went on the air. Hearst would purchase the remaining 50 percent of the station in 1962. WTAE-TV is the only Pittsburgh television station affiliated with a major network not to have changed ownership. Shortly before the station signed on, the FCC moved the channel 4 assignment to Pittsburgh proper following several years of petitioning by then-Pittsburgh mayor (and future Governor of Pennsylvania) David L. Lawrence. However, the FCC changed its rules so that channel 4 could have based its main studio in Pittsburgh, even if it had been licensed in McKeesport or Irwin. The station's original ownership group's connections with powerful U.S. Senator from Florida, George Smathers led to televised U.S. House hearings with both Lawrence and Smathers testifying in 1958. WTAE-TV was thus short-spaced to other channel 4 stations in Columbus, Ohio; Oak Hill, West Virginia; Buffalo, New York; and Washington, D.C.; the transmitter was located southeast of the city as a result of the move. Shortly after signing on, WTAE-TV was briefly affiliated with the NTA Film Network, sharing the affiliation with KDKA-TV, WIIC-TV (now WPXI), and WQED. WTAE-TV first adopted the "Circle 4" logo in 1973, eventually adopting the current version in 1995. Due to the design and similar callsigns, the logo has received comparisons to fellow ABC affiliate WATE-TV in Knoxville, Tennessee, who has used the "Circle 6" logo since 2011. Aside from the ABC affiliation, the two stations are not related. In 2012, the "Circle 4" logo surpassed KDKA-TV's Group W-era logo that in various forms was used from 1965 to 2003 for the longest-used station logo on Pittsburgh television. On April 24, 1980, WTAE-TV personality Nick Perry, who hosted Bowling for Dollars and also called the lottery drawings for the Pennsylvania Lottery, fixed the Lottery's daily numbers drawing so that it would come up as "6-6-6". Perry served jail time, and the drawings were moved to WHP-TV in Harrisburg a year later. This resulted in lotteries now being audited and monitored with "witnesses" from the government and/or accounting firms, and also inspired the movie Lucky Numbers. KDKA-TV aired the Lottery drawings in the Pittsburgh market after this incident until 2009, when they moved back to WTAE-TV. In April 1985, WTAE-TV became the only station in the United States to transmit the World Wrestling Federation's WrestleMania event free over-the-air, after a technical glitch prematurely ended the event's closed-circuit broadcast from the Civic Arena. In 1986,
