The Mexico City-based company owns 15 radio stations, including 11 in Mexico City, and now operates Emmis-owned KXOS-FM (93.9) in Los Angeles under a long-term LMA. Its total-year 2008 broadcasting revenue grew from 655 million pesos in 2007 to 735 million in 2008, or $53.1 million in U.S. dollars. In addition, Radio Centro also showed overall gains in broadcast income and net income for 2008. The secret to their success? They’re selling a lot of radio ads, as evidenced by the higher sales commissions paid in 2008. Grupo Radio Centro’s SEC filing can be viewed here.
