Fascinating indeed!
Fascinating how the counterfactual sometimes ends up paralleling reality - if you posit, as Chas does, that "KB-FM" would have evolved into today's Kiss, well...they ended up as sister stations pretty quickly anyway, didn't they?
It's quite true that few top-40 AMs successfully migrated to FM. The small roster includes not only WHOT and WPRO but also WJET in Erie and KDWB in Minneapolis. It's remarkable how many stations that had an FM in house and could have made the move easily never did so. How different would things have been in Rochester if LIN had shifted "95BBF" to "92BBF" in 1981-82 and cut WPXY off at the pass?
(Two more answers for chas: yes, 92.9 in Pittsburgh was KDKA-FM originally; and yes, WHEN's FM sister didn't come along until much later. I believe it wasn't until 1980 or so that Roy Park bought the former classical WONO-FM 107.9, which went through phases as country WRRB, beautiful music WRHP and country WHEN-FM before arriving at top-40 as WWHT.)
