YouTube tests letting users share and talk about videos in group message threads within the app, which others can be invited to join
Context & Ripple Effects
This 2016 test is the seed of a feature arc the coverage traces end to end: the group-chat experiment first shipped broadly in Canada in early 2017, then reached all Android and iOS users with 30-person groups that August, before extending to the web in 2018.
The reason it matters is what came after: YouTube quietly discontinued Messages in September 2019, then years later rebuilt in-app messaging around 1:1 video sharing — making this original test the first attempt in a cycle of trying to keep the 'send a video to a friend' moment on-platform.
First-order effects
- Users testing the feature can share and discuss videos in invite-able group threads without leaving the app, replacing the copy-link-to-iMessage-or-Messenger flow that currently exports YouTube traffic to other companies' chat surfaces.
Second-order effects
- Apple's iMessage becomes the direct competitive reference point — YouTube followed this test with an iMessage app extension for iOS, signaling it wants to meet sharers inside Apple's messenger even while building its own threads.
Third-order effects
- The full arc — launch, expansion, 2019 shutdown, later relaunch — shows how hard it is for a video platform to grow a social graph from scratch against entrenched messengers, and why platforms keep retrying anyway: whoever owns the share layer owns the referral loop.
The trend: Video platforms keep attempting to internalize peer-to-peer sharing rather than cede the referral layer to OS-level messengers, with YouTube's repeated launches and retractions marking the pattern's clearest case.
