Slide 19 of

MPEG-4 was only the current standard for a narrow windows. There weren't many standards between DVD and HD-DVD for MPEG-4 Part 2 to be adopted by. ASP was only finalized in 2002. I'll admit some of the more ambitious profiles of MPEG-4 did fail but certainly not SP/ASP. It also depends on what segment of the industry to which you are are referring. The stated goal of MPEG-4 was for streaming/mobile platforms so it's no surprise it wasn't adopted for broadcast use and the like. For video distributed over the internet: legitimate, illegitimate, or both MPEG-4 has been quite popular.
