Google has said it's now going to show videos with fewer intrusive ads, as defined by the Coalition for Better Ads "Better Ads Standards". These include:-
Long, non-skippable pre-roll ads or groups of ads longer than 31 seconds that appear before a video and that cannot be skipped within the first 5 seconds.
Mid-roll ads of any duration that appear in the middle of a video, interrupting the user’s experience.
Image or text ads that appear on top of a playing video and are in the middle 1/3 of the video player window or cover more than 20 percent of the video content.
The Coalition says that site owners should stop showing such ads to visitors within four months, and Chrome will stop showing all ads on sites anywhere where these disruptive ads are shown.
Google also says that YouTube will follow the standards, too.
