		_delirium on March 29, 2013 \| parent \| context \| favorite \| on: Richard Stallman on the Ogg Vorbis license (2001) For some applications Ogg did take over. Music in videogames is often Ogg-encoded due to potential legal problems with including mp3 support. For end users I'm actually not sure either MP3 or Ogg are dominant anymore. I would guess the iTunes Store's choice of AAC has pushed that format significantly.

Not to mention Spotify uses ogg. But it is not user-visible.
