People have been using the www prefix for quite some time. It was originally supposed to allow companies to have multiple servers, and one (labelled via www) would serve their websites.
In reality, most companies couldn’t afford all these different servers. But for some reason, www is still being used.
Here’s a site about deprecating www. I agree with this site. Check it out: http://no-www.org/

AMEN. The http://www. thing is pointless anymore. Just kills me watching people still peck away at that double you double you double you dot.
But, in Google webmaster tools, they give you the option to choose your preference, www or no http://www.
I find it interesting, that they list the www option ABOVE the non www option.
Hmm.
