Definition

A broadcast of a previously aired television or radio program, shown again after its original airing. Reruns allow networks to fill programming schedules economically and give audiences a second chance to watch shows they may have missed.

Example Usage

During the summer, most networks just show reruns of popular shows from earlier seasons.

Origin

The practice emerged in the 1950s as television networks sought cost-effective ways to maintain daily programming schedules.

Fun Fact

Some shows have become more popular in reruns than in their original broadcasts; 'Seinfeld' generated massive syndication revenue and introduced the show to millions of viewers who never saw it air on NBC.
