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 You Tube users can upload videos up to 15 minutes each in duration.
Videos with progressive scanning or interlaced scanning can be uploaded, but for the best video quality, You Tube suggests interlaced videos be deinterlaced before uploading.
All the video formats on You Tube use progressive scanning.
Google product manager Shiva Rajaraman commented: "We really felt like we needed to step back and remove the clutter." In February 2015, You Tube released a secondary mobile app known as You Tube Kids.
The app is designed to provide an experience optimized for children.
The You Tube site had a page that allowed supported browsers to opt into the HTML5 trial.
