WonderCon was started in 1987 in Oakland, California, as “The Wonderful World of Comics Convention.” The show was the brainchild of Bay Area comics retailer John Barrett, who called on a number of friends and associates to help realize his vision, including Bob Borden, Bryan Uhlenbrock, Rory Root, and Mike Friedrich. With the third year, “WonderCon” became the official name of the convention. The original show included all the classic comics convention features: an Exhibit Hall with dealers selling old and new comics and other items, programming, anime screenings, and games. Comic-Con International took over the show in 2002 and moved it from Oakland to downtown San Francisco in 2003. After 15 years as a Bay Area event, WonderCon was forced to move to Anaheim in 2012, due to construction at its San Francisco home, the Moscone Center. Since 2012, the event—now called Comic-Con International Presents WonderCon Anaheim—has been held in southern California, at the Anaheim Convention Center. While it is still the hope to one day return the show to its San Francisco and Bay Area roots.
