I believe this is the reason for this format decision- KINK doing a 4.0 share in Portland (and of course much stronger in demo) and note it's higher than BOTH country stations in that market.
KINK has become a lot more mainstream in the last few years. They play their currents a lot more frequently than any other AAA or alternative station. As many as 40 spins a week. Their playlist is HALF the size of KPNW's. They're playing Teddy Swims, for God's sake. Plus the big factor is they have heritage. That's why they can do all that. If that was the reason they made the switch, it was an ill-informed decision.
