March Madness is an annual NCAA men's college basketball tournament held in March and April. The tournament features 68 teams from Division I of the National Collegiate Athletic Association (NCAA), who compete in a single-elimination format to determine the national champion. The tournament is known for its unpredictability and upsets, as lower-seeded teams often defeat higher-seeded teams. The tournament has become a cultural phenomenon in the United States, with millions of people filling out brackets and tuning in to watch the games. The term "March Madness" is often used to describe the excitement and intensity of the tournament, as well as the frenzy of activity surrounding it.

The March Madness tournament typically begins with "Selection Sunday," when the NCAA announces the 68 teams that have qualified for the tournament and their seedings. The teams are divided into four regions, each with 16 teams, and each team is assigned a seed from 1 to 16 based on their performance during the regular season and conference tournaments. The tournament is then divided into rounds, with each round eliminating half of the remaining teams until a champion is crowned.

The tournament is broadcast on various television networks and is widely watched by sports fans across the United States. Many workplaces and schools even organize bracket challenges, where participants fill out brackets predicting the outcomes of each game and compete against each other for bragging rights or prizes.

March Madness has also become a major event for sports betting, with millions of dollars wagered on the outcomes of the games. The unpredictability of the tournament, with lower-seeded teams frequently pulling off upsets, can make it difficult to predict the outcomes of the games.

Overall, March Madness is a highly anticipated and exciting event in the world of sports, attracting both casual and serious basketball fans alike.
