In British football, there exists a 'Saturday TV football blackout law' which prohibits the broadcasting of live Premier League matches (the top tier of English football) between 2:45pm and 5:15pm on Saturday. Introduced in the 1960s, the intention behind this law is to minimize negative impacts on the attendance of lower league matches. For instance, if Manchester United played against Arsenal, proponents of the law thought that many supporters of lower tier teams will opt to watch that instead of go to the stadiums of their local clubs to watch lower tier matches live.
