A rerun is a repeat transmission of a program that has already been broadcast. The term most often refers to shows on television but also applies to programs on radio. A rerun may be identical to the original airing or slightly edited for time, content, or advertising requirements. Synonyms include repeat, encore, or rebroadcast.

Characteristics and how they are scheduled

Reruns appear for a variety of reasons: to fill a schedule slot, introduce an older program to new viewers, or to monetize a series after its initial run. They can be contracted as part of syndication packages, streamed on demand, or placed in a daily "strip" where a program airs at the same time each weekday. Rights, advertising arrangements, and regional regulations shape how and when reruns are shown.

Common uses and significance

Broadcasters rely on reruns to reduce production costs while maintaining audience continuity. Networks and stations earn revenue by selling rerun rights to other channels or streaming services. For viewers, reruns offer accessibility for missed episodes, a chance to rewatch favorites, and a way to introduce classic series to new generations. In some cases, reruns prolong the cultural life of a show and influence syndication value.

History and development

Repeating broadcasts dates back to early radio when popular programs were rebroadcast to reach wider audiences. With the rise of television, reruns became an industry staple: networks used them to stabilize schedules and create profitable syndication markets. The advent of cable, home video, and streaming shifted the practice from scheduled repeats to on-demand availability, but the basic concept of rebroadcasting content remains the same.

Distinctions and notable points

  • Rerun vs. rebroadcast: a rerun usually denotes a repeat of a previously scheduled episode, while rebroadcast can refer to an additional airing of live events or one-off programs.
  • Edited reruns are common; time constraints or content standards may lead to shortened or censored versions.
  • Syndication after an initial run can be a major revenue stream for producers and rights holders.

Understanding reruns involves broadcast practice, legal rights, audience behavior, and changing distribution technologies. Whether on traditional television slots, public radio repeats, or modern streaming libraries, reruns remain a core part of how audiovisual content is reused and circulated.
