It’s time to pick your brackets for March Madness! Since 1939, this annual basketball tournament has featured the best men’s college teams from around the country. Also known as the NCAA Division I Championships, it’s become one of the most popular sporting events in the United States. In 2021, an estimated 36.7 million Americans filled out brackets to predict the winners of each game.
This year, 68 teams will participate in the competition. Each team is placed in one of four geographic regions and is eliminated when it loses a game. The winners of each region will advance to the tournament semifinals, known as the Final Four, in April.
