A fee based on viewership counts is how the anime service Crunchyroll works. A portion (the other part is Crunchyroll's) of the ad revenue and subscription fees are split based on what you watch. So, if you only watched a single show for the month, the portion that goes to the license holders would go to that single company. It seems to be working well on the whole as more companies are licensing their content to Crunchyroll (at least the ones who don't give an exclusive license to another company). Each season I see more shows on there.
