I have taught radio and television production courses for thirty years. A lot has come and gone -- and come around again during that time. I have only had to be concerned with "obscene" materials on one occasion (in 1965). Since then, I have only had to require that any materials submitted MUST be acceptable for broadcast in a conservative small town. Students will always test the limits. The challenge is to keep the limits and stop wimping out generation after generation -- until we all have to watch nothing more enlightening than Bevis and Butthead!
