Most people still think Hotels.com, Vrbo, Travelocity, Hotwire.com, Orbitz, Ebookers, CheapTickets, CarRentals.com, Wotif, and Trivago are separate companies, yet they are just Expedia brands and sell Expedia inventory. For the most part, all of them exist only as marketing brands and use the Expedia backend. I used to work for one of those brands and when we were all laid off during the transition, we were not allowed to tell our customers the brand was becoming Expedia.
