Why don't we use Animated PNGs (*.apng)?
The .apng file would work PERFECTLY for so many things I have in mind - and, in fact, they would be perfect for so many other things - so why is it that they aren't a globally supported file type? Sure, gifs exist, however they are HEAVILY finicky. They do support more than 256 colors (http://phil.ipal.org/tc.html), and can be lossless, however they don't have the properties and they don't work the same as PNGs. As well, I do know that png files are lossless and are therefor huge, but that's an issue that already has to be worked out with the standard PNG file, so an animated png file would obviously share the same problems.
And if it's because the internet can't change because people are so used to gifs, is there anything anyone can do to help animated png files become a more globally supported file type?

OK, I had not heard of APNG.
In HTML5 you can embed a real video directly, with real motion compression. However, format wars between
Microsoft and Mozilla seem to leave no common codec between IE and Firefox (IE does only commercial h.264, Firefox - at least on Linux - does only open-source webm and Ogg) so you'd have to switch in javascript - a pain on message boards and public forums. But W3C think they have solved the problem of embedding video in webpages, so probably aren't interested in supporting APNG.
Years ago there was an animation type FLC that allowed loops and step backs so you could make things like steam engines, but it got forgotten when computers got enough RAM to do real video.
