WonderCon

WonderCon is an annual comic book, science fiction, and film convention held in the San Francisco Bay Area (1987–2011), then—under the name WonderCon Anaheim—in Anaheim, California (2012–2015, 2017–present), and WonderCon Los Angeles in 2016. The convention returned to the Anaheim Convention Center in 2017 after a one-year stint in Los Angeles due to construction at the Anaheim Convention Center.
The convention was conceived by retailer John Barrett (a founder of the retail chain Comics and Comix) and originally held in the Oakland Convention Center. In 2003, it moved to San Francisco's Moscone Center. The show's original name was the Wonderful World of Comics Convention.
