KFWD in 1974 or so, was a Top 40 FM station in DFW. That is, the music was Top 40, but the "presentation" was that of a "progressive" station. They would segue 3 in a row and then stop to back sell what you "just heard" and do their PSA, Liner or whatever and either play spots or start another 3 in a row.
This was during the time that KNUS 99 FM was going strong as a Top 40 with a far superior presentation that included air personalities (Ken Dowe, Kevin McCarthy, Beau Weaver, Christopher Haze to name a few), high profile promotions (Fantasy Park, High-Low, Cash Clock, Rear Window Sticker, ...), top notch news (Jack Hines and others)....
KLIF was still in the Top 40 fight as well on AM, and although they had a slight resurgence in 1975, their days were clearly numbered.
KVIL in 1974 was just under new management and coming on strong with Chapman, Gardner, Schell, Selden, Major Tom and promotions that nobody could touch...
In those days, KVIL wasn't "Adult Contemporary", that name hadn't been invented yet, but they were basically Top 40 without the heavy R&B, Rock product and teeny bopper stuff. Indeed, most of the time it was hard to tell they weren't Top 40!
.... and we know how that all worked out...
