YouTube is a video sharing website where users can upload, view and share video clips. YouTube was created in mid-February 2005 by three former PayPal employees.[2] The San Bruno-based service uses Adobe Flash technology to display a wide variety of 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.[3]
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 pornography, nudity, defamation, harassment, commercial advertisements and material encouraging criminal conduct is 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.[4] In January 2008 alone, nearly 79 million users watched over 3 billion videos on YouTube.[5]
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.[6] As of March 22, 2008, a YouTube search returns about 77.3 million videos and 2.89 million user channels.[7][8]
YouTube consumes roughly 1 terabyte of bandwidth a second costing approximately $1 million a day.[5]
History
Domain name problem
YouTube's immense success has unintentionally affected the business of an American company, Universal Tube & Rollform Equipment Corp., whose website, utube.com, was frequently overloaded and shut down by extremely high numbers of visitors unsure about the spelling of YouTube's domain name, but now utube.com is once again operational.[9] At the beginning of November 2006, Universal Tube filed suit in federal court against YouTube,[10] requesting that the youtube.com domain be transferred to them.[11]
Recent events
Political campaigning
Political candidates for the 2008 U.S. Presidential election have been using YouTube as an outlet for advertising their candidacies. Voters can view candidate statements and make videos supporting (or opposing) presidential candidates (e.g., videos for Ron Paul, Hillary Clinton, Barack Obama, and Joe Biden).[12] [13] Third Party presidential candidates have also made extensive use of YouTube. Libertarian Steve Kubby's campaign debuted a short animated film, featuring the faces and voices of campaign contributors who financed its production, on YouTube on September 29th, 2007.[14] The U.S. media has often commented that YouTube played a significant role in the 2006 defeat of Republican Senator George Allen due to a video clip of him making allegedly racist remarks that was continuously replayed by YouTube viewers during the campaign.[15] [16] [17] [18] [19] Political commentators such as James Kotecki have also joined the YouTube world of politics. Many commentators make videos on YouTube critiquing a presidential candidate's YouTube videos, or simply using YouTube as a medium to get their opinions heard. Recently, French and Italian politicians, such as Antonio Di Pietro, have also been using the site as part of their campaigns. YouTube has also been used by former Australian Prime Minister John Howard in the lead up to the 2007 federal election.
CNN-YouTube presidential debates
In the run up to the 2008 Presidential elections, CNN aired a debate in which candidates fielded questions selected from a pool submitted by users of YouTube. Because of the use of technology to aggregate questions from a wide range of constituents, the forum has been referred to as "most democratic Presidential Debate ever".[20]
Social impact
Blocking
YouTube has been blocked in several countries since its inception, including 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. 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.[21] This action by the Pakistani authorities led to a near global blackout of the YouTube site for at least two hours.[22] Thousands of Pakistanis undermined the 3-day block using a VPN software called Hotspot Shield.[23] The YouTube ban was lifted on February 26, 2008 after the "offensive material" were removed from the site.[24]
Schools in certain countries have begun to block access to YouTube due to students uploading videos of bullying behavior, school fights and racist behavior as well as increased bandwidth usage and other inappropriate content.[25]
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 (and more often than not, pornographic) external sites, usually with some enticing statements (such as "Great video, go to <site> for the full version"). To counter this, YouTube now blocks comments with URLs in them; if a user tries to post a comment with a URL, it will be discarded and will now show up. As of February, this "feature" seems to have been extended to profile comments as well, although the user will receive an ambiguous "error processing your comment" message. Also, if a user posts many comments in a short period, they may be asked to complete a CAPTCHA. Other examples of spammers include users who use non-related-to-video threats (most frequently being "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. Originally, this feature was indeed a useful feature to build a bigger community using YouTube. When spammers became aware of this, they decided to give it a try and found every email address possible to send random email invites. More so, they've now been able to cheat the system even more.
The messages came from service@youtube.com. [...] The messages look like a legitimate YouTube invite, except they include typical spam content like stock pump-and-dump promotions and links to spam Web sites. Many of them use Microsoft's recent XBox 360 hit "Halo 3" as bait, telling the recipient they have won a free copy of the game and to go to a Web site. If they take the bait and click on "winhalo3.com," the Web site infects them with the Storm Worm, which has been hanging around since August.[26]
Spammers have used this route more often nowadays because they can use it to defeat spam filters, gain more readers and possibly customers. "They just do as all spammers do..."
Terms of service
According YouTube's terms of service,[27] users may upload videos only with permission of the copyright holder and people depicted in the videos. Pornography, nudity, defamation, harassment, commercial advertisements and material encouraging criminal conduct are prohibited. The uploader grants YouTube a license to distribute and modify the uploaded material for any purpose; this license terminates when the uploader deletes the material from the site. Users may view videos on the site as long as they agree to the terms of service; downloading through one's own means or copying of the videos is not permitted.
Internationalization
On June 19, 2007, Eric E. Schmidt was in Paris to launch the new localization system. The entire interface of the website is now available with localized versions in numerous countries:
Google aims to compete with local videosharing websites like DailyMotion in France. 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.[34][35]
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.
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 18th October due to the censorship of the Taiwanese flag. URLs to YouTube were redirected to China's own search engine, Baidu. It was subsequently unblocked on the 31st of October.[36] As noted, in February 2008, Youtube was blocked in Pakistan and, within a few weeks, the block was removed [37][24]
Technical notes
Video format
As of November 2007 YouTube plays back videos limited in both size and quality. The size is limited to pixel dimensions of 320 by 240 and the quality is limited to a bitrate of around 314kbit/s with a frame rate dependent on the uploaded video.[38]YouTube limits the playback size and quality by re-encoding the user's uploaded video at the time of upload. In 2006 YouTube permitted playback at higher quality, larger sizes, and in stereo, but some time after January 2007 YouTube applied quality reductions to new uploads.[39]
YouTube's video playback technology is based on Macromedia's Flash Player 9 and uses the Sorenson Spark H.263 video codec. 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.[40] 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.
YouTube converts videos into the Flash Video format after uploading.[41] The different files are stored in obscurely named subdomains, accessible either directly or through YouTube's get_video PHP script[dead link]. YouTube also converts content to other formats so that it can be viewed outside of the website. See below.
YouTube officially accepts uploaded videos in .WMV, .AVI, .MOV, MPEG and .MP4, formats[42]
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.
On September 14, 2007, Members of the VIDEOHelp.com forums discovered a method to allow high-quality video and stereo sound.[43] The method involved converting a video to the .flv format YouTube uses, and using a Hex Editor to extend the video's displayed playback time (usually to 10 or 11 minutes for non-Director accounts), thus "tricking" YouTube into believing that the file's bitrate was much lower than it actually was. Although load times significantly increased for videos, both video and sound quality was notably better than in comparable videos uploaded without the method. However, on February 4, 2008, following a maintenance period, YouTube took countermeasures against this method, and it is now impossible to upload high-quality videos[44]. This had no effect on any high-quality videos already uploaded to YouTube. In addition, it seems that any videos that have little movement and are encoded under 350 kbps, while not offering the same amount of quality as those with the trick method, still sound and look better than typical YouTube videos[45]
In March 2008, YouTube launched 'High Quality' versions of its videos. The new version offers a better video definition (480x360) in the AVC format for any video uploaded after this date. YouTube will decide which videos are capable of this improved quality based on the standard of the original upload. Users can choose "always show me higher quality when available" in their Account pages to switch automatically to the better quality.
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."[46]
Recently downloaded videos used to be cached, but as of March 2008, this no longer seems to be the case, and videos must be downloaded each time the user views it.
Audio format
YouTube files contain an MP3 audio stream. By default, it is mono-encoding with a 65kbit/s rate at 22050 Hz. However, it is possible to get a stereo audio track if the movie file is manually converted to FLV format using a program such as ffmpeg for Linux, ffmpegX for Macintosh or the commercial Riva FLV Encoder for Windows.
Content accessibility
On YouTube
As noted above, YouTube accepts common file formats and converts them to the H.263 variant of Flash Video, and makes them available for online viewing. Beginning in June 2007, newly uploaded videos will also be encoded using the H.264 video standard to enable streaming of YouTube videos on the Apple TV, iPhone, and iPod touch.
On Apple TV
Apple Inc. announced on 20 June 2007 that YouTube is accessible on the Apple TV after installation of a free software update. Functionality includes browsing by category, searching videos, and the ability for members to log onto their YouTube accounts directly on Apple TV. Access to thousands of the most current and popular YouTube videos will be available, with plans to add thousands more videos each week. The entire catalog is targeted to be available in fall 2007. According to Apple VP David Moody, the reason for the delay is the need for all current YouTube content to be transcoded to Apple's preferred video standard, H.264. All content uploaded in and after June, however, will be automatically encoded into H.264, rendering additional transcoding unnecessary for these newer files.
On mobile
YouTube launched its mobile site, YouTube Mobile on 15 June 2007. It is based on xHTML and uses 3GP videos with H263/AMR codec and RTSP streaming. It is available via a web interface at m.youtube.com or via YouTube's Mobile Java Application.
On TV
YouTube TV Channel will be on Information TV 2 on January 7, 2008. The channel will air video sharing content from the YouTube website.
On iPhone and iPod touch
Apple announced Wednesday, 20 June 2007 that YouTube would be available on iPhone at launch. Streaming is over WiFi or EDGE.
Videos on YouTube for the iPhone are encoded in Apple's preferred H.264 format. All videos are viewed in the horizontal orientation of the phone. As YouTube videos have 4:3 aspect ratio and the iPhone is 3:2, videos must be viewed with black bars on the side (pillarboxed) or may be zoomed to trim some of the top and bottom to fill the screen.
Not all videos are available on iPhone yet because not every video has been reencoded to H.264. There are two versions of each video on YouTube, one is higher bandwidth for WiFi use, and one is lower resolution for EDGE use.
Unlike the Apple TV version, users cannot log in to their own YouTube accounts, but can create a separate favorites list just for the iPhone.
Outside YouTube
Each video is accompanied by the full HTML markup for linking to it and/or embedding it within another page, unless the submitter of a video chooses to disable the embedding feature. A small addition to the embeddable markup will allow the video to play automatically when the webpage loads. These simple cut-and-paste options are especially popular with users of social-networking sites. Poor experiences, however, have been cited by users of such sites,[47] where autoplaying embedded YouTube videos has been reported to slow down page loading time or even to crash internet browsers.
The YouTube Player is the name of another embeddable applet (with a different interface), designed for browsing YouTube videos on an iGoogle homepage.
YouTube itself does not make it easy to download and save videos for offline viewing or editing (in fact, YouTube's official FAQ even states that "you can't download our videos to your computer") nor for viewing in external players, but several third-party web sites, applications, browser extensions (such as Firefox extensions) exist for that purpose. Alternatively, most .flv files can be copied from the 'Temporary Internet Files' folder in Windows, or the /tmp directory in GNU systems, to a permanent folder. The .flv files can then be viewed and edited directly or converted to other formats using various applications such as VLC media player or FLVPlayer.
YouTube Remixer
On June 18, 2007, YouTube launched its online video editing tool, YouTube Remixer. The tool allows users to edit their YouTube videos online, although the editing tools are very limited.
Channel type
Members of YouTube.com are offered to be a part of groups called "Channel Types" that make their channel more distinctive. The types are:
- YouTuber, a general viewer of YouTube.
- Director, movie makers displaying their videos for YouTube viewers.
- Musician, musicians or bands covering songs or displaying originals or giving lessons on songs, scales, chords, etc.
- Comedian, comedians displaying their comedy bits for YouTube viewers.
- Guru, people who are experienced in a certain field make videos of what they do.
Video rankings
YouTube awards videos with honors, the most popular of which is "most viewed"[48] which are divided into four categories: today, this week, this month and all time. Honors include:
- Most Viewed topped by Judson Laipply's Evolution of Dance
- Top Rated
- Most Discussed
- Top Favorites
- Most Linked
- Recently Featured
- Most Responded
YouTube Video Awards
In 2006, YouTube presented the annual YouTube Video Awards.[49] Categories include "'most adorable video ever" and "most creative." YouTube nominates the contenders, and users decide the winners. Only original, user created videos are nominated. Nominees for the 2006 awards included Peter Oakley (geriatric1927), LonelyGirl15, thewinekone, Renetto and Chad Vader.[50][51]
