Google Display Ads Going All-HTML, Will Ban Flash In 2017 (arstechnica.com)
Google has announced its plan for display ads to go 100% HTML 5, in hopes of reaching the widest possible audience across screens. Starting on June 30, 2016, Google will no longer accept new Flash display ads from advertisers. And on January 2, 2017, even old Flash display ads will be blocked. This move comes as no surprise, as Google has been nudging its advertisers to stop using Flash. In fact, Google is not the only one moving away from Flash in favor of HTML. Steve Jobs hated Flash, and even Adobe itself has dropped Flash for Adobe Animate.
The downside here is that means you can't just get rid of CPU intensive ads by disabling Flash.
Like the HTML5 video tag, that was supposed to free us from evil Flash, but just brought forth the unblockable autoplaying autoloading multimegabyte video ad, this isn't as great a piece of news as it might seem...
You are not alone. This is not normal. None of this is normal.
I've blocked them by the simple expedient of, when my browser flashes the message "Could not display content because your flash player is out of date. Update?" clicking "go away".
