I was asked in an interview why we call ourselves Colonial Radio Theatre, and not the Colonial Audio Theatre.
To me, Radio Theatre is a classic term. It is instantly identifiable. "But it sounds old" Well, in 15 years we have not had a problem selling them - and I get MANY letters and emails from grade school, middle school, High School kids saying how they enjoy this 'n that (and Dibble gets even more fan mail); so that's not really a worry. If they like the show, they will listen. If they don't like the show, they wont listen, not matter what you call it.
Radio Theatre has a classic sound to it. Audio Theatre sounds like something you buy at Wal Mart for your DVD set-up. So, we call ourselves Radio Theatre. It's not dead, it's not old, it's alive and kicking and not stuck in the 40's or 50's. Bottom line, it's not about what you call yourself - it's about keeping the listener listening.
