A television revival is an attempt to revive a defunct series by producing new episodes created for broadcast. Network executives may decide to attempt to revive a television program when they feel that a market once again exists for it.
Revival is one of several programming strategies television networks employ to capitalize further on successful programs; among the other methods are spin-offs, cast reunions, and television movies based on the original program.
Unlike spin-offs—in which a television network creates a new program around one or more familiar, popular characters from a different program—a revival involves the reintroduction of most, or at least many of the original program's storyline, characters, and locales. Revivals should also be differentiated from remakes and continuity reboots where the characters and/or central concepts are retained, but the story starts over from the beginning again. Revivals differ in that they pick up either from where the older show left off, or at some time after that point.
An example of a successful revival outside of the U.S. is the 2005 British science fiction series Doctor Who.
A notable example of an unsuccessful U.S. revival is the 1968 CBS series Blondie (a remake of the 1957 NBC series), which only lasted for half of a season (13 episodes), despite being based on an extremely popular and durable comic strip, and a marketing tie-in with a series of paperback reprints of Blondie strips starting with the 1930s originals. The 1957 series only lasted one complete season (26 episodes).
