It premiered on NBC, a terrestrial television network, on October 11, 1975 under the title "NBC's Saturday Night".  The show often satirizes contemporary American popular culture and politics.  "Saturday Night Live" features a two-tiered cast: the repertory members, also known as the "Not Ready for Prime-Time Players," and newer cast members, known as "Featured Players."  Each week, the show features a host, often a well-known celebrity, who delivers an opening monologue and performs in sketches with the cast.  A musical guest is also invited to perform several sets (usually two, and occasionally more).
