TripAdvisor launched its "More than Footprints" philanthropic campaign, intended to enlist customers to vote for a travel-related charity most worthy of a $1 million donation. The effort, which runs through November 9, encourages visitors to TripAdvisor's Web site to vote for one of five travel-related nonprofits - Conservation International, Doctors Without Borders, National Geographic Society, The Nature Conservancy, and Save the Children - to determine what percentage of a $1 million donation the groups will receive from the organization. Each nonprofit will receive a traction of the donation, to be announced November 12, based on what portion of the vote they receive, but all groups will be awarded at least $50,000.
