YouTube has begun to crack down on ad-blockers across the globe in its latest campaign, according to Christopher Lawton, YouTube's communications manager.
While only certain users were last month nudged to disable ad-blockers or subscribe to YouTube Premium, now, all users with ad-blockers are prompted to whitelist or disable them.
Commenting on the campaign, Lawton stressed that ad-blockers violate YouTube's terms of service and prevent support to creators and access to content.
Intensified efforts are shown through pop-up notifications, preventing ad-blocker users from video playback unless they whitelist or disable it.
YouTube, which initially experimented with limiting video access for ad-blockers in June, now expanded its efforts globally after registering a decline in ad revenue for the past three quarters.
YouTube has tweaked ad delivery, adding unskippable 30-second TV app ads and longer but less frequent ad breaks. These changes aim to promote YouTube Premium, offering an ad-free experience for $13.99 per month.
However, a recent price hike and the discontinuation of Premium Lite last month might affect its appeal to some users.
