In 2005, Negroponte spoke at the World Economic Forum, in Davos. In this talk he urged industry to solve the problem, to enable a $100 laptop, which would enable constructionist learning, would revolutionize education, and would bring the world's knowledge to all children. He brought a mock-up and was described as prowling the halls and corridors of Davos to whip up support. Despite the reported skepticism of Bill Gates and others, Negroponte left Davos with committed interest from AMD, News Corp, and with strong indications of support from many other firms.
