YouTube is starting to test a new Collaboration feature. Creators can add collaborators to their video, which then allows their content to be recommended to each other's audiences. YouTube says it's currently testing it with a small group of creators.

YouTube has fully launched Collabs, making it available to users on Android and iOS devices.

YouTube revealed Shorts are being watched by over 2 billion logged-in users monthly, an increase from last year's 1.5 billion users.
