The biggest example is how it works in America for the NFL. Clubs (or franchises if you prefer) stream their own matches for a fee whilst also selling out their ridiculously large stadiums. Plus, their ticket prices are at least 3 times as much as we pay at Sixfields.
They stream the NFL games because they sell out the stadiums. With only nine homes games per season for teams that dont make the play-offs and a far bigger catchment area it's not a good example.
