I was looking at the early returns on ratings for the Christmas season and it's a safe bet to believe that two months of all-Christmas will be with us for years to come. The question now will be who'll flip by Labor Day.
At some point, going all-Christmas would have to be a long-term bad thing for the station, right? Flip in October or September and you risk a large portion of your regular listenership finding a new favorite AC station (or even listening more to classic hits or country) and not returning when the seasonal schmaltz is stowed away.
