In the United States, team sports are broadcast by networks usually only in "game of the week" or championship situations, except for the NFL (see NFL on television) and motorsport. Other sports are broadcast by sports channels, and are limited by who can view them based on various rules set by the leagues themselves, resulting in blackouts. These limitations can be legally overlooked by purchasing out-of-market sports packages, such as MLB Extra Innings or NFL Sunday Ticket. Regular season games involving local teams (except the NFL) may also be viewed on those local stations or regional sports channels that have a contract to broadcast that team's games.
