As HTML5 gradually becomes the standard for mobile content interactivity on the Web, Adobe’s Flash platform is on its way out as a mobile browser experience. Adobe confirmed as much in a blog post today following ZDNet’s scoop that the company was pulling the plug on Flash Player development for browsers on mobile devices.

You’ll recall that Apple famously snubbed Adobe by deciding not to support Flash in its iOS, instead pinning future development growth on the emerging HTML5 standard for its open, rather than proprietary, development support. As of now, Adobe has for the most part come around to the same conclusion.

"HTML5 is now universally supported on major mobile devices, in some cases exclusively," says Danny Winokur, Adobe vice president and general manager, interactive development, in the post. "This makes HTML5 the best solution for creating and deploying content in the browser across mobile platforms. We are excited about this, and will continue our work with key players in the HTML community, including Google, Apple, Microsoft and RIM, to drive HTML5 innovation they can use to advance their mobile browsers."

Going forward Winokur says Adobe will increase its investments in HTML5 while allowing developers to build native apps using Adobe AIR for all the app stores. In the mobile world, Flash Player 11.1 for Android and BlackBerry Playbook will be the last version.

The Player will live on in the desktop environment, specifically in gaming and higher quality video. "We are already working on Flash Player 12 and a new round of exciting features which we expect to again advance what is possible for delivering high definition entertainment experiences," says Winokur.
