Channel One, the controversial advertising-funded TV network that reaches 7 million secondary schools, faces declining revenue and its owner, Primedia, is looking to sell. The station has been especially hit by marketing pullbacks on food and beverage ads aimed at children, the subject of increasing criticism by prominent members of Congress and, most recently, the American Academy of Pediatrics. The home page of ChannelOne.com has featured U.S. Army "All American Bowl" football ads, as well as Pepsi products.
