RE[5]: H.264 vs VP8 comparison

in reply to "RE[4]: H.264 vs VP8 comparison"
PNG was created when patent fears about GIF began to seem reasonable. It is not reasonable to compare PNG and GIF therefore because for many years there was no such option; the choices were JPEG and GIF, or to take a chance that the client would support some other format and have the bandwidth to download it.
PNG is superior to GIF in almost every way. It does not animate and under certain very specific scenarios has inferior compression. Other than those it is superior.
PNG is superior to JPEG in image quality, being lossless, but for photographic imagery compresses much less well.
Today GIF is used almost exclusively for its animations, since no other means of animation is natively supported by all browsers.

Enjoy. Especially Chompy. (You will need Firefox 3.0 or later, or Opera).

That's the problem. I'd love to see a modern standard for animation on the web, but IE does not implement APNG and Apple, in their usual love of open media standards, didn't implement support for it in Webkit so the number of browsers which do not support it is likely going to increase in the upcoming years...
Moreover, the PNG guys, pissed off because their bloated MNG format did not get as much attention as they wanted, declared APNG as unsupported and vandalized its wikipedia page, favoring market fragmentation.
(PS : About PNG, I don't understand why there's 3 rows of thumbnails : GIF, APNG, and ?)
