Internet audiences don't like watching commercials.
Even more so when the commercial is not for the product he doesn't want to see.
Everyone's attention is extremely reduced.
5 is the maximum limit of a person's attention span to watch a commercial.
This is the model that has worked on YouTube and should be implemented on Twitch.
30-second commercial is not acceptable for users here, everyone ends up running away from the broadcast.
