MyNetwork TV
On January 24, 2006, it was announced that The WB and UPN would merge into a new network, The CW. As a result of this merger, WPCW (the former WNPA, and a former UPN O&O) became the CW affiliate, and on September 5, Channel 22 began carrying the Monday-through-Saturday MyNetwork TV block from Fox. On April 17, WCWB changed its call letters to WPMY to reflect this (plugs for MyNetwork TV and The Tube now use the WPMY calls). On August 14, 2006, WPMY rebranded itself as My Pittsburgh TV to promote MyNetwork TV, also different cable companies, carry WPMY on different channels. (The official moniker is "My Pittsburgh TV", even though the logo reads like "My TV Pittsburgh".) Unlike many other former WB affiliates switching to MyNetwork TV, WPMY continued to air The WB's primetime schedule in the late night hours until September 18, 2006, when The CW launched.
The station no longer uses the "22" moniker in any form on the station except for FCC-mandated station identification purposes. With Comcast being the dominant cable provider in the Pittsburgh region (Armstrong Cable also has systems in Armstrong, Butler, & Indiana counties, and a very small portion of Lawrence County) the station is commonly on channel 10 on Comcast systems, and thus WPMY is often advertised on-air as "Comcast channel 10", somewhat taking a virtual channel route.
