Broadcast syndication is the practice of leasing the right to broadcasting television shows and radio programs to multiple television stations and radio stations, without going through a broadcast network. It is common in the United States where broadcast programming is scheduled by television networks with local independent affiliates. Syndication is less widespread in the rest of the world, as most countries have centralized networks or television stations without local affiliates. Shows can be syndicated internationally, although this is less common.

Three common types of syndication are: first-run syndication, which is programming that is broadcast for the first time as a syndicated show and is made specifically to sell directly into syndication; off-network syndication (colloquially called a "rerun"), which is the licensing of a program whose first airing was on network TV or in some cases, first-run syndication; and public broadcasting syndication.
