Michael A. Wiener

Michael A. Wiener (c. 1938 – August 2, 2009) was an American business executive who was one of the two founders of the Infinity Broadcasting Corporation in 1972, ran the company as president and chairman, and became a philanthropist after selling the business and its 44 radio stations to Westinghouse Corporation in 1996 for $3.7 billion.

Born in Brooklyn, Wiener got his start in the radio business selling radio advertising. He started calling rock and roll "American music" as a ploy after prospective buyers were reluctant to place ads on stations that played the genre, which they "associated with the drug culture and the peace movement". He had been selling ad space for Metromedia when he joined together with Gerald Carrus to purchase San Francisco-area radio station KOME in 1972, a station that played free-form rock, with his investment covered with money raised from his wife and associates, along with $5,000 he had obtained after selling his father's stamp collection.

As the company grew, both Wiener and Carrus left their day jobs to work full-time at Infinity. Wiener was the company's president starting in 1972 and shifted to chairman in 1979, a position he retained until selling the company. In 1981, they hired Mel Karmazin as president of the radio division, by which time Infinity owned three stations. Over the next decade, Karmazin led Infinity on a buying spree and brought in shock jock Howard Stern, moving the business into successively larger radio markets.
