That's one of the world's highest traffic sites making that move. It'll still use Flash for gaming, but everything else is HTML5.

The beginning of the end.

Wonder when all the pr0n sites will make this move? :)

Good on them. My clients don’t do video - shaky, unevenly-lit footage just doesn’t cut it these days. However, having taken a month out of ‘paying’ work to get a fuller understanding of what CSS3 and HTML5 can do, it's a revelation. In another life, I used Quark Xpress for a living, and a couple of other tools - Photoshop and Illustrator, which I still use - for the bits it couldn’t handle, and the level of control over final output was pretty well 100%. Ever since I’ve missed that precision (the days of tables were the worst), but it’s pretty well back now, and better still as we can dynamically adapt to different canvas sizes. Flexbox is really useful and consigns the most horrible hacks to the bin. Tfft. Shame about all the so-called ‘sharing’ leeches who are trying to monopolise the web atm - after all it’s just a communication channel like talking or writing, so why should anyone own it? Now we have better tools to get past their overpriced tat.

All things change with time. Some changes are better than others. :)

Flash will be around a little longer, but Facebook is a big shift toward its demise.

>>The beginning of the end.

I would have said the beginning of the end was in 2008 when Apple said "No" to Flash on the iPhone. But perhaps you're right. Perhaps that was the "end of the beginning" as Churchill said of El Alamein.... That was probably the highwater mark for Flash penetration.

November, 2015 - Adobe renamed Flash Professional in recognition of the fact that fewer and fewer people were using it for Flash animation (1/3 of all animations were in HTML5; no count of the number of people who just left and used another solution - in other words, 1/3 of what number?)

And now Facebook.... the beginning of the end (in Churchill's world, that would be D-Day, which might be about right).

Flash had a good run and it served it's purpose. It didn't age so well with daily security updates/vulnerabilities but it carried the web to HTML5.

Not a fan of HTML5 videos on Facecrook, they make clicking to pause the video open it on a modal, wildly obnoxious though at least now when you come across something useful you don't need a browser extension to save the source video and on top of that have it in some wonky Adobe format. I'll take two out of three.

I can't say I'll miss the constant stream of updates, warnings and failures Flash is responsible for on my computer. It was time.

It's still going to be around for a while, JS Harris, but the sooner it's dropped the better. Flash is one of those annoying things that causes crashes, and importantly, doesn't help with security issues.

At least if FB is not using it that's one fewer place to cause user problems.
