YouTube wrote in to let us know that our back-of-the-envelope math on its partner program had a fatal flaw, because the site pays different partners different CPMs.
We had used one partner’s example of making $1600 for about 2 million views to assume that YouTube’s just-announced figure of $1 million paid out to users was in exchange for about 1.25 billion views. However, different partners command different audiences, a YouTube spokesperson said, so they receive different ads that are worth different CPMs.
YouTube also said that it has “many more” than 100 user partners. We had counted based on the most-subscribed partner list, but it turns out that list is only limited to the top 100. However, the site would not disclose the total number of partners in its user partner program.
