Why football counts as America's national sport, what the NFL is, where the game came from in the early university leagues, and what the Super Bowl means.
American football is impossible to follow without a short explanation and obvious once you have one. The video gives the explanation: why the sport occupies the place it does in the United States, what the NFL is and how big it is, and where the game came from - the early university leagues that shaped its rules.
Then the game itself, which is more strategic and more physical than students expect, and the Super Bowl, which is less a final than a national event. For an ESL class it is a culture lesson with a lot of concrete vocabulary attached, and for anyone who has wondered what is happening on the screen it answers the question in under two and a half minutes.
