The decline of Flash is well and truly underway. Media publishers now have no choice but to start changing the way they bring content to the web. Many of them are not thrilled about the proposition (change is scary), but it will almost certainly be better for all of us in the long run. "By switching their platform to HTML5, companies can improve supportability, development time will decrease and the duplicative efforts of supporting two code bases will be eliminated. It will also result in lower operating costs and a consistent user experience between desktop and mobile web." This is on top of the speed, efficiency, and security benefits for consumers. "A major concern for publishers today is the amount of media consumption that's occurring in mobile environments. They need to prioritize providing the best possible experience on mobile, and the decline of Flash and movement to HTML5 will do just that, as Flash has never worked well on mobile."
