The feature reportedly allows users to send video clips, links, and text directly from YouTube's app.

The beta feature is being tested in Canada on iOS and Android, with a wider roll out expected later in the year.

Message in a bottle

In-app messaging could have big consequences for brands, content creators, and influencers.

By allowing brands to send direct messages to its audience, YouTube could boost engagement levels and offer a more personalised experience for viewers.

Something that would bring YouTube closer into line with fellow titan (and video rival) Facebook.
