Original network: NBC (1995-1996)
Moved to: CBS (1997-2005)
How it fared: After airing for a single low-rated season on NBC, the military procedural was saved from obscurity when CBS picked it up as a mid-season replacement the following year. The unconventional move proved a lucrative one for the Eye Network, as the show finished in the Nielsen Top 20 by its third season and remained a reliable performer until finally ending its run after nine seasons on the air. When all is said and done, "JAG"'s greatest legacy no doubt lies in its even more popular spin-off "NCIS," which itself spawned the Nielsen Top 10 hit "NCIS: Los Angeles" in 2009.
