It's an older feature that YouTube has been releasing two months ago.
The YouTube comes with a new feature named: Premiere.
The goal for YouTube users is to be able to organize and distribute video content on a specific date and on a specific target.
What's interesting about it?
Once a premiere is scheduled, a shareable and public watch page is created. This page shows the video metadata, including title, description, and thumbnail. In addition, the video will eventually premiere on this watch page URL. Viewers can start interacting through Comments and Live Chat before and during the premiere.
A very good part for the target is raising money for the Premiere feature.
