With the flip, WWBB-101.5 became the first station in New England to go all-Christmas.
As of 3:20 P.M. Eastern Standard Time today (November 6th), WWLI-105.1 (a Soft AC station that usually goes all-Christmas every year) hasn't yet "taken the plunge", but I think they will have to at any time.
Update: 4 P.M. EST, November 6th: At 3:47 P.M. EST today, WWLI did play one Christmas song, Dean Martin's version of "Let It Snow, Let It Snow, Let It Snow!", which leads me to think that they either:
(1) Will slip-in occasional Christmas music before eventually going 24/7 all-Christmas;
(2) Had a glitch in their hard-drive system that played a Christmas song too soon and that the problem was detected and corrected, or,
(3) Did it to get us Message Board types to comment!
However, the station is streaming a 24/7 Christmas format on their website, along with the station's regular format. Once "Lite Rock 105.1" goes all-Christmas, it will be reversed: WWLI will likely have their regular AC format as an "alternate" stream on their website.
