I honestly started watching mma with ufc 2 but it wasn't live obviously. I stopped following mma by ufc 10 or so (they stopped showing ufc events where i lived at that time ).
When I came to the states i got hooked again with the first season of tuf. I still remembered Royce, Tank, Ken, Oleg, Ruas, Keith Hackney, Severn. But I didnt know a thing about Couture, Liddell, Vitor, Tito, Hughes, etc. I just had to catch up and learn about what went down while i wasnt following mma during those 8-10 years. Then i learned about the existence of Pride, Shooto, Pancrase, etc.
