Multichannel (Less Than $10 Million): African Wildlife Foundation

That this was a matching-gift campaign supported by White’s own donations — “When folks at the African Wildlife Foundation told me about the threats to rhinos and other beloved creatures … you can be sure I wasn’t going to just lie down and mourn the loss. I decided to do something … and to do it with you. I decided to double the impact of the gift you make today by matching it one-to-one with my own gift.” — makes it even smarter.
