The American sitcom Friends was created by David Crane and Marta Kauffman, and produced by Bright/Kauffman/Crane Productions in association with Warner Bros. Television Studios for NBC.
The series narrative follows six friends living and working in New York City: Rachel Green, Monica Geller, Phoebe Buffay, Joey Tribbiani, Chandler Bing, and Ross Geller played by Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry, and David Schwimmer respectively.
In Friends: The Stuff You've Never Seen, broadcast following "The One with Joey's New Brain" on February 15, 2001, Conan O'Brien hosted a light-hearted discussion with the main cast on the Central Perk set – the fictional coffee house which featured prominently in the series.
The two-part retrospective special The One with All the Other Ones was broadcast before the one-hour series finale "The Last One" on May 6, 2004, and features clips from past episodes and interviews with the cast.
The large spike in season 2 is for the double episode "The One After the Superbowl" which aired after Super Bowl XXX.
