Barter syndicated series may be seen on smaller, independent stations with small budgets or as short-term filler on larger stations; they tend not to be as widely syndicated as programs syndicated with a rights fee.With the growing availability of cable and satellite television channels as well as over-the-air digital subchannels, combined with a growing body of available post-syndication programming, a handful of specialty channels have been built solely or primarily to run former network programming which otherwise would no longer be in syndication.Very popular series running more than four seasons may start daily reruns of the first seasons, while production and airings continue of the current season's episodes; until approximately the early 1980s, shows that aired in syndication while still in production had the reruns aired under an alternate name (or multiple alternate names, as was the case with Death Valley Days) to differentiate the reruns from the first-run episodes.Few people anticipated the long life that a popular television series would eventually see in syndication, so most performers signed contracts that limited residual payments to about six repeats.Once a series is no longer performing well enough to be sold in syndication, it may still remain in barter syndication, in which television stations are offered the program for free in exchange for a requirement to air additional advertisements (without compensation) bundled with the free program during other shows (barter syndication is far more common, if not the norm, in radio, where only the most popular programs charge rights fees).The Program Exchange was once the most prominent barter syndicator in United States television, offering mostly older series from numerous network libraries.Since local television stations often need to sell more commercial airtime than network affiliates, syndicated shows are usually edited to make room for extra commercials.Often about 100 episodes (four to five seasons' worth) are required for a weekly series to be rerun in daily syndication (at least four times a week).
The episode is usually the "repeat" of the scheduled episode that was broadcast in the original timeslot earlier the previous week.
Reruns can also be, as the case with more popular shows, when a show is aired outside its timeslot (for example, in the afternoon).
In the United Kingdom, the word "repeat" refers only to a single episode; "rerun" or "rerunning" is the preferred term for an entire series/season.
It allows viewers who weren't able to watch the show in its timeslot to catch-up before the next episode is broadcast.
The term "rerun" can also be used in some respects as a synonym for reprint, the equivalent term for print items; this is especially true for print items that are part of ongoing series (such as comic strips; Peanuts, for instance, has been in reruns since the retirement and death of creator Charles M. In South Africa, reruns of the daily soap opera 7de Laan, and others, are called an Omnibus.
