It looks like YouTube could be getting some new functionality soon. Polygon’s Nick Robinson spotted a new feature YouTube is testing, where you’ll get a small preview of a video when you mouseover the thumbnail.
This feature isn’t necessarily new, as it’s something that’s already been implemented over on YouTube Gaming. That said, it’s won’t be too surprising to see the mouseover preview on the entire YouTube platform. What we don’t know if this is just a test that a couple of random users are apart of or if this is actually rolling out right now.
There doesn’t seem to be any other users reporting seeing this type of functionality, so it’s likely just in the testing stage. It’s likely we’ll see it eventually, as it is something YouTube Gaming already has, we just don’t know when.
