In some countries, broadcast regulations referred to as "anti-siphoning laws" exist in order to ensure that coverage of major sporting events of national importance—often covering major events such as the Olympics, FIFA World Cup, and national team events in culturally-significant sports—are available on free-to-air, terrestrial television, rather than exclusively on pay television. Some larger events (particularly the Olympics) may be covered under rules allowing a portion of the event to be televised by a pay TV partner if a specific minimum of coverage is broadcast free-to-air, or if an extended highlights package is available on a delay to a free-to-air broadcaster.
