The first D23 Expo took place at the Anaheim Convention Center from September 10–13, 2009. It was the single largest gathering of all things Disney ever assembled. Almost every part of The Walt Disney Company was represented. The "D" stands for Disney, and "23" represents 1923, the year that Walt Disney arrived in California and founded what was to ultimately become The Walt Disney Company. My Saturday appearance was great. Meeting all these really serious Disney fans was a pleasure.
