Baseball's Biggest Prize

Does anyone know what the World Series Trophy (pictured to the left) is actually called? I'm one of the biggest baseball fans you will meet, and I didn't even know....so of course, I looked into it today.

It is called the Commissioner's Trophy. Kind of a lame name, I know. Did you also know that, unlike the Stanley Cup, they actually build a new Commissioner's Trophy each year for the team that wins the World Series to keep? Apparently they do the same thing with the Lombardi Trophy for the Super Bowl Champions. Where's the history in that??
