Steve Jobs also claimed that a large percentage of the video on the Internet is supported on iOS, since many popular video sharing websites such as YouTube have published video content in an HTML5 compatible format, enabling videos to playback in mobile web browsers even without Flash Player.
Blip (website)
Viewing Blip videos on a PC or laptop required the Adobe Flash Player plug-in to be installed on the browser; mobile viewing was available through a mobile app that was available until early 2014 and functional until August 2015, along with an HTML5 flag on mobile browsers which allowed viewing of videos uploaded in H.264 formats. File size was limited to 1 GB for uploads on the Blip site and the player was Flash-based. The video quality on Blip was optimized using the H.264 video codec and AAC audio codec using a high quality profile. On the site, each show page was encouraged to have a show poster, header graphic and website banner.
