Within the scene of mobile HW, they commonly had HW codecs for H263 and 
MPEG4 (or SW codecs), with many but not all also supporting H264. So for 
one specific generation of mobile devices, MPEG4 was the same level of 
lingua franca that H264 is today.

Obviously not a big use case today in nontrivial numbers of course, but 
it is an example of a "scene" where the codec did have a pretty broad 
adoption.

I guess that's true.
