Television is so radically different from radio.
The crew of a radio program might be three people.
Versus the crew of a television program that might have two dozen people.
On radio, no one can see what you’re wearing. On TV, you need to have heavy makeup on face and hands and any other exposed skin and it has to be touched up during the breaks. I remember one author who was being interviewed and the makeup made him choke and caused his eyes to tear up. You have to get used to the makeup.
On radio, you can more or less be your motor-mouth self. On television, every emotion shows and is transmitted … and you need intravenous caffein to maintain your “up” high-energy state.
There was one guy I knew. Didn’t watch his show much, but was flipping around and he looked “different” somehow, so I emailed him and it turned out that a family member was in the hospital. Everything shows.
It can take a lot of practice to master television broadcasting.
[It blows me away that Fr. Benedict Groeschel was able and has been able to master a live call-in television program … right after he got run over by a car. Amazing. Sometimes you can see his eyes flick to one side or another when he gets timing cues about ending a segment or closing the hour. Amazing.]
