The term 'reruns' generally refers to the repeating of a previously aired television program. However, there are a few other ways to refer to this phenomenon in a variety of contexts. One popular synonym for 'reruns' is 'repeats,' which can be applied to anything that is shown or done again. Another similar term is 'rebroadcasts,' which carries the same meaning but is primarily used for media like radio or podcasts. In a more general sense, 'recapitulations' could also be used to describe a summary or repetition of a previously presented idea or concept.
