“The nation’s fourth-largest radio company, Entercom Communications Corp., traded airtime for gifts and payments in a payola scam that included formalized programs to sell airplay to record labels, according to a suit filed Wednesday by New York Atty. Gen. Eliot Spitzer. The suit’s most serious allegations focus on Entercom’s ‘CD Preview’ and ‘CD Challenge’ programs, in which radio executives allegedly solicited payments to improve a song’s position on national airtime charts.”
