The Ofcom Code on Sports and Other Listed and Designated Events regulates that coverage of certain major sporting events (known as "Category A" events, covering certain major domestic events and major international competitions such as the Olympics and FIFA World Cup) must be broadcast primarily on a free-to-air channel (but can share coverage with pay channels), while certain events known as "Category B" events can be shown on pay channels, but supplemental coverage (such as highlights or a delayed broadcast) must be provided by a free-to-air channel.
