Today, without The Sound, KLOS still has around 2.5 shares (prior to Covid).
They were closing in on a 3 share, and KLOS will become the default station for a good portion of the folks disenchanted with KROQ's new direction.
I also don't accept for a second that all the air will escape from the KLOS balloon once listening habits return to normal. I think some of the disruption to listening habits will prove to be permanent. Time will tell if my prediction comes true.
