I'm talking about reaching viewership thresholds, not gaining viewers.
Let's say your show is in 3 different sites and your total audience is 100 viewers across the 3 sites.
For monetization, Site A has a threshold of 100, Site B has a threshold of 75, and Site C has a site of 80.
In viewership numbers (remember, the total is 100), the video on Site A has 55 viewers, the video on Site B has 20 viewers, and the video on Site C has 25 viewers.
Due to the fragmentation of your audience, you failed to reach the viewership threshold on all three sites.
This is partly why regular TV/ Cable networks don't premiere new episodes on different channels.
