10 TV series that changed networks: 'Buffy the Vampire Slayer,' 'Southland,' 'Futurama'
'Law & Order: Criminal Intent'
Original network: NBC (2001-2007)
Moved to: USA (2007-2011)
How it fared: With its normally-solid ratings dipping severely in its sixth season (most likely due to a time-slot change), NBC shipped "Criminal Intent" over to its sister cable network USA - a cost-sharing move that kept the "Law & Order" spin-off on the air for four more seasons (the arrangement early on included airing the USA episodes on NBC at a later date). The show finally left the airwaves in 2011, its audience greatly diminished from its glory days as a Top 20 ratings champ.
