The Search and Give is a program that donates money to charities when users use Live Search through a special web page:

By signing up at www.searchandgive.com, consumers can start donating one-cent to more than 100K schools and 900K non-profit organizations worldwide, every time they use the Internet to find whatever interests them – up to 500 searches permitted per person per month. People can also convert the tickets they’ve earned playing games on Microsoft’s Live Search Club, at www.club.live.com, into donations for those same schools or charities!
