Adobe will instead be focusing on HTML5, which it sees as the future. This is big news and potentially great news for the mobile Web:
However, HTML5 is now universally supported on major mobile devices, in some cases exclusively. 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.
I have long not been a fan of Flash. It never ran particularly well on OS X or Linux. It ran on very few mobile devices and usually ran very poorly. It was a buggy runtime that caused a lot of Web browser crashes. It was full of security exploits.
I no longer have Flash installed on my default Web browser on the desktop. My browser and computer runs much faster this way. Crashes are a thing of the past.
Many websites still rely heavily on Flash, particularly for video. With mobile growing so fast and becoming so important, websites can no longer provide just Flash. They need to provide fallbacks to other technologies that will work on mobile. Every time I go to a news website and see video that won’t work on my iPad or iPhone, I shake my head. There really is no excuse anymore.
Even Adobe says you should move on.
