Anyone who watched UFC on regular terms - can he tell us when there are matches and such?
Nowadays, they have close to 20 events per year(if you include pay-per-views and UFC Fight Nights).
The UFC now is completely different to what it was when it first started. Basically Rorion Gracie brought Vale Tudo to the US, aiming to show what would work in an actual fight(and that Gracie Jiu Jitsu > rest). So the first UFCs were tournaments running over the course of one night, pitting martial art vs martial art(there were no well rounded fighters back then, or mixed martial artists as they would call them now).
His brother Royce(who wasn't even the family's best fighter, that was Rickson) dominated competition in the early UFCs by using what would now be considered as basic brazilian jiu-jitsu skills, as pretty much nobody had any idea what to do once the fight hit the floor. After that the popularity of BJJ exploded.
If you watch any of the early UFCs from 90s you will see that it was basically the Wild Wild West; bare-knuckled, sumo wrestlers fighting people half their size, a guy with ONE boxing glove, flying teeth, no rounds & time limits, etc.
