TEDTalks

TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader.

The annual conference now brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).

Our mission: Spreading ideas.

We believe passionately in the power of ideas to change attitudes, lives and ultimately, the world. So we're building here a clearinghouse that offers free knowledge and inspiration from the world's most inspired thinkers, and also a community of curious souls to engage with ideas and each other. This site, launched April 2007, is an ever-evolving work in progress, and you're an important part of it. Have an idea? We want to hear from you.

The TED Conference, held annually in Long Beach, is still the heart of TED. More than a thousand people now attend -- indeed, the event sells out a year in advance -- and the content has expanded to include science, business, the arts and the global issues facing our world. Over four days, 50 speakers each take an 18-minute slot, and there are many shorter pieces of content, including music, performance and comedy. There are no breakout groups. Everyone shares the same experience. It shouldn't work, but it does. It works because all of knowledge is connected. Every so often it makes sense to emerge from the trenches we dig for a living, and ascend to a 30,000-foot view, where we see, to our astonishment, an intricately interconnected whole.

In recent years, TED has spawned some important extensions.

TEDGlobal is a sister conference held every other year, and in a different country on each occasion. The first conference was held in Oxford, England, in 2005; the second, in June 2007, was held in Arusha, Tanzania. The themes of the global conference are slightly more focused on development issues, but the basic TED format is maintained.

The TED Prize is designed to leverage the TED Community's exceptional array of talent and resources. It is awarded annually to three exceptional individuals who each receive $100,000 and, much more important, the granting of "One Wish to Change the World." After several months of preparation, they unveil their wish at an award ceremony held during the TED Conference. These wishes have led to collaborative initiatives with far-reaching impact.

TEDTalks began as a simple attempt to share what happens at TED with the world. Under the moniker "ideas worth spreading," talks were released online. They rapidly attracted a global audience in the millions. Indeed, the reaction was so enthusiastic that the entire TED website has been reengineered around TEDTalks, with the goal of giving everyone on-demand access to the world's most inspiring voices.

Today, TED is therefore best thought of as a global community. It's a community welcoming people from every discipline and culture who have just two things in common: they seek a deeper understanding of the world, and they hope to turn that understanding into a better future for us all.
