In the coming quarters, all major browsers, including Chrome, are phasing out the use of Flash technologies in favor of HTML5. HTML5 is not only available on more devices, but also offers improved security, reduced power consumption and faster page load times for users.

We began our transition to HTML5 with display ads across Google and DoubleClick back in 2015. We are now continuing that transition by shifting video ads in DoubleClick Digital Marketing, DoubleClick for Publishers, DoubleClick Ad Exchange and the Google Display Network to HTML5 over the next few quarters as follows:

  • Starting April 3rd, 2017, new Flash video ads will no longer be able to be uploaded into DoubleClick Studio, DoubleClick Campaign Manager, DoubleClick Bid Manager, DoubleClick for Publishers or AdWords.
  • Starting July 3rd, 2017, Flash video ads will no longer be able to run through DoubleClick Campaign Manager, DoubleClick Bid Manager, DoubleClick Ad Exchange, DoubleClick for Publishers or AdWords. Additionally, our Active View and Verification tools for video will no longer use Flash.

Transition timeline for HTML5 Video


It’s important to begin updating your ads and websites to HTML5 technologies in preparation for these dates. We fully support HTML5 Video across DoubleClick and AdWords and provide the tools to ensure advertisers and publishers can easily migrate all video ads to HTML5.

For guidance and best practices to help your team with this transition, see Chrome one-sheeter, visit the DoubleClick help center or contact your DoubleClick sales representative.
