HTML5 video
In 2010, in the wake of Apple iPad launch and after Steve Jobs announced that Apple mobile devices would not support Flash, a number of high-profile sites began to serve H.264 HTML5 video instead of Adobe Flash for user-agents identifying as iPad. HTML5 video was not as widespread as Flash videos, though there were rollouts of experimental HTML5-based video players from DailyMotion (using Ogg Theora and Vorbis format), YouTube (using the H.264 and WebM formats), and Vimeo (using the H.264 format).
Comparison of HTML5 and Flash
The table below compares the features of the Flash platform, the HTML5 specification and the features implemented in modern web browsers.Web browsers cannot render Flash media themselves. Instead, Flash is primarily rendered via the proprietary, but freely available, Adobe Flash Player. Until 2008, there was no official specification by which to create an alternative player. Alternative players have been developed before 2008, but they support Flash to a lesser degree than the official one.
