Television/Radio Age magazine was a US television industry trade magazine published by "Television Editorial Corporation" from 1953 to 1989.
 Originally titled "Television Age", the magazine began as a monthly until 1956 and biweekly thereafter.

 The smallest publication in the series was Number 1, with 10 pages, and the largest was Number 43, with 156 pages.
