I know some people do it really early. Everyone I know said wait until 3. I tried with my first around 21 months and all he would do is sit for 3 seconds and get up, run off naked and pee on the floor. EVERY TIME! So I quit and potty trained him in about a week when he was almost 3. I tried around 2 years old with my daughter and she basically did the same thing. I tried again about 3 months before she turned 3 and she potty trained in 1 day. I thought she was going to be impossible to potty train, because I would try to get her to pee on the potty sometimes and she would never do it, not even once by accident. Then I bought her some Elmo underwear and she was trained just like that. It was weird. So anyway, I waited and it worked for me to wait, but some people have success training really early.
