What is it about league that people love watching it so much?

It seems like ever since season 3 every year the league worlds have been an insane event. Don’t quote me but I think in terms of number of viewers it’s sky high. Fortnite had a stint where it got ahead but it seems league has reclaimed it again. On the other hand I don’t think league gets as much play time compared to these other games. These are all feelings of being in the community for so long, please feel free to correct my opinions.
