The United Paramount Network (UPN) was an American broadcast television network that launched on January 16, 1995. The network was originally owned by Chris-Craft Industries and United Television; Viacom (through its Paramount Television unit, which produced some of the network's series) turned the network into a joint venture in 1996 after acquiring a 50% stake in the network, and subsequently purchased Chris-Craft's remaining stake in 2000. In December 2005, UPN was spun off to CBS Corporation when Viacom split into two separate companies.
On September 6, 1999, Disney launched a children’s programming block named Disney's One Too, which served as a replacement to the network's previous programming block, UPN Kids. The programming block lasted until 2003 (3 years before the network’s closure). Some of the programming were shows that were broadcast on the ABC programming block, Disney's One Saturday Morning.
