http://www.ihollywoodforum.com/documents/IPTV/15.ppt shows certainly more than a 20% bitrate reduction.
It shows 25 to 35% bitrate reduction, and it's a document meant to promote Mpeg4 over Mpeg2, so I think I'll prefer my figures.

Anyway, the document claims a 50-66% bitrate reduction for AVC and it's an overstatement. 50%, perhaps, 66%, never.

For video distributed over the internet: legitimate, illegitimate, or both MPEG-4 has been quite popular.
Legitimate ? where ? I can see WMV, VP6, RV, MOV ( h264, sorenson, and sometimes Mpeg4 SP ). But nothing else.

I still stand by my point of view : mpeg4 sp/asp only broke through for illegitimate distribution.
