WWE is World Wrestling Entertainment, (Smackdown! and Raw) which has been around for 50 years or so. TNA is a newish wrestling company where many wrestlers kicked out of WWE go to. TNA tries to compete with WWE (they're rivals) but WWE has more experience and therefore has better business then TNA.

Rey Mysterio joined WWE in 2002, so he has been in WWE for 8 years.
I don't know where you got that idea, but WWE is not going anywhere they have been in business since 1952 and still going strong!
10 years
Well WWE and WWF started in 1984 so in 2010 it's been going for 26 years. Remember, there is 1 Wrestlemaina a year and we are up to Wrestlemania 25.
