Big Brother Fans Everywhere...How many different versions of BB is out there?

I live in the U.S. and I love our BB. I am all the time seeing other Countrys BB Q&A. Just wondering how many there are.
Where are you and what version do you watch?

I know the feeling I go to answer a question and its people talking about the british version or whatever, I myself watch the version with the Chen bot I've watched it since season 1. This year it is even better because with showtime you can watch big brother after dark every night from 12 am to 3 am that is the live feed their time its 9 to 12 so things can get interesting. As for how many versions of big brother there are I really don't know just know it is aggrivating to come on here and get confused like that. I hope Dick, Eric and Daniele make the final three. I hope Jen gets out this week we know she'll be nominated just hope she gets out I can't stand that whining about pictures and all that garbage any longer. Big brother is awesome!
