TEDx is a project launched by TED in 2009 to encourage TED fans everywhere to organize TED-style activities. As of April 2010, more than 500 TEDx events have been held in cities and villages around the world. The cost of on-site participation is usually much lower than that of TED conferences. Some people also point out that the quality of such TEDx conferences is uneven because they are not under unified management.

The role of TEDx:

This localized, self-organized event TEDx can bring people together to share experiences similar to TED experience. At TEDx events, videos of talks and live speakers combine to inspire deeper discussions and closer connections within the group.

The development history of TED:

In 2001, media tycoon Chris Anderson bought TED. He called himself the "Guardian of TED" and changed the field of TED speakers from The original three fields of technology, entertainment, and design have expanded to all walks of life, inviting scientists, philosophers, artists, explorers, psychologists, linguists, religious leaders, philanthropists, etc. to join in, committed to making TED a A global brand that transcends conferences.

At the first TED conference in 1984, someone brought CDs that would become popular all over the world, and the first Apple computer was also brought to the podium. Today, the new version of Macbook Air has made countless fans around the world crazy about it.

While changing the world, TED itself has also grown from a "dinner party" with less than a thousand members to a community of 500,000 people watching its videos every day 26 years later (to 2010). Since 1990, the participating elites have gathered in Long Beach, California, USA every March to enjoy this "Super Brain SPA".
