"In contrast to other Nobel Peace Prize winners in recent years, Mr. Gore is a multimillionaire who has built a media and high-tech empire around himself and his environmental work. He is an adviser to Google, sits on the board of Apple and is the chairman and co-founder of Current TV, a cable network with 38 million subscribers. He receives up to $175,000 per speaking appearance, although he waives or reduces his fee for some nonprofit companies and schools. Fast Company magazine has estimated his net worth at more than $100 million."
