Earlier this year in March, YouTube started testing a new picture-in-picture (PiP) mode for the desktop version of the service, which allowed users to watch videos in a miniplayer in the bottom right corner of their screens, while searching for other videos or navigating to the homepage. The feature now seems to be rolling out to some users and a couple of people in our office have already received it.
Since the company tested the feature with a really small audience back in March, we can’t be sure if this rollout is part of a larger test audience. Nonetheless, the fact that the feature is rolling out to more people means that it’ll soon be available for all users.
