First it was a presence in Second Life, now it is brand channels on YouTube...
Paris Hilton has launched a brand channel on YouTube... YouTube gets to cover some of its extreme bandwidth costs (which some say are up $1m or more...) and the detrius get concentrated. Although the implementation is a little hard to see - search Hilton and your get a list of videos...
Focusing through the lens of a brand could make navigating the site easier and concentrate viewing - but will that destroy the anarchy that currently prevails, propelling pointless but amusing crap to the front page? Maybe not but the imperative to make money had to come sometime.
