Saturday Night Live 40th Anniversary Special

"Saturday Night Live 40th Anniversary Special" (also billed as "SNL40") is a three-and-a-half-hour prime-time special that aired on February 15, 2015, on NBC, celebrating Saturday Night Live's 40th year on the air, having premiered on October 11, 1975, under the original title NBC's Saturday Night. The special was produced by Broadway Video and directed by then-series director Don Roy King. This special generated 23.1 million viewers, becoming NBC's most-watched prime-time, non-sports, entertainment telecast (excluding Super Bowl lead-outs) since the Friends series finale in 2004. It is the third such anniversary special to be broadcast, with celebratory episodes also held during the 15th and 25th seasons.

The special was preceded on NBC by an hour-long SNL 40th Red Carpet Live, hosted by Matt Lauer, Savannah Guthrie, Carson Daly and Al Roker, who interviewed past hosts, current and previous cast members, and musical legends who had previously performed on the show.
