UFC seems to be cutting into WWE's market, no matter how much Vince McMahon wants to tell himself that they are not competitors.
UFC has been rising fast in recent years, but the more popular they get, the more their flaws become noticed.
Believe it or not, wrestling used to be a legitimate, 100 percent athletic competition. Now, that was years and years and years ago, but over those years it has evolved into what is now "sports entertainment."
WWE is still, however, the biggest company in the sports fighting/entertainment realm, and UFC can learn a thing or two (there are 25 in this slideshow, actually) from WWE.
