TED stands for technology, entertainment, design. It started as a conference in 1984 that brought people together from these three worlds. The TED conference invites the world's best speakers to give presentations that represent some of the World's most exciting ideas. The only catch is that speakers are limited to 18 minutes for a talk!

The TED website, www.ted.com, gives you free access to over 200 of these talks (you can also subscribe through iTunes).

It may not be about Teaching English but there is plenty to inspire on this great site.
