Just a week after Amazon announced its plan to stop its support for Flash ads starting September 1st, Google also decided on that same date as the day its Chrome browser will block auto-playing on all Flash content that isn’t “central to the webpage” – i.e. the Flash-based ads.
What Brands Should Do
Due to Flash’s long-standing security problems, Google’s AdWords network already automatically converts most Flash ads into the more secure HTML5 format. As the industry continues to move toward HTML5, brands would be wise to make the switch sooner than later, both for ads and for product demo videos.
