some locally produced shows, such as live studio wrestling, and the children's program Sergeant Jack (which aired weekdays on the station from November 1965 to September 1976, before being relegated to weekends from that point until June 1982), hosted by former WSGN disc jockey Neal Miller, who donned a sheriff's deputy uniform for the character (which was named by Jack Caddell, founder of Homewood-based fast food chain Jack's Hamburgers, which sponsored the show); Miller would be sworn in by then-Jefferson County Sheriff Mel Bailey (with whom Caddell collaborated with in developing the Sergeant Jack character) as an honorary deputy, as a prerequisite to be allowed to wear the official Jefferson County Sheriff's uniform on-air and in promotional appearances. The program revolved around Dick Tracy and Mr. Magoo cartoon shorts, and incorporated wraparound segments in which Miller interacted with various puppet characters; typical for children's programs of its day, it also featured a studio audience made up of elementary school-aged children (by the time the program ended, the audience had been dropped, with Miller simply sitting in front of a curtain and providing introductions to the cartoons). The station also assumed the local rights to the Romper Room preschool program franchise from WAPI-TV in June 1970; the second host of the Birmingham version, former teacher Carol Aldy, remained with the program after its move to channel 42, before she was replaced that September by Rita Sparling, who hosted the show until it ended in June 1971. Mother Angelica – who, in 1981, would launch a Christian-oriented cable network based in Irondale, the Eternal Word Television Network (EWTN) – began her career by taping faith-related programs at the WBMG studios for distribution on the station and other broadcast outlets. DuBois and Southern Broadcasting tried vigorously to increase channel 42's signal coverage area and the quality of its local programming production, first by constructing a transmission tower that operated at 1.2 million watts in 1969. Next, they built a larger studio facility for the station on Golden Crest Drive, atop Red Mountain, where the studios of WBRC and WAPI were also located. However, this did not significantly improve the station's situation, likely prompting DuBois and Southern to sell WBMG to Park Communications for $5.5 million in 1973, becoming its tenth station and bringing that company to the FCC's national television station ownership limit at the time. Park significantly boosted the station's signal, erecting
