I kept hearing this guy's 'Focus on the Family' audio tapes being played in local (small) shopping complexes during the day..

"He is an evangelical Christian with conservative views on theology and politics. He was recently named "The Most Influential Evangelical Leader in America" by Christianity Today magazine, and many see him as the successor to evangelical leaders Billy Graham, Jerry Falwell and Pat Robertson.

The question is, are there a group of evangelical cristians selling these audio tapes to local supermarkets?

Is it right for supermarkets to broadcast evangelical messages?
