When many of us were growing up, we had three network TV channels to choose from and an occasional independent station or two. It didn't take long to figure out what few programming options you could watch on any given evening.
What a difference from today, when countless channels are offered on cable or by satellite. The all news channels, such as CNN or Fox News, fill much of their programming with interview segments involving public officials, experts or hired analysts. Even local TV stations are expanding their news shows, often with interview segments using local experts.
