When a TV station signed on in the 40's and 50's, the usual convention was that the network on the radio side was adopted by the television.
There were a few exceptions such as WDEF/Chattanooga (NBC radio but CBS on TV). It was the same story when WTIC-TV/Hartford went from being an indy to CBS, with the radio retaining its longtime NBC affiliation. Off the top of my head, WJBK-TV/Detroit signed on as a CBS primary but the radio side was Mutual (with CBS over on WJR).
I'm sure there are many others fitting this pattern. What are those that you can recall?
