Adobe Flash Player has been plagued by security issues and instability, and finally the tide is turning against it. In July Mozilla blocked Flash on Firefox, and now Google is doing the same for Chrome, which will have an even bigger impact, since Chrome is a much more popular browser.
Google explained to ad customers:
To ensure your ads continue to show on the Google Display Network, please follow these steps before September 1:
1) Identify any Flash ads in your account that aren’t eligible for automatic conversion: https://goo.gl/I4186A
2) Convert these ads to HTML5: https://goo.gl/ZBq5DR
That's it. In one fell swoop Google is taking the step we've all been waiting for. And with other companies like Amazon on board, too, this might actually happen. Eliminating all Flash Player components will probably still be a little bit of a whack-a-mole situation for a while, but if we lean on each other and believe, anything is possible.
