Jimmy Wales: How a ragtag band created Wikipedia - TED Talks

Jimmy Wales went from betting on interest rates and foreign-currency fluctuations (as an option trader) to betting on the willingness of people to share their knowledge.

That's how Wikipedia, imagined in 2001, became one of the most-referenced, most-used repositories of knowledge on the planet, with more than one million articles in English (compared with the Britannica’s 80,000) and hundreds of thousands in dozens of other languages, all freely available

With a vision for a free online encyclopedia, Wales assembled legions of volunteer contributors, gave them tools for collaborating, and created the self-organizing, self-correcting, ever-expanding, multilingual encyclopedia of the future.
