non-currents were no more than 5 years old and the station played about 70 of them in total. In his book Rockin' America, Sklar said he was sensitive to payola concerns and advanced airplay. Through the years, WABC was known by various slogans, "Channel 77 WABC" and later "Musicradio 77 WABC". Due to the high number of commercials each hour, WABC played no more than two songs in a row and there was frequent DJ talk and personality between every song. The station averaged 6 commercial breaks per hour but they were no more than 3 ads in a row. Often the air personalities delivered live commercials in their own humorous style, so that listeners would consider the spot part of the entertainment. In addition, between songs, disc jockeys were required to provide so-called program matter. Program matter could include a time check, a weather report or simply some disc jockey banter, which enabled the disc jockeys to inject their personalities and humor into their shows. Early 1960s disc jockeys included Dan Ingram, Herb Oscar Anderson, Charlie Greer, Scott Muni, Chuck Dunaway, Jack Carney, Bruce "Cousin Brucie" Morrow and Bob "Bobaloo" Lewis.

Noted sportscaster Howard Cosell did a brief weekday evening sportscast on WABC, as well as hosting a late Sunday night interview show called "Speaking of Everything." Especially in the afternoons and evenings, WABC was the station that teenagers could be heard listening to on transistor radios all over the New York metropolitan area. Due to its strong signal, the station could be heard easily over 100 miles away, including the Catskill and Pocono Mountains, and through much of Connecticut and Rhode Island. After sunset, when AM radio waves travel farther, WABC's signal could be picked up around much of the Eastern U.S. and Canada. Bruce Morrow often spoke about how he
