KRTH and WROR were the ones that always amazed me. "Leave the AM alone, put an automated or live-assist AC format on the FM and we'll have a one-two sales punch." No, what you'll have is a station playing 80 percent of your playlist with fewer commercials and less talk on FM that will cannibalize your 18-49 females. I believe Bill Drake would have seen that and chosen another path.
When WNAC became WRKO in spring 1967, WRKO-FM was doing an automated Top 40 format (featuring the voice of "Arko, the shy but friendly robot" and the week's No. 1 and No. 2 hits alternating at the tops of every hour). What I'm fuzzy on these many years later -- mainly because I was only 12 when all this happened -- is when the automation stopped on FM and the "chicken rock" took over, and when the call was changed to WROR. I know WROR eventually shifted to oldies, but that wasn't until the '70s, right? So was WROR cannibalizing WRKO almost from the outset, during the Drake years?
