#2 Perez Hilton

Perez Hilton is a blogger and television personality known for posts covering gossip items about celebrities. He is also known for posting tabloid photographs over which he has added his own captions or "doodles."  He originally registered the site as, "PageSixSixSix.com," in 2004. But it didn't take long for the New York Post's Page Six gossip channel to sue him for trademark infringement and unfair competition. His site was already a leading blogs site when he switched to "PerezHilton.com," a play on socialite Paris Hilton. PageSixSixSix.com now redirects to the New York Post.

#1 Overstock

Overstock.com, also known by its shortcut, O.co, is an American online retailer company founded by Patrick M. Byrne in May 1999. Overstock has seen its share of flip-flopping throughout the years. The site got rebranded to "O.co" to simplify and shorten its name. Customer confusion on the .co domain prompted a retraction, and the company has now reverted back to the original. However, O.co still redirects to the site.
