YouTube looks like it is finding a way to generate revenue from their large user base:
Beginning Tuesday, YouTube will roll out its first Brand Channel, where Warner Bros. Records will promote Paris Hilton's debut album, "Paris."
Brand Channels are much like the channels created for all YouTube users who upload their homemade videos to the site, though the purpose of a Brand Channel is to sell a product rather than to simply promote one's ability to attract an audience for their work.
YouTube will help drive traffic to the Brand Channels it sells, and the channels might have sponsors, as is the case with the Paris Hilton Channel, sponsored by Fox's "Prison Break." (Quote from Washington Post)
Marshall Kirkpatrick from TechCrunch weighs in to say:
YouTube reportedly pays more than $1 million each month in bandwidth costs and some people have been concerned that it would be a challenge to turn its huge traffic into money. Thus Paris Hilton to the rescue. (Quote from TechCrunch)
Overall, I think that this is an unobtrusive way to generate revenue without jeopardizing the user experience. With any luck, YouTube can make enough money off of this effort (and similar efforts) to pay for the increasing bandwidth costs that come with being a popular video site.
