For several months now, 92.3 (and 98.7 AMP Radio in Detroit) have dropped Commercial-Free Mondays and replaced it with Commercial-free hours all day, everyday. I listen a lot to NOW and they do a LOT of these hours everyday. They promote them very often with music teasers of 'coming up in the next commercial-free hour' and the jocks always mention them. I think it's a much better move than commercial-free one day of the week.
