Samsung donated $1 to charity per re-tweet of Ellen's Oscars Selfie

"While we were a sponsor of the Oscars and had an integration with ABC, we were delighted to see Ellen organically incorporate the device into the selfie moment that had everyone talking. A great surprise for everyone, she captured something that nobody expected. In honor of this epic moment and of course, the incredible response of nearly 3 million re tweets, we wanted to make a donation to Ellen’s charities of choice: St Jude’s and the Humane Society. Samsung will donate 1.5 million dollars to each charity."
