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).
Vorbis
As originally recommended by HTML 5, these web browsers natively support Vorbis audio (without a plug-in) using the codice_1 element: Mozilla Firefox 3.5 (and later versions), Google Chrome (from version 3.0.182.2), SeaMonkey (from version 2.0). Opera 9.5 experimental video builds released in 2007 and 2008 have only codice_2 support and play back Vorbis audio included in Ogg video files. Opera 10.5 browser has support for Vorbis audio, WAVE PCM audio and Theora video.
