The San Diego Comic-Con (SDCC) is the largest Comic-Con in the world. It’s a four and a half day event, Thursday through Sunday with a Preview Night on Wednesday.
It began as a small comic book minicon in March 1970, lasting just one day. The success of that event let them have a three-day convention in August of the same year. The convention was held in hotels and other locations for the first two decades. It moved to the San Diego Convention Center in 1991.
It attracts fans of a variety of entertainment types and genres. (It has about 130,000 attendees per day.) There are a range of panels covering many facets of popular arts, seminars, workshops, awards, autograph signings, and a cosplay masquerade contest.
