...1. The World Series 2. The Super Bowl 3. The FIFA Cup 4. The Kentucky Derby The Super Bowl is the championship game of the National Football League (NFL) in the USA. It is a face-off between the American Conference and the National Conference within the League. The first Super Bowl took place on January 15, 1967. The game has grown into quite a cultural phenomenon since then, with many households holding huge viewing parties. By the early 21st century it had become a day of eating in the USA surpassed only by Thanksgiving Day. Some families also watch (or watch instead) the Puppy Bowl on the cable channel Animal Planet. Puppies play in a model stadium, and the program has a special Kitty Half-Time Show. All animals are from shelters and adoption information is provided on the air.
