It's incredibly hard to tell the price of a company, because resonably speaking the actual value of the tinyurl.com company is in the actual domain, because many scripts are available now that can copy cat what they created (or what i think they originally created) so with that the price of the domain is based on how much traffic all the domains received that have a tiny url, and the actual tnyurl website. Saying that i believe that it's worth aproximately 25,000,000 USD, just a rough guess
