Aw yes. And Minidisc was better than CD and DIVx better than DVD, and SACD better than DVD-Audio...But yet none of them won out either.

And what do Beta-Max, Minidisc, and SACD all have in common? Sony! I wonder who is going to win the HD-DVD blueray battle 
Are the examples you are showing an attempt to point out how the superior format lost because of non technological reasons? Does that not re-enforce the point Tony-S was making about how windows, an inferior technology, was able to achieve market dominance not because it was better, but because IBM dropped the ball? What is it exactly you are trying to say here?
Comparing divx to dvd is more apples to fishsticks. DVD is a medium, divx is a format. The format that DVDs use is called mpeg2, divx is mpeg4 and it IS winning out. Not so much as in beating mpeg2, just replacing it. Almost any video you download off the interweb now is mpeg4 and both blueray and hd-dvd players are required to support it. A good portion of $40 off the shelf walmart dvd players sold today also support divx. My archos plays mpeg4 and my p&s samsung camera records video natively to mpeg4 as well.
And thanks for the insight.
