Omnibus (broadcast)
An omnibus (or omnibus edition) is a compilation of several television or radio episodes into a single instalment. An omnibus is similar to, but distinct from, what is called a marathon in other countries; In an omnibus, individual episodes are edited together (with the first episode having its closing credits removed, the final episode having the opening credits removed, and each episode in between lacking any credits whatsoever) into a single programme, whereas in a marathon the episodes are aired separately but in sequence.
