Google has announced that they will begin moving heavily towards the use of HTML5 in Chrome next month, stating that Chrome will eventually end up with HTML5 as the default experience once the browser hits version 55 this December. HTML5 has been designated as the replacement for Flash on the web for years, and Google's Chrome for Android browser has stopped supporting Flash quite some time ago. Having said that, Google's statement today does not mean that Flash will not be supported once these default changes take place in a few months, it does however mean that most sites will switch to HTML5, and those that still only support Flash will simply end up feeding a prompt for users to install Flash once that site is visited.
Google notes that many sites already implement HTML5 on their web pages which offers up faster page load times in addition to a handful of other benefits like improvements to security, as well as the browser having to consume less power when the user is browsing the web. With this being the case it shouldn't be too shocking that Google wants to shift towards using HTML5 as a default experience in Chrome as it mostly only benefits the users as well as the websites.
In addition to moving over to HTML5 as a default experience later on this year, Google notes that next month is when they will begin to start blocking Flash that works "behind the scenes," which Google states is mostly used for page analytics support. According to Google, more than 90 percent of website use this kind of Flash, and it's only making things slower for the end user, which is a big reason why Google wants to move away from it. As stated, this begins next month with Chrome 53. When December hits and HTML5 becomes the default experience in Chrome, these changes will apply to games and videos. Since websites that support Flash exclusively will prompt users to download and install Flash upon visiting those web pages, those site will not be affected by the change that Google is setting in motion.
