YouTube was created in February 2005 by three former PayPal employees. The San Bruno-based service uses Adobe Flash Video technology to display a wide variety of user-generated video content, including movie clips, TV clips and music videos, as well as amateur content such as videoblogging and short original videos. In October 2006, Google Inc. announced that it had reached a deal to acquire the company for US$1.65 billion in Google stock. The deal closed on November 13, 2006. Unregistered users can watch most videos on the site, while registered users are permitted to upload an unlimited number of videos. Some videos are available only to users of age 18 or older (e.g. videos containing potentially offensive content). The uploading of videos containing defamation, harassment, commercial advertisements and material encouraging criminal conduct is strictly prohibited. Related videos, determined by title and tags, appear onscreen to the right of a given video. In YouTube's second year, functions were added to enhance user ability to post video 'responses' and subscribe to content feeds. Few statistics are publicly available regarding the number of videos on YouTube. However, in July 2006, the company revealed that more than 100 million videos were being watched every day, and 2.5 billion videos were watched in June 2006. 50,000 videos were being added per day in May 2006, and this increased to 65,000 by July. In January 2008 alone, nearly 79 million users had made over 3 billion video views. In August 2006, The Wall Street Journal published an article revealing that YouTube was hosting about 6.1 million videos (requiring about 45 terabytes of storage space), and had about 500,000 user accounts. As of April 9, 2008, a YouTube search returns about 83.4 million videos and 3.75 million user channels. It is estimated that in 2007, YouTube consumed as much bandwidth as the entire Internet in 2000, and that over 13 hours of video are uploaded every minute. In March 2008, its bandwidth costs were estimated at approximately $1 million a day. As of Q1 2008, YouTube was not profitable, with its revenues in 2007 being noted as "not material" by Google in a regulatory filing. Exact revenue or profit numbers are not published, but a June 2008 Forbes magazine article projected the 2008 revenue at $200 million, noting progress in ad sales. At that time, the price for an ad on the YouTube home page was $175,000 per day (plus a $50,000 commitment to buy Google/YouTube ads elsewhere), and a branded channel (distinguished by a customized background) cost advertisers $200,000 Blocking YouTube has been blocked in several countries since its inception, including Tunisia, Thailand (which has since been lifted) and Iran. Certain video pages were banned as of October 1, 2007 in Turkey, but this was lifted two days later. More recently on January 22, 2008 Turkey banned YouTube once again but this ban was lifted after three days. YouTube was blocked in Turkey between May and August 2008 after controversy over videos deemed insulting to Mustafa Kemal Atatürk . Certain pages are also banned in United Arab Emirates. On February 23, 2008, Pakistan blocked YouTube due to "offensive material" towards the Islamic faith, including the display of pictures of the prophet Muhammad. This action by the Pakistani authorities led to a near global blackout of the YouTube site for at least two hours. Thousands of Pakistanis undermined the 3-day block using VPN software called Hotspot Shield. The YouTube ban was lifted on February 26, 2008 after the "offensive material" were removed from the site. YouTube has been subject to threats of censorship by various countries because of the content it hosts. It was blocked from Mainland China from the October 18, due to the censorship of the Taiwanese flag. URLs to YouTube were redirected to Mainland China's own search engine, Baidu. It was subsequently unblocked on October 31. Schools in certain countries have begun to block access to YouTube due to students uploading videos of bullying behavior, school fights, racist behavior, and other inappropriate content as well as the increased bandwidth usage. Spamming With recent improvements to e-mail spam filtering technology and their wider use, spammers have begun using YouTube as way to advertise: popular videos frequently have comments with links to irrelevant external sites, usually with some enticing statements (such as "Great video, go to <site> for the full version"). To counter this, YouTube has blocked comments with URLs in them since late 2006; if a user tries to post a comment with a URL, it will be discarded and will not show up. As of August 2007, this "feature" seems to have been extended to profile comments as well, although the user will receive an ambiguous "error processing your comment" message. However, posting links is still possible in bulletins, private messages, or group discussions. Also, if a user posts many comments in a short period, they may be asked to complete a CAPTCHA, which was implemented when a notorious spammer abused the lack of a flood control. However, the lack of a CAPTCHA is still present in some areas of the site. Other examples of spammers include users who use non-related-to-video threats (including "Post this message to <number> friends or your mom will die in <number> hours"). They may also send messages to a user's inbox (essentially in the form of a plain-text spam email). Some of these spam accounts also posted pornographic videos on YouTube. A slightly newer feature of YouTube is the ability to send invites to people through email by using the "Invite Your Friends" feature. This feature's intention was to build a bigger community on YouTube. When spammers became aware of this, they abused this feature to generate more spam. Technical notes Video format YouTube's video playback technology is based on Macromedia's Flash Player. This technology allows the site to display videos with quality comparable to more established video playback technologies (such as Windows Media Player, QuickTime and RealPlayer) that generally require the user to download and install a web browser plugin in order to view video. Flash also requires a plug-in, but Adobe considers the Flash 7 plug-in to be present on about 90% of online computers. YouTube's standard and default high quality videos are streamed using the Flash Video (.flv) format with the Sorenson Spark H.263 video codec. Users can view videos in windowed mode or full screen mode and it is possible to switch modes during playback without reloading it due to the full-screen function of Adobe Flash Player 9. The video can also be played back with third-party media players such as GOM Player, gnash, VLC as well as some ffmpeg-based video players. Videos uploaded to YouTube are limited to ten minutes in length, and a file size of 1GB. One video at a time can be uploaded through the standard interface, and multiple videos can be uploaded with a Windows based plugin. YouTube accepts videos uploaded in most formats, including .WMV, .AVI, .MOV, MPEG, .MP4, DivX, .FLV and .OGG. It also supports 3GP, allowing videos to be uploaded directly from a mobile phone. Standard and high quality videos Standard video is Flash Video 320x240 pixels using the H.263 video codec. In March 2008, YouTube launched a feature which allows some of its videos to be viewed in 'High Quality' format. The high quality videos are available in two versions, both of which have a maximum picture size of 480 x 360 pixels. By selecting the "watch in high quality" option or adding &fmt=6 to the web address of a video, it is also played using the H.263 codec with mono sound, and by adding &fmt=18, it is played using the H.264/MPEG-4 AVC codec with AAC audio incorporating two audio channels allowing for stereo sound. YouTube decides which videos are capable of this improved quality based on the standard of the original upload. When asked why YouTube did not choose HD format, the site answered: "Our general philosophy is to make sure that as many people as possible can access YouTube and that videos start quickly and play smoothly. That's one reason why you don't see us racing to call this "Super Duper YouTube HD," because most people don't want to wait a long time for videos to play." Audio format The standard and default high quality videos contain an MP3 mono audio stream as part of the Flash Video file. The audio portion of standard quality video has a bit rate of 64 kbit/s sampled at 22050 Hz, giving an audio bandwidth of around 10 kHz. The default bit rate delivers passable but not hi-fi audio quality. Audio with the "watch in high quality" option is 96 kbit/s at 44100 Hz monaural. Videos played using &fmt=18 added to the web address of the video have two audio channels at around 120 kbit/s, 44100 kHz using AAC sound, giving them the potential for stereo audio. Annotations In June 2008, YouTube launched a beta test of Annotations, which can display notes or links within a video. Annotations allow for information to be added, for example stories with multiple possibilities (viewers click to choose the next scene), and links to other YouTube videos. Initially, annotations would not appear on videos embedded outside the YouTube website, but as of August 2008, it is now available on embedded movies.

It also made an agreement with local television stations like M6 and France Télévisions to legally broadcast video content. On October 17, 2007 it was announced that a Hong Kong version had been launched. YouTube's Steve Chen said its next target will be Taiwan. On October 22, 2007 YouTube New Zealand had its launch party, stating that its aim was to help create YouTube celebrities within New Zealand. This was quickly evident with the rise of such New Zealand YouTube shows as Three Best Friends That Live Together and LiveFromJoes. Plans for YouTube to create a local version in Turkey have run into problems, since the Turkish authorities asked YouTube to set up an office in Turkey, which would be subject to Turkish law. YouTube says that it has no intention of doing this, and that its videos are not subject to Turkish law. Turkish authorities have expressed concerns that YouTube has been used to post videos insulting to Mustafa Kemal Atatürk and other material offensive to Muslims. Channel type Members of YouTube.com are offered to be a part of groups called "Channel Types" that make their channel more distinctive. At one time, when a person signed up for a Director account setting, he or she was offered to have unlimited video length, but that is no longer offered, although the users who joined the "Director" group during that time still have that unlimited video length setting. At that time, they were still also limited to 100MB in video size, but now these accounts are limited to 1GB. The types are: Comedian, comedians displaying their comedy bits for YouTube viewers. Director, movie makers displaying their videos for YouTube viewers. Guru, people who are experienced in a certain field make videos of what they do. Musician, musicians or bands covering songs or displaying originals or giving lessons on songs, scales, chords, etc. Non-profit, a status obtained by 501(c)(3) non-profit organizations accepted into YouTube's non-profit program. Reporter, civilians or professionals who make videos about local or international news and current events. YouTuber, a general viewer of YouTube. Video rankings YouTube awards videos with honors, the most popular of which is "most viewed" which are divided into four categories: today, this week, this month and all time. Honors include: Most Viewed Top Rated Most Discussed Top Favorites Rising Videos Recently Featured Most Responded It is the honors Blackhatter are working to get. This tends to give the video lot's of traffic and hopefully hits to the websiter he or she is promoting. A note about Most Viwed. To get an honor for most viwed, one have to understand it's not the amount of total hits on the video, but the amount of uniq hits on the video. Exampel: Controversies over video rankings The viewing figures of some YouTube videos have been the subject of controversy, since there have been claims that automated systems have been used to inflate the amount of views received, which is forbidden by YouTube's terms of service. In March 2008, an unofficial video of the song "Music Is My Hot Hot Sex" by the Brazilian band Cansei De Ser Sexy briefly held the number one slot for the all-time most viewed video, with around 114 million views. It was temporarily removed from YouTube after allegations of automated viewing or hacking, before being deleted by the uploader. A spokesperson for YouTube commented: "We are developing safeguards to secure the statistics on YouTube. Although it is somewhat difficult to track how often this happens, it is not rampant. As soon as it comes to our attention that someone has rigged their numbers to gain placement on the top pages we remove the video or channel from public view." Clarus Bartel from Italy, who had uploaded the video, denied attempting to boost its ranking, stating: "These gimmicks do not belong to me. I've got nothing to do with it. The accusations geared towards me have saddened me greatly." The YouTube video of the Avril Lavigne song "Girlfriend" has also been accused of having an exaggerated number of views due to the use of a link with an auto-refresh mechanism posted by AvrilBandAids, a fansite devoted to Avril Lavigne. Clicking on the link will automatically reload the YouTube video of Girlfriend every fifteen seconds. Fans of Avril Lavigne are encouraged to: "Keep this page open while you browse the internet, study for exams, or even sleep. For extra viewing power, open up two or more browser windows at this page!" The video of Girlfriend overtook Evolution of Dance by Judson Laipply as the all-time most viewed video on YouTube in July 2008. As of October 2008, Girlfriend has around 105 million views, whilst Evolution of Dance has around 101 million. A YouTube video featuring the anime franchise Evangelion has a view count of around 98 million (as of October 2008), but has been barred from the YouTube charts due to automated viewing.
