My parents and one remaining grandparent have cable TV—mostly news channels—on about 16 hours a day in their house. TV's always on in whichever room one of them's in. The one of them who gets out of the house more than a single-digit count of hours a week spends most of the time driving, which means AM radio (ahem) that entire time.
