From 1982, here is a commercial for WIVK-AM/FM. At the time, WIVK-AM and FM broadcasted a country music format and includes a jingle about WIVK entitled "There's Only One".
This commercial aired during a music special entitled "Around The World in '82" which featured performances from the 1982 World's Fair.
I did not have recording equipment with me so I pointed the camera to the television. A better clip will be uploaded once I get some recording equipment in the near future.
