The Ultimate Fighting Championship, or UFC, is a big sports company. 
The first UFC event was in 1993. 
Today, the sport has many strict rules. Fighters use gloves to stay safe. They also use weight classes to keep fights fair. This mix of many skills is called mixed martial arts. The fighters compete in a special eight-sided ring. This ring is called the Octagon.

The UFC began in the early 1990s. 

In the early days, the rules were very simple. There were no weight classes for the fighters. This meant a small fighter might face a much larger opponent. One famous fighter was Royce Gracie. He used Brazilian jiu-jitsu to win the first tournament. He defeated fighters like Ken Shamrock and Gerard Gordeau.
Today, the UFC is a very large and successful enterprise. Dana White has been the president since 2001. He became the CEO in 2023. The company has expanded to Australia, Asia, and Europe. It has held over 750 events around the world. In 2023, the UFC merged with the WWE. This created the new company called TKO Group Holdings.
The Ultimate Fighting Championship, commonly known as the UFC, is the world's largest mixed martial arts (MMA) promotion company. 
To understand how the UFC functions, one must look at the Octagon. The Octagon is a trademarked, eight-sided fighting arena surrounded by a chain-link fence. 
Competition in the UFC has evolved through several distinct stages. In the early 1990s, the events were essentially no-holds-barred tournaments. These contests lacked weight classes and had very few rules. This allowed fighters of vastly different sizes to face one another. Later, the organization transitioned to a system of specialized weight divisions. This change ensured that opponents were more evenly matched in size. Another major shift was the move from tournament-style brackets to the "Superfight" format. The Superfight was a non-tournament match used to determine a reigning champion. Eventually, the Superfight model phased out the older tournament structures entirely.
The history of the UFC began with an ambitious idea to find the most effective martial art. Businessman Art Davie proposed an eight-man single-elimination tournament called "War of the Worlds." He worked with martial artist Rorion Gracie and film director John Milius. They were inspired by "Gracies in Action" videos from Brazil. These videos showed Brazilian jiu-jitsu students defeating experts in karate, kung fu, and kickboxing. The first official event, UFC 1, took place on November 12, 1993. It was held at the McNichols Sports Arena in Denver, Colorado. 
During these early years, the UFC faced significant challenges and controversy. In 1996, U.S. Senator John McCain campaigned to ban the sport. He famously described the matches as "human cockfighting" after seeing tapes of the events. This led to thirty-six states enacting laws to ban no-holds-barred fighting. New York even banned the sport just before UFC 12 occurred. To survive, the UFC had to reform its entire approach. The company began cooperating with state athletic commissions to implement stricter rules. They introduced time limits, authorized referees, and judges to decide draws. These reforms helped the UFC move from a controversial spectacle toward a regulated sport.
The economic significance of the UFC has grown exponentially over the decades. In 2015, the company earned US$609 million in revenue. Its domestic media rights agreement with ESPN was valued at $1.5 billion over five years. In 2016, the parent company Zuffa was sold to a group led by Endeavor for US$4.025 billion. Endeavor later bought out the remaining owners of Zuffa for $1.7 billion in 2021. Most recently, the UFC signed a massive seven-year deal with Paramount Skydance Corporation. This deal is valued at US$7.7 billion and begins in 2026. This agreement will cause the UFC to exit the pay-per-view business model entirely.
Today, the UFC is part of a larger corporate structure following a major merger. In September 2023, the UFC merged with the wrestling promotion WWE. This merger formed the new public company known as TKO Group Holdings.
