The site is praised as one the most user friendly sites on the Internet. Unregistered users can watch most videos on the site while registered users have the ability to upload an unlimited number of videos. Related videos, determined by the title and tags, appear to the right of the video. In the second year, the site gave users the ability to post responses and subscribe to any registered user.[citation needed]
YouTube's popularity has led to the creation of many YouTube Internet celebrities, popular individuals who have attracted significant publicity in their home countries from their videos. The most subscribed YouTube member, as of April 6, 2007, is lonelygirl15. For these users, the Internet fame has had various unexpected effects. By way of example, YouTube user and former receptionist Brooke Brodack from Massachusetts has been signed by NBC's Carson Daly for an 18-month development contract.
Band and music promotion
YouTube has also become a means of promoting bands and their music. One such example is OK Go which got a huge radio hit and an MTV Video Music Awards performance out of the treadmill video for Here It Goes Again. In the same light, a video broadcasting the Free Hugs Campaign with accompanying music by the Sick Puppies led to instant fame for both the band and the campaign, with more campaigns taking place in different parts of the world. The main character of the video, Juan Mann has also achieved fame, being interviewed on Australian news programs, even appearing on The Oprah Winfrey Show.
Video format
YouTube's video playback technology is based on Macromedia's FlashPlayer 7 and uses the Sorenson Spark H.263 video codec. This technology allows YouTube to display videos with quality comparable to more established video playback technologies (such as Windows Media Player, Realplayer or Apple's Quicktime Player) that generally require the user to download and install a web browser plugin in order to watch video. Flash itself requires a plug-in, but the Flash 7 plug-in is generally considered to be present on approximately 90% of Internet-connected computers. Alternatively, users can use a number of websites to download the videos to their own computers.
YouTube converts videos into .FLV (Adobe Flash Video) format after uploading. The extension is then stripped from the file (Extension can be found again with TrID). The different files are stored in obscurely named subdomains, to make ripping the videos difficult.
