"Says Richard Buckley, manager of Manhattan's WNEW:'1954 was the biggest year in billings and profits in our history. Sales ran 42.7% ahead of 1948, the last pre-television year.' Some local stations never had it so good. Non-network time sales rose from $276 million in 1948 to $402 million in 1954, an alltime high. The number of radio stations almost tripled from 1,004 in 1946 to 2,745 in 1955.Then, only six years ago, TV arrived. Overnight, radio lost its glamor. It also lost listeners, advertisers and talent. It began to look, and sound, half dead."
