Expedia's transaction-oriented websites, such as Expedia.com and Hotels.com, attract only about one-third of Expedia Inc.'s advertising and media revenue, the company stated. TripAdvisor, the hotel review network, is Expedia's media star, attracting the other two-thirds. Expedia Inc. is investing heavily in its TripAdvisor business and sees a lot of upside, particularly internationally.
"We see a ton of potential still in the European markets, especially on the Continental markets, where we see more shift going into [cost-per-click-type] advertising," Khosrowshahi said. "TripAdvisor is a very big gateway to more and more travelers on a worldwide basis," he added, alluding to TripAdvisor's presence in the U.S., the U.K., Ireland, France, Germany, Italy and Spain.
