FIFA demands from the countries who are hosting the world cup, to finance the mandatory fanfests. This is where the public who cannot afford tickets to the games can watch the games in an open environment. There are 12 host cities for the cup and all of them must host these. FIFA has gotten some cities to sign the contracts, but not all. They are prepared to sue if the host cities who haven’t signed yet don’t throw the fest.
