The UFC has consistently advocated for more comprehensive MMA regulation, adopting the unified MMA rules in November 2000. These rules help ensure athlete safety and fair competition by providing a unified set of rules for the sport – something that was lacking in the early days of mixed martial arts. All UFC fights will now be governed in full compliance with the provisions of the unified MMA rules. The UFC continues to support sports commissions as they work to update and improve the unified MMA rules. If a foul is sanctioned, the arbitrator may, at his or her discretion, deduct one or more points as a penalty. If a foul puts a fighter out of action, the game can end with a disqualification if the foul was intentional, or a non-fight if it was unintentional. If a foul prevents a fighter from continuing later in the fight, it ends with a victory by technical decision for the injured fighter if the injured fighter is ahead on points, otherwise it is a technical draw.  During this first part of the organization, the UFC featured a host of different styles and fighters. In addition to the aforementioned Royce Gracie, Ken Shamrock and Patrick Smith, the competitions also included Hall of Famer Dan Severn, Marco Ruas, Gary Goodridge, Don Frye, Kimo Leopoldo, Oleg Taktarov and Tank Abbott.
Although the first events were dominated by jiu-jitsu, other fighting styles were successful: first wrestling, then floor and pound, kickboxing, boxing and dirty boxing, which eventually merged into modern mixed martial arts. Although the UFC used the slogan «There are no rules» in the early 1990s, the UFC actually operated with limited rules. It prohibited bites and eye piercings and allowed techniques such as hair pulling, headbutts, groin blows and hooks. [ref. needed] While games usually ended with submission, knockout, or missing teeth, in recent years the trend has seen a slight majority of games last until the final seconds. Researchers believe this is the result of UFC athlete improvements and greater standardization of training and technique, but the result is that fans are getting a better show than ever before. Whether it`s a pay-per-view match or a UFC Fight Night broadcast on ESPN+, if your partner asks you, «How long is a UFC fight?» tell them the truth: let`s just hope for a little longer. As for the upcoming pay-per-view, UFC 249 on April 18, UFC president Dana White said the event will likely continue, but in a new location behind closed doors. It was originally scheduled to take place at Barclays Center, but the New York state government issued a stay-at-home order.   On March 18, the New York State Athletic Commission also withdrew its sanction for the event.  Due to international travel restrictions and other withdrawals, a revised map for UFC 249 was revealed on April 6, with a location yet to be determined.
  The next day, White announced that he had booked an unspecified venue for two months to host both UFC 249 and other future events with U.S. fighters. He also revealed plans to secure a private island, known as Fight Island, to host events with international fighters. After a dramatic last-minute fifth-round victory by UFC middleweight champion Anderson Silva over Chael Sonnen at UFC 117, Lesnar finally handed his belt to Cain Velasquez undefeated by TKO in the 1st round at UFC 121. The fight led to Velasquez`s eighth technical knockout in his first nine MMA fights.  It wasn`t until 1999, at UFC 21, that today`s five-minute rounds were first introduced. The preliminary round matches consisted of two; Main tickets and non-championship headliners, three; and championship fights, five. These adoptions officially lowered the maximum duration of a UFC fight to a maximum of 10 minutes and a maximum of 25 minutes. By the way, if a match «goes over the distance» or time has to pass without knockout or submission, boxing`s adopted «10 must» system was introduced to ensure that there is always a winner – no matter how controversial it is. A standard UFC fight consists of three five-minute rounds. However, the title fights will be extended to five five-minute rounds.
WOW Promotions and SEG produced the first event, later called UFC 1, at the McNichols Sports Arena in Denver, Colorado, on November 12, 1993. Art Davie acted as booker and matchmaker for the show.  The show suggested finding an answer to sports fans` questions such as: «Can a wrestler beat a boxer?»  As with most martial arts at the time, fighters usually had skills in a single discipline and little experience against opponents with different abilities.  The TV show featured kickboxers Patrick Smith and Kevin Rosier, savate fighter Gerard Gordeau, karate expert Zane Frazier, shooter Ken Shamrock, sumo wrestler Teila Tuli, boxer Art Jimmerson and 175 lb (79 kg) Brazilian jiu-jitsu black belt Royce Gracie – the younger brother of UFC co-founder Rorion, whom Rorion chose to represent his family in the competition. Gracie`s submission skills proved to be the most effective in the inaugural tournament, earning him his first UFC tournament championship. after submitting Jimmerson, Shamrock and Gordeau one after the other. The show was extremely successful with 86,592 pay-per-view TV subscribers. Originally, it was planned that the two organizations would operate separately, but at the same time as card promotion plans with the champions and main contenders of the two organizations together. However, after purchasing Pride, Dana White felt that the Pride model was not sustainable and that the organization would likely collapse with many Pride veterans such as Antônio Rodrigo «Minotauro» Nogueira, Maurício «Shogun» Rua, Dan Henderson, Mirko «Cro Cop» Filipović, Wanderlei Silva and others already realigned under the UFC brand.  On October 4, 2007, Pride Worldwide closed its Japanese office and laid off 20 employees who had worked there since the closure of its parent company, Dream Stage Entertainment (DSE).  The promotion`s first televised event – UFC on Fox: Velasquez vs.
dos Santos – broke its form by showing viewers only one fight. In the main event, Junior dos Santos abruptly dethroned UFC heavyweight champion Cain Velasquez by knockout at 1:04 in the first round. The TV show peaked with 8.8 million viewers watching the fight with an average audience of 5.7 million, making it by far the most-watched MMA event of all time and the most-watched martial arts event since the HBO fight between Lennox Lewis and Vitali Klitschko in 2003.  Fights that take place on The Ultimate Fighter are classified as demonstration fights under NSAC sanctions and therefore do not count towards a fighter`s professional record. The results of the game also do not need to be immediately made public, so the results of the fight remain unknown to the public until the episode`s broadcast date.
