From the 30th of June, Google will stop allowing advertisers from uploading display ads built in Adobe Flash to its AdWords and DoubleClick Digital Marketing platforms. From that date, advertisers will only be able to upload display ads built in HTML5 instead. Advertisers currently using Flash ads are therefore being urged to update any new ads to HTML5 before this date, to ensure that they don’t miss out on advertising opportunities. From the 2nd of January 2017, all Flash ads will stop working on its AdWords and DoubleClick Digital Marketing platforms, meaning that old Flash ads uploaded before the 30th of June deadline will need to be updated to HTML5 before this second deadline. Google’s move away from Flash is due to the software’s infamous vulnerability to security problems.
