 50 other standards. Thus, the first standard for multimedia communications was adopted using packet-oriented networks that do not guarantee the quality of service. At the same time, the open international community of designers, scientists, network operators and Internet Engineering Task Force (IETF), which is engaged in the development of protocols and Internet architectures, has developed the Realtime Transport Protocol (RTP) protocol, which has been used in H.323.

Further development VoIP spacing as follows:

• 1996 was also noted by the conclusion of the agreement between Vocaltec and the Giant Dialogic. The goal of their joint project was to create the first specialized telephone gateway for IP telephony, which received the name Vocaltec Telephon Gateway (VTG).
• 1997 gave the world the opportunity to call not only with a PC on a PC, but also from a PC to the phone and vice versa, as well as from the phone to the phone.
• 1999 was marked by the first specification of the SIP Open Standard (Session Initiation Protocols), the development of which since 1996 was engaged in the guys from IETF, and which will be discussed below. H.323 has a competitor who will show time, will very quickly deal with his predecessor.

That's so imperceptibly, it came to the new millennium, which means that the creation of Skype.

Skype.

Skype belongs to Peru of European prieffs, namely the Estonians of Ahti Heinla (Ahti Heinla), to Priit Kasesalu and Jan Tallinn (Jaan Tallinn). These names may surprise someone, because in recent years, the creators of Skype are more often called very other people - Dane Janus Friisa (Janus Friis) and Swede Niklas Zennstrom (Niklas Zennstrom). The thing is that the first and second are true.
It is possible that the names of the three Estonian developers, not only caused surprise, but also seemed to some readers vaguely familiar. If it seemed, we hurry to delight - you have excellent memory. The fact is that in the early 2000s, these guys were engaged in the development of an unforgettable file sharing P2P network of KAZAA, thanks to which the fame was revealed. Work on Skype, which gentlemen IT journalists unfairly put in the merit of Friis and Zennstrem, respectively, was after.

"Who is such Zennstrem and Friesis?" - You ask you. Of course, they also appeared in this story. It is no coincidence that this couple had the most direct attitude towards the development and development of both projects (both Kazaa and Skype), and some of their "feats" literally eclipsed the rest of the team. Nevertheless, calling them the "creators of Skype" - a strong exaggeration, since, first of all, these two are businessmen and investors, but not developers. More about Frisé, Zennstrom and their role in Skype, we will tell you separately below, but for now let's go back to the program itself.

Active work on Skype was launched in 2002 after solid investments by Draper Investment Company, and in the light of Softina came out pretty quickly: the domain names of Skype.com and Skype.net were registered in April, and the first beta release of the public program saw already in August 2003. By the way, Randomny interesting fact - During the development of the program, I wore Skyper name (reduction from Sky Peer-to-Peer), and only closer to the completion of the work was renamed Skype, because the Skyper's domain name was already occupied.

So, what distinguished Skype from a variety of other similar programs, which were released a little more than before the fig? Unlike other software designed for IP telephony, Skype used to this day uses P2P architecture to work, which is not at all surprising if you remember the track record of its creators. In fact, this is one of its main advantages: all voice traffic goes through the network nodes that users themselves are (and the more users use the system, the better it works). Skype can routing calls through computers of other users, which allows users to connect to each other for NAT or firewall (creating an increased load on the remaining channels).

By the time of the Skype exit to the IP telephony market, almost all of this market was occupied by software and hardware, based on the SIP standard, which time came to tell more.

Unlike the Skype classified protocol, SIP is fully opened for developers, well thought out and easy for hardware implementation. For sample for SIP, the SIP HTTP message protocol was taken, as well as queries http.are transmitted via the Internet in text form, and their formats partially coincide. This will noticeably simplifies the development and debugging of programs supporting SIP, and, quite likely contributed to the growth of its popularity. As well as Skype, SIP does not have a centralized server - a lot of servers; In fact, anyone can acquire this, and they all interact with each other. The task of the protocol includes only the installation and negotiation of communication, while it is not at all necessary that this relationship is a voice - this can be any other data flow (video, multimedia, interactive service).

SIP is focused on working in local networks and on good Internet channels.

Skype is the complete opposite of SIP, although some data indicate that the Skype protocol is based on the modified SIP. Be that as it may, the differences are more than enough: Skype - the protocol is closed, and by virtue of its P2P structure uses forced encryption (data is encrypted using AES-256, to transfer the key of which, in turn, use 1024-bit RSA key . Open users are certified by the Skype central server when logging in using 1536- or 2048-bit RSA certificates), and it is much better than SIP adapted to extreme conditions. The phrase "I am in the door, and it in the window" most accurately reflects the Skype behavior scheme - close it the usual range of ports of the UDP protocol ports, and it switches to free TCP ports, and if it doesn't fit at all, Skype is always ready to use HTTP proxies. Some experts argue that the only way to completely block Skype is to analyze the content of all packages that Skype, do not forget, encrypts. More simple methods The program is bypass.

All years listed for many years seriously strains the intelligence agencies of almost all countries of the world - how so that it is impossible to intercept and decipher, it is definitely disorder! However, Switzerland, Australia, Austria, Germany and Russia have already hinted that they still have solutions for listening to Skype in Arsenal.

Criticize Skype and many security experts, and even hackers. Back in 2007 in a hundredth room] [Chris Kaspersky dedicated to this issue the unfolded article entitled "Skype: Hidden Threat." In the article, Chris writes the following: "Skype is a black box with a multi-level encryption system that is stocked with anti-store receptions of the executable file reading from a computer confidential information and broadcasting it on the closed protocol. The latter bypassing firewalls and sternly masks their traffic, preventing it from blocking. All this turns Skype in the perfect carrier of viruses, worms and drones, creating their own distributed networks inside the Skype network. "

But it was not possible to conquer the wide audience of Skype, but at the expense of two very important things: simplicity and excellent sound quality.

Starting from the very first version, the autumn of 2003, Skype supported 10 languages \u200b\u200band had the most simple interface, unlike other IM, initially sharpened precisely under voice communication. The fact that the entire procedure for installing the program and registration of the new user was at times easier than competitors. As for the codecs, Skype uses SVOPC (16 kHz), AMR-WB (16 kHz), G.729 (8 kHz) and G.711 (ILBC and ISAC also previously used), which is also sufficient compound speed (30-60 kbps / s) allows you to get a sound comparable in quality with a regular telephone connection.

Immediately taking from a room in a quarry in 2003, Skype did not stop at a minute in development. With each new version More and more new features and "amenities" appeared. List all these answering machines, online numbers, conferences, services to send SMS and so on does not make sense, since the article still is called not "Skype services for teapots" :). Instead, I would like to note the other - the company confidently developed, despite even the fact that in 2005 Friesis and Zennstrem sold their brainchild that had already gained enormous popularity (74.7 million accounts and an average of 10.8 million users on the network), Ebay for a round sum of several billion dead presidents. The fact that on the development of Skype it was reflected in no worse, the figures and facts are clearly said:

• Today, more than 560 million accounts are already reading in Skype;
• There are Skype versions for almost all the platforms known to humanity, including mobile;
• The company presents the whole range of VoIP services;
• Skype releases and sells various gadgets from headsets and webcams to full-fledged Skype - phones that can work with both a regular telephone network and with Skype.

We divided the orange, or patent trolling

Now, after illumination of all sorts of technological aspects of Skype, you can talk about more funny things - we have the most real "scandals, intrigues, investigations" for dessert.

As it was promised, back to the personalities of Niklas Zennstrem and Janus Freisa and consider them closer. Zennstrem is a graduate of the Uppsaal University, the owner of a bachelor's degree in business administration and master's physics. Frisis, on the contrary, can not boast a "tower", because at one time I threw school and went to work in the technical support of the local provider.
It so happened that at the very beginning of the life and career path, these two got a job in the Swedish telecommunications company Tele2, where in 1996, fate in 1996.

Having worked side by side for a few years, Zennstrem and Fris are so rushed, which in 2000 decided to quit and start their own business, which was the File Bedding Network Kazaa. In fact, for its development, Friis and the Zennstrem moved to Amsterdam, hired programmers team, and would prefer to remain in senior positions.

However, the Casus came out with Kazas - did not have time for the brainchild of Frisis and Zenstremka to gain momentum as active persecution began on the peering networks. Just then closed the legendary napster, and the seat is not known, there is no empty - all illegal content of drowshes into other networks, one of which was Kazaa. The copies immediately began to deposit of our Mount-businessmen, wanting to drown them in litigations, and such a state of affairs of the new starts had to do not like it at all. Zennstrem and Frisi were forced to classify the findings of the company's offices and in the literal sense to hit the run, hiding from the agenda that looked from the horns of abundance.

When it became completely clear that the saying "Time heals" on this situation It does not apply, and it only gets worse, from Kazaa was decided to get rid of. A strange deal was conducted, during which Kazaa departed to the Australian company Sharman Networks, registered on the Pacific Island Vanuatu. However, something then did not become part of this transaction, something very important is the right and patents for the peergaging technology that was used in Kazaa. These rights remained in the hands of Zennstrem and Frisis, or rather their new Joltid company, registered in general at the British Virgin Islands.

You already probably realize that all these details are not available here. The fact is that it was subsequently this technology and was used when creating Skype.

By the way, if we talk about the role of Frisis and Sennterster in the creation of Skype, then everything has already been familiar to us here - hired programmers (the same Estonians who are kopeli over Kazaa) and two inseparable start-ups in the role of the founders of the project. Although, justice, for the sake of here, it should be noted that Zennstrem was faithful to Skype and remained at the post of CEO until 2007, that is, for two years after the sale of EBay auction.

So eBay. As mentioned above, in 2005, just two years after the creation of Skype was sold to EBay for the fabulous amount - $ 2.6 billion plus another 1.5 billion in a few years, if the financial performance of Skype will be good (it was the largest Acquisition of eBay in the entire history of the auction). Both - and Frisis, and Zennstrom, then overnight became billionaires and, it would seem, could calmly rejoice in life, start and promote other projects, investment and just spend those billions. But it was not there.

Having won four long years after making a deal and have time to start the startup joost during this time, the calculating a couple decided that enough to observe the development of Skype from the side. And the development, by the way, was obvious: the number of users has grown from 53 to more than 400 million, the Skype International traffic in 2008 was a record 33 billion minutes, only Ebay's welcome money did not bring all this. And since Profit from Skype was much more modest amounts, rather planned initially, in 2009 the largest auction of the planet decided to get rid of the acquisition, stating that she intended to allocate Skype to a separate company again and set his shares on the stock exchange. This message made Frisis and Zennstrema suddenly be activated.

Few people initially understood why Ebay did buy Skype at all (official statements were too unconvincing: "For the convenience of communication between users' users,"), but only in 2009 the entire comic situation reached the general community. It turned out that by purchasing Skype himself, Ebay managed to leave the rights and patents to the configured key technology in the hands of its previous owners. Yes, Frisis and Zennstrema in the person of Joltid. And the owners, having learned about the upcoming Skype's exhibition on the stock exchange, developed a rapid activity, starting to return the sold back. So, the New York Times newspaper, for example, merged the rumor that the former owners of Skype had already managed to pushed their billions and are now forced to communicate with private investors, trying to find the missing part of the amount for the "reverse" transaction.

Moreover, smart businessmen immediately made a "warning shot" - since eBay all this time worked with Joltid under license, Frisis and Zennstrom sued the corresponding claim, going to cancel the action of this license in the UK. To start.

Mutual blackmail and lunges toward each other lasted without a small six months. During this time, eBay, as it were, in response to the offer of Zenstrem and Frisis, redeem his brainchild, managed to sell 65% of Skype shares in the Andreessen Horowitz investor group for $ 2 billion. Responsive businessmen immediately sued again, now on the new owners of Skype, accusing them in violation of patents and demanding $ 75 million for every day of "illegal" service. The auction, which Frisis and the Zennstrem also did not leave alone (still, EBay still had 35% of the shares!), Sent a countercadial lawsuit against Joltid to ban the company's use of technology underlying Skype. Understanding that the process is likely to win will not succeed, EBAY representatives just seen their readiness to rewrite Skype from scratch if it is needed.

The end of this circus came quite recently in November 2009. As it is not surprising, the situation was nevertheless resolved the world. eBay, before that, it was categorically refused to pay anything to the ex-owners of Skype, eventually agreed to the transaction. In the lining of Zennstrom and Frisis, they were not left, they not only received places in the Board of Directors, but also urged a 14% stake in Skype. The whole salt situation is that they did not have to get out - eBay agreed to their conditions in exchange for refusal of lawsuits and licensing by their intellectual property.

Of course, we will never know what was the original plan of Zennstrem and Frisis, and whether he existed at all. It is possible that they represented themselves "Return to Skype" somewhat differently, so to speak, in more rainbow light. Perhaps the rights adhered to joltid in the sleeve for a more appropriate case, and the EBay solution to get rid of Skype has forced events. On the other hand, it may be that Frisis and the Zennstrom did not attach anything criminal at all, although it is very difficult to believe that they are "inadvertently" them, Joltid has been opened in the offshore zone.

After the above described, it will be answered by the question: "What will happen to Skype next?", After all, although the delegate is finished, it is impossible to say that everything is completely cloudless. No, no, let them try in any country to ban Softfon or submit to the company to court (recently telecommunication and cellular operators at once, including Russia, including Russia, are very bad on Skype. However, this is connected not so much with the Skype itself, as with VoIP telephony as a whole - in the last Oposhos and by the power of paranoia are often seen a competitor, pest and enemy number one.

Perhaps, in relation to the future, Skype can be said for sure the following: one of the most popular and successful VoIP services, which uses several hundred million people, can simply be shifted into the summer, whatever happens. And if there are two such cunning and hard and stubborn types in the founders of this software, as Niklas Zennstrom and Janus Frisis, Skype will not only disappear, but most likely will find more successful ways to monetize and increase profits.

What is Skype technology?

Unlike many other IP telephony programs, the Skype uses P2P architecture to transmit data. Skype user catalog is distributed across the computer networks of Skype network, which allows the network to be easily scaled to very large sizes (in this moment More than 100 million users, 10-15 million online) without expensive infrastructure of centralized servers. In addition, Skype can route calls through computers from other users. This allows you to connect to each other by users for NAT or firewall, however creates an additional load on computers and user channels connected to the Internet directly.

The only central element for Skype is the identification server on which user accounts are stored and backups of their contact lists. The central server is only needed to install communication. After the connection is set, the computers send voice data directly to each other (if there is a direct connection between them), or via Skype intermediary (Superval - a computer that has an external IP address and open a TCP port for Skype). In particular, if two computers inside one local network, installed a skype connection between themselves, the connection with the Internet can be interrupted, and the conversation will continue until it is completed by users or any communication failure inside the local network.

Thanks to the Skype codecs used (data compression algorithms) SVOPC (16 kHz), AMR-WB (16 kHz), G.729 (8 kHz) and G.711 (ILBC and ISAC also previously used) and with sufficient Internet connection speed ( 30-60 kbps) In most cases, the sound quality exceeds the quality of the usual telephone communication.

When the connection is established between the PC, the data is encrypted using AES-256, to transfer the key of which, in turn, uses a 1024-bit RSA key.

VoIP protocol Skype is closed and used only original by Skype. Using the API to its functions, third-party software programs can be accessed.

Officially confirmed by developer cases of decoding and / or data interception in Skype was not recorded.

For stable video use, the speed of the Internet connection is required from 200 kbps and the clock frequency of the processor from 1 GHz is desirable.

What is Skype story?

The first versions (version 0.97, 0.98) of the program appeared in September-October 2003. The program simultaneously supported 10 languages \u200b\u200band had a simple, logical interface, initially adapted (unlike ICQ and MS-Messenger) for voice communication. Skype when installing, chose the language localization of Windows And I had login login easier and faster than in competing programs. It is easy to install, mastering and using the program quickly attracted the attention of a large number of users. In version 1.2, the answering machine (Voicemail) appeared for the first time, and starting with 1.3 any owner could leave messages to other users, even if they did not use this service. In 1.2, the Skype feature also appeared, allowing to connect account Skype with phone number.

Starting from version 1.4, it is possible to redirect calls to other Skype accounts, as well as on ordinary phones.

In version 2.0, the opportunity to video call appeared, and in 2.5 - the ability to send SMS, Skype organization (this technology is officially disabled from September 1, 2008) and integration with Microsoft Outlook.

In version 3, a service (skype) has appeared that allows users to create a list of firms and give them a description. Now a considerable extent is filled with spam.

Skype 3.5, the Version for Nokia NST-4 CLINT Skype can be installed on a compatible phone or PDA, while there is a significant cost savings due to low system tariffs. However, cellular operators do not want to lose super-profits and in every way brake process. T-Mobile - the largest provider cellular communication In Germany, she stated that the traffic of Internet telephony Skype will be blocked on smartphones iPhone.. It comes to the point that the lobby of cellular operators is trying to ban Skype, and at the same time ICQ, in Russia.

Attempts to ban Skype

Telecommunications Commission and information technologies The Russian Union of Industrialists and Entrepreneurs (RSPP) is preparing recommendations for the ban in Russia Skype. The interests of the relations participating in the RSPP are clear: due to the presence of Skype, millions of Internet users in Russia have the opportunity to bypass existing high rates for international telephone communications. In addition, the prohibition and FSB initiators argue that Skype is difficult to overhear due to the lack of its connection to the cum.

In Belarus, all calls over the network should pass through the state operator, and the use of other international networks, including Skype, is considered a violation of legislation.

The largest European telecommunications company Deutsche Telekom stated that it would block Skype while trying to use it with the iPhone.

Access to Skype can be blocked by hardware. Similar solutions have Verso Technologies and Cisco Systems. In particular, they enjoy the largest Chinese provider China Telecom. Similarly, Skype is blocked in the UAE.

In response to Skype prohibition attempts, its developers began to implement traffic masking tool to bypass VoIP blocking. In addition, Skype can work with proxy servers, VPN and TOR, which practically reduces the effectiveness of its blocking.

For ten years of its existence, Skype is a unique program for free voice communications via the Internet, based on the peer-in-law technology and allowing no fear of the interception of calls, it turned into one of the many Microsoft services, which respected themselves to all respected by the world's special services. How could this happen? The usual thing is money.

Kazaa.

The real story of Skype began in 2000, when two employees of the Swedish telecommunication company Tele2 - Swede Niclas Zennstell with engineering and business education and Dane Janus Frisis, who has no complete secondary education, were attracted to work on entertainment and news portal everyday.com similar to which just came into fashion. It is likely to save, the leadership of the Estonian branch Tele2 placed an advertisement about a set of qualified programmers with a payment about $ 300 per day.

Niklas Zennstere and Janus Friesia.

Three classmates were responding to the announcement - Yaan Tallinn, Ahty Heinla and come Casesalu. Friends still on FIDO, at sunset of the Soviet era, they founded a small Bluemoon Interactive company and even developed quite successful computer game. Kosmonaut. In 1989, she became the first Estonian game selling abroad, and brought them a good money for those times. But by 2000, the company was already on the verge of bankruptcy, so they had come in a couple of days, they studied the simple foundations of PHP and were successfully accompanied to work in Tele2. Another Estonian Toyvo Annus was appointed to lead the developer team.

Portal Everyday.com was launched as soon as possible, but turned out to be commercially unsuccessful. Zennstere and Frisi quit from Tele2 and moved to Amsterdam, where they began to think about creating their own business. The rabid popularity of the Napster file sharing service, which has already begun to pursue the indignant members of the Metallica group in the United States, brought them to the idea of \u200b\u200bcreating something similar, but in collaboration with the representatives of the record and film industry. A team of Estonian programmers has already proven to develop such a network, and in September 2000, Kazaa program was born in Tallinn.

Ahty Heinla, Toyvo Annus and Yan Tallinn.

Unlike Napster, the main problem of which was the presence of a central server where data about connected computers and available files were stored, the intermediate servers were not required for the KAZAA operation. As a result, almost immediately after its appearance, Kazaa client became the most downloaded program on the Internet.

However, Zennstere and Friis did not manage to agree with the labels, which were considered Kazaa as the next intermediary of Pirates, and soon the army of American lawyers began hunting for new businessmen. The Swedes went into running from the plaintiffs, constantly changing the "appearance and passwords", and the whole team began to encrypt the correspondence hard and regularly get rid of the "compromising" information. At the same time, the Estonian government at all initially rejected the request of Americans to interrogate the Bluemoon team for the disclosure of the commercial secrets of Kazaa. Subsequently, however, they were still interrogated in the presence of American lawyers, but no accusations against Estonians were nominated.

As a result, at the end of 2001, KAZAA was sold to the Australian company Sharman Networks, registered on Vanuatu, and a few years later, already in 2006, Zennstere and Frisis from their own funds paid about $ 100 million as part of the settlement of copywriting disputes with four large labels - Universal Music , Sony BMG, Emi and Warner Music, as well as some others.

Skype: Beginning

Meanwhile, the main part of the intellectual property of KAZAA - Pithenan Technology Global Index - remained in the hands of enterprising Swedes: especially for this they registered in the offshore area of \u200b\u200bthe British Virgin Islands company Joltid, which all rights were transferred. And they did it very on time, because now the labels could be sued to sue Sharman Networks, but to get the right to the peergling technology itself and it could not prohibit its use as owners of patents.

Actually, even then, Zennstere and Frisis had an idea of \u200b\u200bcreating an application that could provide a voice connection between any computers connected to the Internet, while completely free. In the hands of partners there was practically finished Global Index P2P technology, only instead of files it was necessary to configure the transmission of digitized voice data.

Of course, the Estonian team of programmers have been connected to the project, and the actual headquarters of Skype was the city of Tallinn. In the spring of 2003, the alpha version of the new application was ready, and it was sent to 20 testers. The name was composed of the words "SKY" ("Sky") and "Peer" ("equal", already in the meaning of the node "Pir") and originally looked like "Skyper", but the domain name Skyper.com turned out to be busy, so partners We decided to just discard the last letter.

At first, the Skype reviews were skeptic, primarily due to the mediocre quality of sound, but one thing is that this application made it possible to communicate with people on the other end of the world for free, made him look at him completely from the other side. In the people who made Kazaa, decided to invest the famous American venture capitalist William Draper, and invested millions returned to him a thousand times more than the amount.

The first is full skype version August 29, 2003 was released, and the same company registered in Luxembourg - a country where foreign jurisdiction intervention in their activities did not welcome legal entities. And it was very reasonable, because Robin Houda File sharing now became the worst enemies of all telecommunications companies in the world. On the very first day, Skype downloaded 10,000 people.

Skype: era eBay

After the experience with Kazaa Skype was originally created as a product protected from interception: all the conversations are necessarily encrypted, and the computers connected to the network should be performed in the role of Servers-Suirusers. The only necessary central network element is a server with user accounts and backups The lists of their contacts that do not contain any other information. Skype with ease byfend the firewalls, skillfully masked his traffic, leakaged through any available ports and left no trace of presence on the Internet.

As a result, for some time he became a favorite tool of criminals of all the masters, and with the opening paid Services (For example, calls to Skypeout phones) even began to be used for "laundering" of money. It is not surprising that law enforcement agencies and intelligence agencies of all countries, as well as representatives of telecommunications companies threw the Luxembourg and London Skype offices with the most diverse angry requirements that the company's lawyers simply sent to the basket without reading.

This was possible not only thanks to the Luxembourg "registration" of the company, but also due to the fact that Zennstere and Frisis have now paid the closest attention to the legal support of the business: the Kazaa experience made them make a maximum effort to ensure that the next enterprise is one hundred percent legal. In particular, Skype has never been registered as a telecom operator, instead, the company was considered a "provider electronic information", Such as an enterprise providing email services.

Up until 2005, Skype reminded a typical high-tech business: price lists for paid services were composed without supporting for some marketing research, the staff was gained according to the results of simple tests, and the amount of salaries and even the deadlines for its payment were not prescribed anywhere. None of the three Skype offices - in Tallinn, Luxembourg and London - there were no tablets, and the cabinets themselves were impossible to find a random person.

At the same time, the number of lawsuits to Skype constantly grew, while Yahoo !, Aol, Microsoft and Google declared their intention in the near future to open similar services. In the summer of 2005, Zennstere and Frisis began negotiations with eBay, and in September it was announced that Skype was made by this largest online auction for $ 2.6 billion: it became the most impressive purchase of eBay in history. Partners woke up billionaires, and the Estonian team of programmers received $ 42 million for each. In addition, another 140 people in Tallinn and London borrowed small stakes in the company.

Hardly in ebay really understood what about They bought, and most importantly - why. Cultural differences between the Estonian and American staff of the company were so great that even corporate parties who took place in Pärnu were simply shocked by Americans. Representatives eBay's hair stood on end when they saw the "live" television broadcast of the Skype 2006 party, where the Zennstere poured the vodka to everyone, and the guests splash right in the pool directly in the clothes.

At the same time, Skype profits brought much less than a headache, and in 2009 they decided to highlight it into a separate company in Ebay, and put it on the stock exchange. And here on the stage, the former owners of Zennstere and Fris were reappearing with a proposal to buy Skype back. Moreover, there was a well-known argument in their arsenal: all the rights to patents were still owned by the offshore Joltid, and the Ebay store enjoyed them under license. Meanwhile, Ebay managed to sell a 65% stake in Skype Inf Prefend Andressen Horowitz, as a result of which Joltid started litigation already against two rivals, accusing them in the illegal use of other patents.

The situation was resolved by the World Agreement with EBay, which did not receive anything in the end, except for refusing to prosecute from Joltid and licenses for their peerging technology. And already in 2011, Skype bought Microsoft for $ 8.5 billion.

Skype: Microsoft Era

The acquisition of Skype also became for Microsoft the largest purchase in history, as well as for eBay. Zennstere and Frisis for the second time they received impressive money for their most successful enterprise. While Skype still remains an independent application over which Microsoft Skype Division works, with offices in Luxembourg, Tartu and Tallinn. But, knowing Microsoft, you can not doubt that in the future this application will only become part of a more large-scale corporate product code, and the Skype name itself will remain in the past.

And, most importantly, there is nothing left of the former degree of negotiations: according to former employee JSC Edward Snowden, US intelligence services fell for Skype's scenes with eBay, and to disguise the technical and legal consequences of such actions, allegedly developed a secret draft of the Chess, which only a few people knew about eBay. There is no doubt that this cooperation continues in the Microsoft Epoch. In addition, the communications technology itself is changed in such a way that it is no longer possible to create supports for some separate computers Inside the network satisfying purely specifications: all their functions are transferred to Microsoft servers.

In turn, the User Agreement now allows access to transmitted data as Microsoft itself and affiliates and Internet providers. A special services of several states have already been open about the availability of negotiations on Skype negotiations, special services of several states are already openly announced, including Russia.

From the entire initial Skype team over the system, only one person continues to work - come Casesal. Annus quit immediately after the sale of the EBay auction system, Tallinn and Heinla lasted a couple of years. All of them are now very wealthy people investing money in a variety of startups: Tallinn, for example, participates in the project on the "salvation of mankind" Lifeboat Foundation and owns the company "Personified Medical Services" Metamed. Billionaires Zennstrem and Friesis enjoy life and are seen in the acts of charity.

Skype B. modern world - This is the number one service for voice and video calls. Since its inception in 2003, the messenger gradually improves his interface to a point where any person with basic skills can master it quickly.

It has paid and free versions. Latest version Allows users to integrate their Skype and Facebook contacts. This popularity of the messenger attracts special attention to the history of its creation.

The first steps

The first question of any user who has been using the program for years and decided to ask her story, is "who came up with Skype?" Initially, Skype founders were Scandinavians Janus Frisis and Niklas Zennstrom, from Denmark and Sweden, respectively. However, developers software There were three - Estonians Ahti Heinla, will come Casesalu and Yan Tallinn, who created the previously famous File Share Kazaa.

Its guys came to mind a great idea - to give any user who has an internet connection, the ability to communicate and talk to any other subscriber. But this is not all, all this would be completely free.

On August 29, 2003, the developers released the first official release of the application, which instantly attracted the attention of thousands of users.

It was something amazing, especially for people from less developed countries, where other ways of communication were expensive, limited or not at all. People very quickly began using Skype as a method for making free calls to any point of the globe. In the blink of an eye, the application has become the world demanded.

The first earnings founders

After such rapid popularity and in demand, the creators had to think that it was time for their product to generate income. They decided to start providing paid services - direct calls to ordinary phones from Skype and vice versa.

And they made it possible to make such challenges at truly reduced prices, many times lower than the usual stationary or mobile calls.

In 2005, the messenger was actively used by more than 70 million people. Skype began to bring good money to the owners (about $ 35 million per quarter). But that was only the beginning.

Shopping Skype eBay.

In the same 2005, the largest and popular EBay auction on the planet buys Skype for amazing at the time at the time of 2.6 billion dollars. The auction owners did not fully understood the development for which this development, but considered a big and profitable deal.

Already in the next year, the Skype revenue increased twice and amounted to about 195 million dollars. The number of active users also rapidly increased to 171 million in 2007, revenue reached $ 381 million, and users have already become 278 million.

For those four years of finding a messenger in possession of eBay, the service has become truly popular and in demand throughout the world. The number of active users during this time has grown from 55 to 400 million.

In November 2009, the program is sold again. Ebay announced that they sold 70% of the company's shares for $ 2.5 billion. Moreover, the very first owners, those who created the program, received a 14% stake in the service and place in the board of directors. Without putting a penny in the development of service. They were simply guaranteed in return to the refusal of legal prosecution eBay for the illegal use of their patent.

Era Microsoft.

In 2010, the number of Skype users reached 663 million, and the income grew by 20% to $ 860 million. But the company continues to lose money, despite the fact that an annual loss amounted to only $ 7 million.

In 2011, Microsoft announced that they were buying Skype and were ready to pay a huge amount of $ 8.5 billion for the transaction. It was the largest acquisition that Windows CDD developers did.

Microsoft managers felt comfortable by paying this amount because they had big plans. They planned to integrate Skype in their applications, such as Windows, MS Office, etc.

Skype today is available to devices running on Windows 2000, XP, Vista, 7, 8 and telephones with Windows. In addition, for Apple and Play Station Portable Sony gadgets.

Development of application versions

Skype 4.1 was launched in 2009. By 2010, Skype 4.1 was rooted in Windows, Mac and Linux. Skype aimed at the mobile market of such devices, like Android, iPhone and iPad. Early versions Allowed only voice calls. In December 2010, Skype video calls became available for iPhone users. By June 2011, androids use the same access.

Skype continues to expand on new markets, becomes available for applications such as Linux, smart televisions, game consoles. In May 2011, after the transition to the possession of Microsoft, version 5.3 comes. It includes Facebook integration and group video calls.

The program was dynamic and significantly exceeded the initial scheme. A large number of Consumers began to move to a new platform with group challenges, unlimited calls in the country and the promise of an interface without advertising.

In November 2012, Microsoft announced that Skype would become the main messaging service. Users can log in with their Microsoft account. The Bing Search panel was also included in the installer.

The messenger is gradually adapted to the overall style of Microsoft.

Skype has already proven itself as a leading video and voice call platform, instant messaging, files and joint chats. Microsoft turned Skype to a winning investment and a stunning program for online voice and video transmission. His creator can be proud of his child.
