NBC qubo

NBC qubo is an American children's television block that debuted on October 7th, 2002, replacing the network's prior TNBC Saturday morning lineup. NBC qubo was announced after NBC decided to end TNBC after its struggling ratings. The block relaunched as a more simplified version of itself on September 9th, 2006, also changing its name to Qubo on NBC.

History
In December 2001, NBC declined to go into a contract with the Discovery Kids cable channel, stating to relaunch its TNBC block independently.
