It seems like a hundred years ago.
Overnight, it became dead simple to copy and post video to the Internet and everyone started doing it.
Copyright owners wailed and gnashed their teeth. Can you blame them? Suddenly, it was easier to copy and repost their uber-expensive products than it was to make paper copies. (At least you have to pay to make photocopies.)
To get the ball rolling, Viacom filed a $1 billion lawsuit against Google and YouTube. (That lawsuit is still pending I believe.)
In the meantime, someone got intelligent.
