Even though it isn't without controversy, Brave browser has this exact feature through use of its BAT token [1].

Basically, you earn BAT either by directly depositing money into your wallet, or by viewing "privacy respecting ads" (herein lies part of the controversy), which let you earn 70% of the ad revenue as BAT. These tokens are then distributed over the content creators who have signed up for the program. The exact distribution depends on how much attention you gave each creator.
