YouTube is banning advertisements about a handful of topics from its highly visible masthead ad unit.

Political and election ads will no longer be accepted for placement in that unit, which is a banner running across the top of the video platform’s homepage. The covetable — and pricey — spot is “the most prominent Google advertising placement available to advertisers,” the company said.

Ads relating to alcohol sales, gambling — such as sports betting and casino games — and prescription drugs will also be banned, per the spokesperson. Axios first reported the change.
