NEWTON, Mass., May 29, 2009 — TripAdvisor(R), the world's most popular and largest travel community, has won a gold Halo Award, American cause marketing's highest honor. TripAdvisor won the "Best Use of Social Media" category for their fall 2008 "More than Footprints(TM)" campaign which distributed $1 million dollars between five travel-related non-profit organizations, including: Conservation International; Doctors without Borders; National Geographic Society; Save the Children; and The Nature Conservancy. Run by the Cause Marketing Forum, Halos recognize work that advances the interests of both nonprofit partners and a business, and are judged on conceptual strength, execution, business results, and cause results. The honors were announced in a May 28 ceremony at the Cause Marketing Forum's annual conference in Chicago.
