SPEAKER 1: The glory and the violence of football was beamed into tens of millions of American living rooms during primetime.

SPEAKER 2: Here come the hits, the bangs, the blocks, and the fights, cause all my rowdy friends drop in on Monday night.

SPEAKER 3: People like the violence of it. You watch pro football game. And naturally, the biggest cheers are for the touchdowns. But the second biggest cheers are for a nasty hit.

STEVE YOUNG: I describe it as the moment of impact, the moment when you actually have to go tackle somebody. It's really a game of will.

LEIGH STEINBERG; The actual logo of Monday Night Football showed helmets hitting together. And it became part of the popular jargon. He knocked him silly. Knocked him to the moon.

PLAYER: Set the tone. Knock him out. Knock him out. Let's go.

SPEAKER 6: There's no question the NFL marketed that violence. That's what we love about the game.
