I prefer television as well. I need to be able to see and hear what the person is saying. If a famous person or a politician is being interviewed or is giving a speech, I will pay attention to their mannerisms, facial expressions, as well as their tone of voice. I feel more connected (or disconnected) to them this way.
I prefer the medium of talk radio. I only listen to it in the car, but I find it much more engaging than music as I drive. I find it fascinating to hear perspectives from all kinds of people all over the country as they call in and express themselves on a wide variety of subject matter. I try to listen to programming from more than one perspective, as well. I hear interesting things that make me think about and question my own beliefs as well as the beliefs of others.
interviews such as those that Barbara Walter conducted with famous people certainly seemed rather candidly revealing as well as insightful because of Ms. Walter's ability to probe politely and sensitively. Likewise, recountings of people's lives on the Biography station seems objective as there are several testimonials by family members, friends, etc.
Special in-depth reports that cover several days' broadcasting are usually well-developed and documented, as well, so that a certain objectivity is attained, lending the stories credible for the audience.
