2006 United States broadcast TV realignment

The 2006 United States broadcast television realignment consisted of a series of events that resulted from the January 2006 announcement that the country's two "second-tier" television networks, UPN and The WB, would both cease operations. The two networks respectively shut down on September 15 and 17, and their operations were transferred to a new joint-venture "fifth" network, The CW. Meanwhile, Fox Television Stations (which owned several UPN-affiliated stations in large cities that were blocked from affiliating with The CW) signed up with MyNetworkTV, a new network owned by then-parent company News Corporation's Fox Entertainment Group.
