Going to work for the National Broadcasting Company (NBC) in 1952, Silver was with the network for 36 years, first as a radio and television sports writer, later as news writer and producer. Among the NBC sports icons with whom he was closely associated are Bill Stern, Mel Allen, RussHodges, Red Barber, Chris Schenkel, Bud Palmer, and Joe Garagiola, among many others.

During this period he wrote a sports column with cousin Jesse Silver for the Jewish Telegraphic Agency (JTA), and in 1965, the two Silvers and JTA editor Bernard Postal produced The Encyclopedia of Jews in Sports.

While still a New York University (NYU) student, where he was sports editor of NYU’s Commerce Bulletin, Silver was a sports stringer for the Associated Press and United Press wire services, as well as for the New York Times and New York Herald-Tribune.
