began 30 years ago as a conference about Technology, Entertainment and Design.
Conceived by architect and graphic designer Richard Wurman, it featured demonstrations of the Sony compact disc and the Apple Macintosh computer. It took six years for the next conference to be held but by the 1990s it had broadened its areas of expertise.
