WCWB[]
1998–2006[]
WPTT-TV dropped its UPN affiliation on January 15, 1998 (which moved to WNPA-TV, UHF channel 19; now WPKD-TV) and affiliated with The WB as part of a wide-ranging affiliation deal that saw Sinclair Broadcast Group's owned and managed UPN affiliates and independent stations switch to the network. The station also changed its call sign to WCWB (for "C, or See, the WB") on the 13th, two days before the switch, to reflect its new affiliation. The WCWB calls had previously been used by the NBC affiliate in Macon, Georgia (now WMGT-TV); the WPTT calls were later used by a radio station on 1360 AM in Pittsburgh, which later changed its callsign to WMNY in 2008.
WPMY[]
2006–2015[]
WCWB, meanwhile, later decided to affiliate with MyNetworkTV, another new network owned by News Corporation's Fox Entertainment Group and 20th Television divisions. On April 17, WCWB changed its call letters to WPMY to reflect the new affiliation while keeping the "Pittsburgh's WB22" until the WB's end.
WPNT[]

On May 19, 2015, WPMY quietly changed its call letters to WPNT for the landmark "Point" confluence of the Ohio, Allegheny and Monongahela rivers in downtown Pittsburgh, which previously appeared in the market nearly three decades earlier on FM 92.9, now WLTJ. Coincidentally, WLTJ also shares its transmitter facilities with WPGH-TV and WPNT.
2015–present[]
On September 1, 2023, due to Paramount dropping The CW from its stations, WPNT became a CW affiliate, replacing Paramount-owned WPCW while retaining MyNetworkTV as a secondary affiliation.
