Adobe said it will work with Facebook as well as Unity Technologies and Epic Games to help developers migrate their games. Now, however, only 17% of PC and Chrome users visit websites with Flash, and that percentage "continues to decline".
Content creators are being urged to transition to newer, open formats such as HTML5, WebGL, and WebAssembly. The company has announced plans to stop updating and distributing the Flash Player by the end of 2020. Sometime in mid-2018, sites using Flash will need explicit user permission to run every time the browser is restarted.
One reason for Adobe ending Flash is because it's a battery hog. Microsoft will do similar with Microsoft Edge and Internet Explorer, again disabling by default by 2019.
By the end of 2020, we will remove the ability to run Adobe Flash in Microsoft Edge and Internet Explorer across all supported versions of Microsoft Windows. "As developers shifted their efforts from web to mobile. and to the iPhone in particular, Apple's decision to deny Flash support on iOS resulted in native mobile development becoming more popular than Flash-based RIA development". Adobe dropped support for Flash on mobile devices in 2012. Following many years of denial, Adobe has finally admitted today that it's now time to let it go. Internet Explorer continues to allow Flash.
"Adobe will continue to support Flash on a number of major OSs and browsers that now support Flash content through the planned EOL", it said.
Adobe is killing Flash, the software that millions used in the early 2000s to play web games and watch video in their web browsers. In addition, other Adobe apps that previously supported "Export to Flash" features, now come with "Export to HTML5" options instead. Specifically, for Internet Explorer and Microsoft Edge, Microsoft will gradually phase out support for Flash over the next few years, culminating in dropping support entirely in 2020.
It's a move that has been a long time coming-Apple famously left out support for Flash from the iPhone, which portended its inevitable demise nearly a decade ago.
Now, if people install Flash onto their Macs, Flash will still remain "off by default". Three years may sound like a lot of time when killing a technology, but Adobe says that entire businesses are built around this technology and will require security patches until they are ready to move on.
