A college student in Wisconsin listens to a disc jockey in Jamaica play the latest rapso (calypso rap) music. A children�s advocacy group unites its geographically diverse members via private broadcast. A radio listener hears an ad for a computer printer and places an order immediately using the same medium on which he heard the ad.
