He doesn't like to reveal too many secrets to his success but Saga CEO Ed Christian did just that yesterday, most likely to let investors know the company was doing everything possible to grind out sales while the economy remains in a rut. Christian says, "If we do our craft properly, radio's 245 million listeners will respond to our advertising messages. Saga is not a flashy company. We increase business by hard work and determination. Two initiatives Christian revealed are both showing success in the city of Des Moines where Saga has 4 FM's and 2 AM's.
