«As for listeners, it depends on who's asking. When the National Association of Broadcasters commissioned a survey, it found general satisfaction with radio; about two-thirds of those polled liked what they heard on the air. But when the Future of Music Coalition, a Washington lobby fighting against further deregulation on broadcasting, asked similar questions, it found radio listening on the decline, especially among younger people.» (Fisher, 2007: 294)
