The show’s premiere was hosted by George Carlin on NBC on
October 11, 1975, under the original title NBC’s Saturday Night.
The topical comedy sketch show featuring Chevy Chase, John
Belushi, Dan Aykroyd, Gilda Radner, Garrett Morris, Jane Curtin
and Laraine Newman, made its debut on NBC.
The 90-minute program, which from its inception has been aired
live from Studio 8H at Rockefeller Center, included a different
guest host and musical act each week. The opening sketch of
each show ends with the saying… “Live from New York, It’s
Saturday Night.”
