NBC's Tonight is a Saturday evening political commentary program that has aired live from 7:00 to 8:00 every Saturday night on NBC since 1982, and has been aired on NBCable as well since 1999. The show was initially the successor program to The Ronald Reagan Show, which ran in the 5:00 PM Friday timeslot on NBC from 1958 to 1981, when the network decided to move the show to two hours later and try to revolutionize a "weekend primetime" slot. The gimmick was a moderate success, with the program, redubbed Tonight with Ronald Reagan following the switch, dominating the 7:00 PM Saturday slot, albeit due to uninspired competition.
