The Buffalo TV stations absolutely had extra crews out and on the road. Of course, not being in the market, you wouldn't know that. When you get 7 feet of snow, even a news crew (or backpack journalist) can't get to some stories, so viewer video gives people a glimpse of what's going on out there. There was plenty of extra coverage during the broadcast day.
Not all stations need to go wall-to-wall with coverage. The news stations should. Music stations provide a break from what sometimes becomes an on-air bludgeoning with storm information, but that doesn't mean they shouldn't offer timely, relevant, concise information on an ongoing basis. Most stations have the means. They just need the will - and a likely a few hours of overtime pay.
