Anyone can "buy" time on a radio station, if he/she is willing to pay the price. That makes me so angry! These people take the good reputation of a radio station and the employees/guests that are bound by ethics -- and simply by appearing on the air, they seem to have an air of credibility. Good for you for checking farther into this! But stations often sell air time that has low value -- late night, weekends, etc. -- to make money!
