NCAA
The NCAA (National Collegiate Athletic Association) is a nonprofit organization founded in 1906 that governs college athletics across over 1,000 U.S. institutions. It sets competition rules, eligibility standards, and organizes championship events across a wide range of sports, with the NCAA Men's Basketball Tournament—March Madness—being its most high-profile and commercially significant event. Its cultural relevance traces back to the annual March Madness tournament, where the single-elimination format and bracket challenges create intense national engagement every spring. Fans return for the unpredictable upsets and buzzer-beater moments that define the tournament’s drama, making it a defining spectacle in college sports and a major source of the NCAA’s visibility and revenue.
