Backed by heavyweights in three disparate industries--Amazon, CAA, and Greylock Partners--WhoSay.com lets celebrities do something Twitter and Facebook don't: own their online content. Tom Hanks, Anderson Cooper, Lindsay Lohan, Paul Feig, and nearly 900 other stars have already signed up for the service.
Paying celebrities to pimp your product is nothing new. From Gillette courting ZZ Top front men to shave (they declined), to Weight Watchers convincing Sarah Ferguson to endorse their slim-down system (she did), marketing gurus have long used star power to shine some light on their own products.
The newest target: CNN anchor Anderson Cooper and his gray hair.
