The Superbowl began in 1967 as the "World Championship of Football." The American Football League put its champion team against the National Football League's champion. Both leagues merged in 1970, and since then the Superbowl has been the NFL's championship game.

"Super Sunday," the day on which the Superbowl is played, has become something of a National Holiday, as people all over the country gather to watch the big game. It is, after all, the most watched event in the United States. Therefore, it has also become a venue for innovative advertising.

This year, the Seattle Seahawks play the Pittsburgh Steelers. Most sports savants predict the Steelers to win by about 4 points.

If you're watching the game, look for the larger, more aggressive Steeler defense to try and wear down the Seahawks. As for offense, the Steelers have a very solid "passing game," meaning that you can expect they will try and throw the ball.

The Seahawks, on the other hand, are a very kinetic team--you will probably see a lot of motion when they are on offense. Look for the Seahawks to try and control the ball, meaning that they will try to stay on the offense; the Seahawks' defense is likely to be overwhelmed if they spend too much time on the field.
