If you could invite anyone to a dinner party, who would you invite? What would it look like?

That was the premise and that was the question that Richard Saul Wurman asked himself in the mid-’80s. Wurman – a U.S. architect and graphic designer – is more widely known as the person who coined the phrase "information architect." He also became a very successful publisher of travel books before acting on his impulse to invite some of the people he found fascinating to dinner. In 1990, he turned that dinner party idea into an invitation-only event called TED.

TED stands for Technology, Entertainment and Design and the annual event is open to only 1,000 people that the TED organizers deem worthy (I was very fortunate to attend TED in 2008).

The truth is that TED is much more than just technology, entertainment and design. TED is trying to change the world.

Presenters give "TED Talks" – 18-minute presentations on topics that also include science, arts, politics, culture, business, global issues and more. But, the event is not just about the presentations. It’s about what happens in the hallways during intermission and what takes place while socializing in the evening. The TED conference tagline is "ideas worth spreading" and, over the years that’s exactly what this conference has done.

In 2002, Chris Anderson (one of the people behind the magazine Business 2.0 and the very popular gaming website IGN) took over as curator of the TED conference and gave ownership of the event to his non-profit organization, The Sapling Foundation. The fee for the conference shifted to an annual membership model (around $6,000 U.S.), which includes a pass to the TED event along with club mailings and more. In the interest of spreading the ideas being shared, TED now publishes many of their TED Talks online – free.

They’re available from their website or you can subscribe for free via iTunes in Podcast format (in both audio and video). Anyone can now experience TED when and how they want.

One participant has called the event "gymnastics for the brain." On any given day, you could watch speakers as diverse as Al Gore presenting his thoughts on the environment to TV and film writer, director and producer J.J. Abrams (Lost and Alias), talk about the power of mystery. The conference is not just about growing your business, it’s about something much bigger than that. It’s about growing your mind.

For years, TEDsters (as they call themselves) converged in Monterey, Calif., but this year’s event – Feb. 3-7 – was moved to Long Beach, Calif. To expand the audience and reach, TED has announced people can watch the event live on the Internet (the cost for this is about $1,000 U.S.).

The economy has definitely made events like this even less accessible to the masses.

The first place most businesses are chopping is their event marketing and participation at conferences. If the price and travel is prohibitive, and you think the $1,000 price tag to watch it online is still a little dicey in these times, there are hundreds of past TED Talks online that are free, but here are four 18-minute ones that will melt your brain:

Sir Ken Robinson.

Creativity expert and education system re-invention evangelist Sir Ken Robinson makes a compelling, funny and brilliant presentation on the power of creativity and how we’re getting it wrong when it comes to educating our children. Essentially, we are killing creativity when we should be focusing on it.

Benjamin Zander.

Benjamin Zander is the conductor of the Boston Philharmonic. He is also one of the best speakers you will ever experience. He is the co-author of the book, The Art of Possibility, and – even if you never cared much for classical music – this will change your mind. Music and passion make people amazingly more successful and if your eyes are not shining after this presentation, it might be time to consider a different career.

Hans Rosling.

Hans Rosling proves that the devil is in the details. This amazing look at third-world myths through new data visualization will not only get you excited about the future of mankind, but might get you thinking differently about how we use data and information in business (and how boring you thought it was). Rosling is a doctor and researcher who, after speaking at TED, took on a position at Google.

Majora Carter.

You can’t have a strong business without a strong community and Majora Carter‘s emotional presentation about her fight for environmental justice in the South Bronx demonstrates the power of the human spirit and how leaders do emerge to make a difference. Watch this one with your co-workers who think that nothing can change and things have to be "the way they have always been."

The world of new business is not just about the bottom line. It’s about making the bottom line count for something. TED is a celebration of ideas and thinkers. Every day your business is poised with another challenge. Your success in navigating that challenge is going to be measured by how creative, passionate and embracing of change you are. TED celebrates that. You should join in on the celebration – either live on the Internet next week or by watching some of the past TED Talks right now.
