Yes, indeed, television. The Stadium Club has TV, there is a nine-inch monitor between every two seats in the press box, and the Circle Suites are studded with color TV (one has six)—all connected to the network telecast that is otherwise blacked out in the Dallas-Fort Worth area when the Cowboys are playing at home. Some Circle Suite sets are placed against rear walls so customers playing bridge with their backs to the field can still see the game.
Or, suppose, so Bob Hayes can catch a touchdown pass and rush back to watch himself on instant replay over the heads of people who are watching him watch himself. That is involvement that makes change for more than a dollar.
