the station operating. However, he quit on May 6 after concluding the load of working 18-hour days was "too much," and WPTJ went silent. Return as WTWB-TV (1994–1997) Meanwhile, over in Pittsburgh, Venture Technologies Group had signed on low-power station W29AH (channel 29) in 1989 with the Video Jukebox Network, later known as The Box. However, five years later, Venture saw opportunity. Pittsburgh was the largest market without a signed affiliate of The WB, and it snagged the affiliation for its low-power station. At the same time, Venture purchased the silent WPTJ at a bankruptcy auction for less than $1 million. Channel 29 became WTWB-LP and then WBPA-LP, while channel 19 was given the new call letters WTWB-TV and plans were announced for the two to form a simulcast. On July 27, 1996, Venture reactivated the channel 19 facility under the WTWB-TV calls, operating from a new transmitter on Laurel Mountain west of Jennerstown. However, cable systems in Pittsburgh were not required to carry channel 19 because it was licensed to Johnstown, located in a separate media market. As a result, after claiming that Johnstown–Altoona could not support five TV stations, Venture won permission to move WTWB-TV's city of license to Jeannette, an eastern suburb of Pittsburgh. Since WTWB-TV was now a Pittsburgh-market station, Venture could now invoke must-carry protection. As WNPA (1997–2006) By the time WTWB-TV had been approved to move to Jeannette, however, more than the city of license was changing. Sinclair Broadcast Group secured a group deal with The WB to change several of its stations to that network, including WPTT (channel 22), which became WCWB. Just as cable systems in the Pittsburgh metro area began adding channel 19, it began the fall TV season as an independent under new WNPA call letters. The UPN affiliation moved to channel 19 in January. Viacom's Paramount Stations Group bought the station in November 1998 for $39 million, a significant return on Venture's original investment in 1994. It became a sister station to KDKA-TV after the company merged with CBS in 2000. Viacom consolidated WNPA's operations into KDKA-AM-TV's studios at One Gateway Center by 2001. WNPA began to identify on air as "UPN Pittsburgh" in late 2003 due to the fact that various cable providers in the area carry the station on different channels. As WPCW (2006–present) On January 24, 2006, Time Warner and CBS Corporation announced that The WB
