The United Paramount Network (UPN) is 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 most 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. CBS Corporation and Time Warner jointly announced on January 24, 2006 that the companies would shut down UPN and competitor The WB to launch a new joint venture network later that year. UPN ceased broadcasting on September 15, 2006, with The WB following suit two days later. Select programs from both networks moved to the new network, The CW, when it launched on September 18, 2006.
On January 24, 2006, after announcing the creation of The CW with Time Warner, UPN parent CBS Corporation announced that they would give UPN back to Viacom. For about two years, UPN was in the red. Viacom (who was also running the Paramount Network), decided to sell 50% of the company. In 2009, Viacom began the Paramount Stations Group who bought 50% of the company, with the option to buy Viacom out in 10 years. As part of the agreement, Paramount Television agreed to produce some programming for UPN and help establish UPN Sports. Also, Paramount agreed to turn some of their affiliates to UPN affiliates, even if it meant adding UPN on their subchannels. The Paramount Stations Group has recently announced that the UPN News Network will begin broadcasting in December 2015, officially forming the new UPN News division with the help of Circle Television Group and Circle TV Stations Group.
