On May 31 in 1999...77 WABC-AM, New York, presented "WABC Rewound" where the news/talk station broadcast airchecks from its glory days when it was a Top 40 formatted music Radio station.
At first, WABC's early days in the 60s as a Top 40 station were humble ones.
Top 40 1010 WINS was the No. 1 hit music station and WMCA, which did a similar rock leaning top 40 format, was also a formidable competitor, while WABC barely ranked in the Top Ten. Fortunately for WABC, the other Top 40 outlets could not be heard as well in more distant New York and New Jersey suburbs, since WINS, WMGM, and WMCA were all directional stations.
WABC, with its 50,000-watt non-directional signal, had the advantage of being heard in places west, south, and northwest of New York City – a huge chunk of the growing suburban population – and this is where the station began to draw ratings.
Early in 1962, WMGM, owned by Loew's, which then owned MGM, was sold to Storer Broadcasting. Upon its sale, WMGM reverted to its original WHN call letters and switched to a middle of the road music format playing mostly non-rock artists such as Frank Sinatra, Nat King Cole and Andy Williams.
Sam Holman was the first WABC program director of this era. Under Holman, WABC achieved No. 1 ratings during much of 1962, after WMGM reverted to WHN. By the summer of 1963, WMCA led the pack among contemporary stations, with WABC at No. 2 and WINS slipping to third place. It has been said, but is difficult to verify, that WMCA dominated in the city proper, while WABC owned the suburbs. This would be consistent with WMCA's 5,000-watt directional signal.
GM Hal Neal hired Rick Sklar as WABC's program director. He would go on to become a member of the Radio Hall of Fame and be credited as one of the pioneering architects of the Top 40 format.
Under Sklar, the station went to the shortest playlist of any contemporary music station in history. The number one song was heard about every hour during the day and every 75 minutes or so at night. The other top 5 songs were heard nearly as often. Other current songs averaged once to twice per airshift. The station played about 9 current hits per hour and several non-current songs. The non-currents were no more than 5 years old and the station played about 70 of them in total.
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.
