text: what is ufc???and oin which channel does it come???   ultimate fighting championship started in the early 90's with fighters like ken shamrock and royce (pronounced hoyce) gracie. it's a mixed martial arts full contact fighting event that up until 2 years ago could only be seen on pay-per-view. you can watch the reality show "the ultimate fighter" on spike tv.  if you've never seen it, it's well worth watching. it's addicting. especially now, when boxing is soooo bad.
