Karim could not easily find video clips of either event online, which led to the idea of a video sharing site.According to data published by market research company com Score, You Tube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010..You Tube videos are available in a range of quality levels.
All You Tube users can upload videos up to 15 minutes each in duration.
Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, as well as live streams, which requires verifying the account, normally through a mobile phone.
Google product manager Shiva Rajaraman commented: "We really felt like we needed to step back and remove the clutter." In May 2013, You Tube launched a pilot program to begin offering some content providers the ability to charge $0.99 per month or more for certain channels, but the vast majority of its videos would remain free to view.
In February 2015, You Tube released a secondary mobile app known as You Tube Kids.
Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
You Tube earns advertising revenue from Google Ad Sense, a program which targets ads according to site content and audience.
Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that You Tube was founded after a dinner party "was probably very strengthened by marketing ideas around creating a story that was very digestible".
Karim said the inspiration for You Tube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami.
All the video formats on You Tube use progressive scanning.
With this new feature, You Tube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In July 2010, You Tube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels.
Previously, viewing You Tube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser.
