Thanksgiving. Black Friday. Small Biz Saturday. (Day of rest.) Cyber Monday. Then, on Tuesday, Dec. 2, it’s #GivingTuesday, the largest day of microphilanthropy in the world—and a platform for doing-good collaborations like no other. This year, 10 comms agencies are working together to promote the day and its founding partners, the United Nations Foundation and 92nd Street Y, and countless other publicists and agencies are working hard on behalf of their clients who have signed on. And sign on they have: More than 19,000 partners have aligned to make a difference locally and globally on a day that lets people support a cause or two they feel passionately about (perhaps forgoing a daily latte or even a new pair of Theory pants to contribute). CrowdRise has been simulating the building of a Giving Tower, which at press time was nearly the height of the Eiffel Tower. Havas PR North America has clients from Samahope and the Center for Great Expectations to Ruby Rocket’s, JCPenney and Fox Restaurant Concepts benefiting from the day or being benefactors. Dec. 2 is a day that won’t be forgotten for a long time to come in many ways.
