Ever wonder how much money our favorite little plumber has made for Nintendo? Well, wonder no more, as Nintendo has disclosed the exact amount (give or take a decimal) of units the Mario series has sold since it's inception in 1983. For kicks, I've included the top five franchises for Nintendo, with units sold as of March 2007:

Total Mario series: more than 198 million units sold worldwide
Total Pokémon series: more than 164 million units worldwide
Total Zelda series: more than 52 million units worldwide
Total Donkey Kong series: more than 48 million units worldwide
Total Metroid series: more than 13 million units worldwide

I wish the Metroid series was higher up. That series has a lot of potential, and it just has never seem to hit mainstream like Nintendo's other franchises.
