One of the most popular in professional sports today is mixed martial arts. Practitioners of mix one martial art discipline with another, never focusing on one. Except for rules for the health and safety of the fighters, like no kicking of the head when on the ground, rules are such that almost anything goes inside the ring. Knees, elbows, palms, can be utilized for striking together with almost any form of grabbing, grappling and wrestling. This is the reason why fighters and practitioners need to know at least two disciplines; one for stand-up combat and another for grappling. For example, the UFC fighter Lyoto Machida has a fighting style which is a blend of Shotokan Karate, Brazilian Jiu-jitsu and sumo wrestling. Mixed martial arts main production is the Ultimate Fighting Championship or UFC. In the beginning, UFC matches could be watched live. With pay-per-view TV, ultimate fighting videos could now be viewed at home. Still, pay-per-view could only get the UFC so far. They had to increase the number who can watch and view ultimate fighting videos.
With increased internet bandwidth, the availability of streaming video websites would aid the UFC in allowing more people to watch ultimate fighting videos. Websites like www.sherdog.com regularly made recent and past UFC matches available for download as ultimate fighting videos. The UFC also released ultimate fighting videos compiled in a single DVD. Finally, members of video-sharing websites like www.youtube.com regularly made available for viewing all kinds of ultimate fighting videos, even going so far as uploading recent UFC matches captured live.
