Dr. Stanley Liebowitz of University of Texas at Dallas. Talks about his two studies of whether radio play helps music sales. Neither found evidence that sales are increased by radio play but evidence that sales have been harmed by radio. Explains this means total sales and not sales of individual artists (who obviously benefit from radio play). Time spent listening to radio is time not spent listening to purchased sound recordings. In the absence of radio, a person can listen to nothing or pre-recorded music.
