Forty years ago, an American designer and two of his friends hosted a TED talk – the first in a series of lectures about technology, education and design at a conference center in California.
Beginning in 1990 it became an annual event, and now it’s spreading through a collection of independent programs focused on local and regional people and issues.
This year, TEDx hosted its first event at a Virginia prison. Sandy Hausman has details.
