Haven't heard of YouTube yet? It's a user-generated melange of crappy and cool home videos and random content grabbed from TV and video games from all over the world (don't get us started on the copyright issues right now). More than anything, it's a glimpse into the future.
Closer to today, it was interesting to see Apple (presumably) use it as a platform to show off their new MacBook. It supposedly has been viewed more than 35,000 times.
How did YouTube get so successful? One big boost came from the video that swept the nation in December. You don't know it? What?! It was crazy delicious. So delicious that YouTube blasted past Google Video in popularity.
