Concerns about contemporary forms of payola in the US prompted an investigation during which the FCC established firmly that the "loophole" was still a violation of the law. In 2007, four companies (CBS Radio, Citadel, Clear Channel, and Entercom) settled on paying $12.5 million in fines and accepting tougher restrictions for three years, although no company admitted any wrongdoing. Due to increased legal scrutiny, some larger radio companies (including industry giant Clear Channel) now refuse to have any contact with independent promoters.
