On March 6, 1967, WLTV became affiliated with ABC and since then has aired all of its shows, with the exception of season one of "NYPD Blue", which was instead broadcast on Fox affiliate WKNT (previously WQQB, now dual NBC/CBS affiliate WNKY). After affiliating with ABC, the station moved to new studios located on Morgantown Road in downtown Bowling Green. After spending some time off the air in late 1969 due to an explosion destroying its transmitter, Argus Broadcasting sold the station to Professional Telecasting Systems on June 11, 1970. The explosion was due to an estimated 48 sticks of dynamite being placed at the bottom of the tower. It is suspected that a local bootlegger at the time did not appreciate the news spotlighting his operation. This did not collapse the tower but it stood with a bow in it; the transmission line on the lower section of the tower was destroyed and the tower was unsafe. A temporary tower with a temporary antenna was erected at the site and the station continued operation with diminished coverage a few months later. This heralded the relocation of the transmitter to the site where it now operates (and shares with PBS member station WKYU-TV).
