“Quantum Leap,” which has seen its ratings increase by 58% since returning to the NBC schedule March 6, has been renewed for a fourth season, the network announced Friday.

The fantasy drama, in which Scott Bakula stars as time-traveling scientist Sam Beckett, has averaged a 12.3 Nielsen rating (about 11.4 million households) in its four most recent telecasts.

Also receiving renewal notices Friday were NBC’s “Law & Order,” and ABC’s “Doogie Howser, M.D.”
