I would like to suggest a feature aimed at improving the ecosystem of official tournament broadcasts and authorized co-streams.

Currently, when an official esports broadcast (such as League of Legends, CS, or other tournaments) allows co-streaming by approved creators, the viewership is split across multiple channels. For example, if an official broadcast grants permission to a co-streamer, a large portion of viewers may watch through that co-stream instead of the official channel. As a result, the official broadcast does not fully reflect the total audience it is actually reaching.

My suggestion is to introduce a "Shared Viewership" system for authorized co-streams. In this system:

The official broadcast would act as the “primary” or “parent” stream.
Authorized co-streamers would be linked as “child” streams.
Viewership from co-streams would count both toward the co-streamer’s channel and be aggregated into the official broadcast’s total view count.

This would allow:

Tournament organizers to accurately measure total audience reach.
Co-streamers to continue growing their own communities.
A stronger partnership between official broadcasts and creators.

Optionally, Twitch could visually indicate that a stream is an “official co-stream” and display combined viewership metrics across all linked streams.

I believe this feature would strengthen the esports ecosystem on Twitch and provide more accurate data for organizers, sponsors, and viewers alike.

Thank you for your time and consideration.
