In American television, prime-time TV series, episodes were originally self-contained so that they might be shown in any order, especially in re-runs. The cliffhanger technique tying together episodes ''within'' a season only became popular with the introduction of continuity in the 1980s in shows such as [[Hill Street Blues]]. Season-end cliffhangers encourage viewers to return after the summer hiatus. However, if the show is abruptly cancelled, this means that the plot remains permanently—and frustratingly—unresolved. | In American television, prime-time TV series, episodes were originally self-contained so that they might be shown in any order, especially in re-runs.
