NEW YORK — The ice bucket challenge's phenomenal success is making other charitable organizations rethink how they connect with a younger generation of potential donors. Since the ALS Association began tracking the campaign's progress on July 29, it has raised more than $53.3 million from 1.1 million new donors in what is one of the most viral philanthropic social media campaigns in history. Thousands of people, including celebrities like Taylor Swift and Oprah Winfrey, have posted videos of themselves getting buckets of ice water dumped over their heads and challenging others to do the same — or donate money to The ALS Association, which raises money for Lou Gehrig's disease research and assistance.
