You Tube

It wasn't until I picked up a paper (remember those?) and saw an article, that I had my answer as to the 00's most important invention. You Tube. Yes, that was it. Seems like its been around longer, but it didn't start un til 2005. And we all go there now. For sports, music, Hell, anything.
So, that's my winner. You Tube as the big cultural invention of the 00's.
