I lived for years without TV and found out that during disasters radio had more, and more frequent, local news. The TV stations were all regional and neighbors were actually less aware of what was going on locally watching TV.
I came to the opposite conclusion myself, but it really depends on your locale. Here in the Los Angeles/Orange County area, it is usually the local TV stations who have the resources to send people out to developing situations, while the radio stations tend to rely more on information from news wires, press releases, or even listeners calling in.
We've had a lot of really bad wildfires in the last several years, and local TV news coverage has been superior to the radio news coverage in most cases IMHO, including the luxury of actually seeing wildfires from the news helicopters. Even so, I'm not sure if the people most directly affected were getting enough details even from the TV news coverage. I suppose in any fast developing situation, it's pretty rare to cover ALL the information bases to everyone's satisfaction ALL the time.
