These stations are successful as is...
The ratings demonstrate the cost reductions have no impact
Please look at the ratings for WBZ and WRKO again. WBZ is the most listened to radio station in Boston, ages 6 and up. WRKO is number 8.
Keep in mind these are not normal times with a pandemic and coming off a contested election.
Both have served WRKO and WBZ well.
These might not be "normal ratings" either.
