Codename: Kids Next Door

Codename: Kids Next Door is an American animated spy fiction television series created by Mr. Warburton for Cartoon Network. It was produced by Curious Pictures with assistance from Cartoon Network Studios. The series follows the adventures of a diverse group of five children who operate from a high-tech treehouse, fighting against adult and teenage tyranny with advanced 2×4 technology. Using their code names (Numbuhs 1, 2, 3, 4, and 5), they are Sector V, part of a global organization called the Kids Next Door.

The series' pilot premiered on Cartoon Network in mid-2001 as part of The Big Pick II, a special broadcast event showcasing 11 pilots for different series. The winner of a viewers' poll by Cartoon Network would decide which pilot would be greenlit to be a full series. After winning the poll, the series premiered on December 6, 2002, and concluded on January 21, 2008, after six seasons and 81 episodes. Two television films were broadcast: Operation: Z.E.R.O., which aired in 2006, and Operation: I.N.T.E.R.V.I.E.W.S., which aired as the series finale in 2008. A special half-hour crossover episode with fellow Cartoon Network series, The Grim Adventures of Billy & Mandy, aired in 2007.

Spin-off media include two video games, Operation S.O.D.A. and Operation V.I.D.E.O.G.A.M.E., as well as a trading card game, comic books, and DVD releases. Codename: Kids Next Door has also appeared in DVD anthologies and compilation video games from Cartoon Network.
