The Arbitron ratings released in 1984 showed an increase in listeners to Stern's show. Having moved shifts to 3–7 pm, he attracted audience shares of 3.8%, 4.2%, and 4.6% that year. The show was popular among males aged between 18 and 34, a highly-marketable demographic for advertisers. Stern acquired a 5.7% share in 1985, the highest rating at the station in four years, pushing the station's ranking in afternoons from eleventh to first place in three years. Among the success, tension between management and Stern grew further. On September 30, 1985, the show was cancelled due to what management termed as "conceptual differences" between themselves and Stern regarding his show. "Over the course of time, we made a very conscious effort to make Stern aware that certain elements of the program should be changed", said program director John Hayes, whom Stern had nicknamed "The Incubus." "I don't think it's appropriate to say what those specifics were." In 1992, Stern believed that Thornton Bradshaw, at the time chairman of RCA which then owned WNBC, was driving in his limousine having heard his "Bestiality Dial-a-Date" segment and ordered his firing.
