10 TV series that changed networks: 'Buffy the Vampire Slayer,' 'Southland,' 'Futurama'
Original network: ABC (1989 - 1997)
Moved to: CBS (1997-1998)
How it fared: A spin-off of "Perfect Strangers" that focused on an African-American family in Chicago, "Family" was a popular feature of ABC's "TGIF" lineup, where Urkel and co. earned a devoted following. Tensions between the show's producers and the network ended with the show and "Step By Step" moving to CBS, where Friday night lightning failed to strike twice.
