Rickjay - A little certain-to-be-inaccurate history.
The concept was born in November 1993. The idea was a competition between varied martial arts styles to solve the age-old question, “What would happen if this style took on that style?” It was an 8-man single elimination tournament with one winner. That’s exactly what “Ultimate Fighting Championship” meant…one championship contested by everyone in the event.
In the early days, the fighters came from everywhere and employed a wealth of disciplines. Natrually, there was a pretty massive disparity between the overall ability of the fighters, especially for the first few events (UFC 1 and 2, in particular, had the most lopsided championship matches ever). Plenty of weirdness, too, and even the occasional scandal. It took all kinds…the “beer bellied bikers”, the string beans, the muscular lunks, the gritty pitbulls, and even the occasional clueless old guy.
In 4, the promoters decided to experiment with the idea of a “Superfight”, a single match separate from the tournament (that’d have its own belt), mainly because a lot of guys just didn’t have the toughness or stamina to fight three times in one day. 4’s was billed as an exhibition fight; the first actual Superfight happened in 5. This was the first break from the original meaning of UFC.
Then around…10? 14?..someone decided that three fights was just too much for anyone, and weight classes were introduced for the first time, Heavyweight and Lightweight, each of which had a 4-man mini-tournament. Another step away.
A little later, the tournament was done away with for good, and the Superfight belt became the Heavyweight belt, and UFC, for all intents and purposes, had evolved from a single event to a league, where the champions all had belts and kept them until someone beat them. Then in 2001, Zuffa bought the rights from Semaphore Entertainment Group, and the final obstacle to the event becoming fully legitimate, i.e. a self-important alphabet soup organization plastering its name on the product and sucking up a percentage of the earnings, fell.
So anyway, UFC was never an annual event. The numbering is a holdover from the old tournament days. The way it’s set up now is just like boxing, kickboxing, or a similar sport, with a card of competitors each fighting once, with one or two main events at the top, and a champion in each division. The main reason for keeping the numbering is, well, it makes each event easier to keep track of.
Oh, before I forget, there’s also something called Ultimate Fight Night, a regular event with no numerals, sort of a lower-tier event. It’s used to showcase up and comers, build up to a PPV, fill time, etc.
A little complicated, yes, but nothing unusual for a league that wasn’t supposed to make it to 1995.
