Facebook "likes" organ donors
Last year Arizona organ donors saved more than 477 lives with their donations. And now Facebook wants to help. From the KJZZ newsroom, Weston Phippen reports.
Facebook CEO Mark Zuckerberg says U.S. and U.K. users will be able to enroll as organ donors via links on the world's biggest social networking site. Facebook users who are already organ donors can add that information to their Facebook Timelines.
Zuckerberg says his friendship with Apple Inc. co-founder Steve Jobs, who had received a liver transplant before he died last year, helped spur the idea. There are more than 100 million registered donors in the U.S.; there are 1.8 million donors in Arizona.
