Oh yes, Adobe Edge Animate – what a lovely gem that was !

I'm afraid that brilliant file format has lost all relevance and popularity in the current world... :-(

Somehow, certain obvious and promising technologies just don't make it. If you Google "OAM", no one is using it, no one is endorsing it, no one remembers it. Why not ? Maybe the format was/is too open, and it's too easy to create (in fact it's just packaged HTML5), to distribute, and display.

Companies want clever technologies they can control, measure, and play safe with. Adobe itself steered away from it, because you can't control and measure the distribution of an OAM (just like with ePub Fixed Layout). Underlying technologies like fonts and video codecs are also tricky. Licenses and patents can be too easily ignored or circumvented. So the web, app, and ad industry don't like it at all...

So it's down to either a simple image, a video, or complex HTML5. Plain HTML5 and a slew of proprietary scripts seem easier to work with - from a developer's and distributor's viewpoint.
