The Internet has undoubtedly transformed the way we support great causes. For years, non-profits and individuals alike have flocked to social media to spread awareness, bolstering viral philanthropy through crowdfunding sites such as Indiegogo, Fundly, GoFundMe and others.

A handful of campaigns stand out in recent memory: Funding a vacation that turned into retirement for bullied bus monitor Karen Huff Klein; the collaboration between Humans of New York and Tumblr for Hurricane Sandy relief; and, most recently, support for the victims of the Boston Marathon bombing across various platforms.

The positive effects of these individual campaigns were readily apparent at the conclusion of their funding periods, but by juxtaposing the numbers now, we can see the real impact of viral philanthropy as a movement.
