I honestly don't think someone can reach that amount, say in a year alone with adsense. If we're talking about companies, yes there are some that earn more than that in a year through adsense. Weblogs Inc. is one of them.
Interesting thing about Weblogs Inc. Their CEO is Jason McCabe Calacanis. Somebody bought domain www.jason-calacanis.com and spammed the internet on his behalf and made fun out of him. I guess, it's possible to make $1,000,000.00 - all you need is rich content and high quality traffic (lots of it).
