VK (service)

• Messaging. VK Private Messages can be exchanged between groups of 2 to 500 people. An email address can also be specified as the recipient. Each message may contain up to 10 attachments: Photos, Videos, Audio Files, Maps (an embedded map with a manually placed marker), and Documents.[10]
• News. VK users can post on their profile walls, each post may contain up to 10 attachments – media files, maps, and documents (see above). User mentions and hashtags are supported. In case of multiple photo-attachments the previews are automatically scaled and arranged in a magazine-style layout. The news feed can be switched between all news (default) and most interesting modes. The site features a news-recommendation engine, global real-time search and individual search for posts and comments on specific users' walls.
• Communities. VK features three types of communities. Groups are better suited for decentralised communities (discussion-boards, wiki-style articles, editable by all members, etc.). Public pages is a news feed-orientated broadcasting tool for celebrities and businesses. The two types are largely interchangeable, the main difference being in the default settings. The third type of community is called Events, which are used for organizing concerts and events in an appropriate way.[11]

Like button on VK (Russian version)

• Like buttons. VK like buttons for posts, comments, media and external sites operate in a different way from Facebook. Liked content doesn't get automatically pushed to the user's wall, but is saved in the private Favorites section instead. The user has to press a second 'share with friends' button to share an item on their wall or send it via private message to a friend.
• Privacy. Users can control the availability of their content within the network and on the Internet. Blanket and granular privacy settings are available for pages and individual content.
• Synchronization with other social networks. Any news published on the VK wall will appear on Facebook or Twitter. Certain news may not be published by clicking on the logo next to the "Send" button. Editing a post in VK does not change the post in Facebook or Twitter and vice versa. However, removing the news in VK will remove it from other social networks.
• SMS service. Russian users can receive and reply to a private message or leave a comment for community news using SMS.
• Music. Users have access to the audio files uploaded by other users. In addition, users are able to upload the audio files themselves, create playlists and share audios with others by attaching to messages and wall posts. The uploaded audio files cannot violate copyright laws.[12]

As of May 2017, according to Alexa Internet ranking, VK is one of the most visited websites in some Eurasian countries. It is:

• The most visited in Russia;[13]
• 2nd most visited in Belarus;[14]
• 3rd most visited in Kazakhstan;[15]
• 4th most visited in Estonia,[16] Kyrgyzstan[17] and Moldova;[18]
• 5th most visited in Latvia.[19]

It was the fourth most viewed site in Ukraine until, in May 2017, the Ukrainian government banned the use of VK in Ukraine.[20] According to a study for May 2018 conducted by Factum Group Ukraine VK remained the fourth most viewed site in Ukraine, but Facebook was twice as much visited.[21] For 2019, VK appeared as the most visited social network in Ukraine according to Alexa.[22] According to the Internet Association of Ukraine the share of Ukrainian Internet users who visit VK daily had fallen from 54% to 10% from September 2016 to September 2019.[23] They also claimed in November 2019 that Facebook was the most popular social network of Ukraine.[23]

As of May 2018, the site is available in 86 languages, while advertisements are only shown in the Russian and Ukrainian versions. Russian-speaking users can choose between the standard Russian version and two extras: a Soviet version and a Pre-Revolutionary version. Other than language tweaks (e.g. telegrams for messages and comrades for friends), these versions contain other easter eggs. For example, all private messages in the Soviet version have a stamp saying 'passed server censorship'. The pre-revolutionary version uses old-style Russian orthography. Both extra versions are also ad-free.

In 2008, the leading Russian television channel TV Russia (tv channel name RTR used in 1991–2002) (then Russia 1) and television company VGTRK sued VKontakte (then VK) over unlicensed copies of two of its films which had been uploaded by VK users. In 2010, this dispute was settled by the Russian Supreme Arbitration Court in favour of the social network. The court ruled that VK is not responsible for its users’ copyright violations, taking into account that both parties agreed with the technical possibility to identify the user who posted illegal content and who, consequently, must incur the liability.[41] Another ruling early in 2012 went partially in favor of Gala Records (now Warner Music Russia), a recording studio, when the same court ordered VK to pay $7000 for not being active enough in regard to copyrighted materials.[42]

VK offers a content removal tool for copyright holders.[43][44] Large-scale copyright holders may gain access to bulk content removal tools.[45]

Since 2010, VK has also entered several partnerships with legal content providers such as television networks.[46] and streaming providers.[47] Most notably, the Video on Demand provider IVI.ru that has secured licensing rights with all Hollywood majors in 2012.[48] These partnerships allow providers to remove user-uploaded content from VK and substitute it with legal embedded copies from the provider's site.[49] This legal content can be either ad-sponsored, subscription-based, or free, depending on the provider's choices. VK does not display its own advertising in the site's music or video sections, nor in the videos themselves. On October 2013, VKontakte was cleared of copyright infringement charges by a court in Saint Petersburg. The judge ruled that the social network is not responsible for the content uploaded by its users.[50]

In November 2014, the head of The Federal Service for Supervision of Communications, Information Technology and Mass Media, Maxim Ksenzov, said that Vkontakte would complete the process of legalization of the content at the beginning of 2015. At that time (November, 2014), negotiations between major label companies and the social network Vkontakte were ongoing.[51]

Because the social network is one of the most popular and visited sites in runet, its visits can be used to make DDoS attacks on smaller sites. VK performed DDOS attacks on certain sites, making users' browsers send multiple requests to the target site without their consent. The targets were the Runet Prize voting page in 2008[52] and the CAPTCHA-solving service antigate.com in 2012.[53][54] It was done by inserting an iframe and a piece of JavaScript code which periodically reloaded the iframe. As a countermeasure, antigate was detecting whether iframe was loaded from VK and if it were antigate had redirected request to xHamster, a pornography website. VK needed to cease the attack due to the site's use by children. VK tried to use XMLHttpRequest to solve this problem, but had forgotten about the same-origin policy. They succeeded in stopping the attack, though there were many ways to solve the problem with redirect.

Durov was dismissed as CEO in April 2014 after he had failed to retract a letter of resignation. Durov contended that the resignation letter was an April fools prank.[36] Durov then claimed Vladimir Putin's allies had, in effect, taken over the company,[36][38][55] and suggested his ousting was the result of his refusal to hand over personal details of users to the Russian Federal Security Service and his refusal to shut down a VK group dedicated to anti-corruption activist Alexei Navalny.[36][38]

VK organized their first 24-hour Hackathon in 2015 from 31 October to 1 November. The participants were invited to develop projects united by a common idea: “Make it Simple!” (Russian: «Упрощайте!»). 34 teams took part in the competition. A prize pool of 300 thousand rubles was split among the winners.[65]

The second VK Hackathon took place from 26 November to 27 November 2016. The participants developed projects for the community app platform. The “Search for Lost Cats” (Russian: «Поиск пропавших котиков») app won the “Developers’ Choice” category. The prize pool for the event was 300 thousand rubles.[66]

The third VK Hackathon took place from 20 October to 22 October 2017 with 320 participants competing in the event. The prize pool was one million rubles. An application designed to help users navigate the State Hermitage Museum won the “Culture” category.[67]

In 2011, Pavel Durov and Yuri Milner created Start Fellows, a grant program founded to support projects in the field of technology. In 2014, VK took over the Start Fellows program and made it more systematic. The grant was provided to 3 companies each month and included project consultation from VK along with 25 thousand rubles a month for advertisement on the VK platform. Winners of the grant include “University Schedules” (Russian: «Расписание вузов»), a scheduling app, LiveCamDroid, a mobile streaming service, HTML Academy, an educational project, and others.

VK re-launched the project in 2017. Only active projects with an earnings model could submit applications. 327 grant applications were received but only 67 of them passed the initial screening. The total prize pool was 2.5 million rubles.[68]

The first VK Cup, a programming championship for young programmers aged 13–23, was held on 16 July 2012 in Saint Petersburg, Russia.

VK and Codeforces co-organized the fourth VK Cup which took place from 8 July to 9 July 2017. Teams from 52 countries applied to take part in the competition. The prize pool for the competition was 2.5 million rubles.[71]

The first VK Music Awards ceremony took place on 25 December 2017. The VK Music Awards were produced by Timur Bekmambetov and the Bazelevs Company with Pavel Volya hosting the event.[72] The awards ceremony was held in the form of an online live stream.[73] Any VK user could watch the broadcast live. After the ceremony, a private concert was held in the Vegas City Hall in Moscow. Tickets to the event could be won through a contest held in the VK Music community.[72] VK Music Awards winners were determined by the number of plays an artist's song got on VK and the BOOM app. The names of the 30 award winners were published on the official VK Music Awards community page and on the BOOM app website. “Rosé Wine” (Allj and Feduk), “Lambada” (T-Fest and Scriptonite), and “My Half” (MiyaGi and Endspiel) topped the list of most listened to songs. The official pages of all award winners have been marked with a special symbol.[74]

Since 2015, VK has held a yearly 2-day open-air music and entertainment festival. This festival traditionally takes place on a weekend in July at the 300th Anniversary Park (Russian: Парк имени 300-летия Санкт-Петербурга) in St. Petersburg, Russia. According to data from the organizer, 70 thousand people attended the festival in 2016, with the number rising to 85 thousand attendees in 2017. In 2017, around 40 artists and groups performed on 3 stages, including Little Big, The Hatters, and others. Bloggers and other famous individuals, such as Dmitry Grishin, Timur Bekmambetov, and Mikhail Piotrovsky (speakers at the 2017 festival), are also an important part of the festival. More than 1.5 million people watched the festival's official live stream.[75]
