Today is the day where Google AdWords will no longer show Flash based AdWords ads on Chrome.
Google posted this to their what's new page yesterday, "AdWords will stop showing Flash ads on Chrome starting September 1, 2015."
Google also posted yesterday on Google+ methods to migrate your Flash ads to HTML5.
Google said:
Helping to ease the transition to HTML5As browsers change the way they support Flash, HTML5 is becoming the de facto language for building display ads. To support this transition to HTML5, we’re excited to announce a series of updates to Google Web Designer [http://goo.gl/IMN8jo] that help make it easier to build HTML5 ads, including the launch of responsive design features.
Google is trying to move away from Flash ads for a long long time now. Earlier this year we covered a tool to convert your Flash ads to HTML5 provided by Google.
In any event, today, you should no longer see Flash Google ads on Chrome.
