You must have missed the 500 million IPL viewers turning away from cricket because opposition players sometimes have a laugh with each other.
Darts rapidly increasing in popularity? Fake news. Nobody's interested because the players are too friendly during matches.
And as for PL football. A sharp decrease in interest because of all the hugging before and after matches, discussions on the pitch, subs from opposition sides having conversations whilst warming up, managers sharing a joke etc.
Or maybe they just take no notice because it happens everywhere.
