UPN eventually outbid The WB for the shows and aired them together on Tuesday nights until Roswell ended its run in 2002; Buffy ended its run the following year. In January 2002, Viacom President and COO, Mel Karmazin restructured the network, resulting in UPN being taken out of the ownership of Paramount Television, and being placed under the oversight of CBS Television, with CBS President Leslie Moonves being given responsibility for the network.
