Adobe ends mobile Flash development, will focus on HTML5
Adobe will no longer update its Flash plugin for mobile browsers, though it will continue to issue security updates and bug fixes. The company issued a statement to developers conceding that "HTML5 is now universally supported on major mobile devices, in some cases exclusively," adding "that makes HTML5 the best solution for creating and deploying content in the browser across mobile platforms."
