Given the economic problems we now have, and as retailers could have a disastrous Christmas shopping season (and for most commercial radio stations that play music, most of their revenues come from retail advertisers), could 24/7 Christmas music begin on or around November 1st on most stations that usually do so?
Many retail advertisers love putting spots on all-Christmas radio stations, so I think it wouldn't be far-fetched for retail advertisers and their agencies to pressure broadcasters by telling them "We could struggle this Christmas season. Remember that retailers like us give your industry most of it's revenue. You can help us with Holiday sales if you start 24/7 Christmas music early, say on November 1st, as it will remind people to open their wallets and start their Christmas shopping".
