San Diego Comic-Con

• 1. Introduction

  ›

  San Diego Comic-Con began on a single day in March 1970, when a handful of comics fans gathered in San Diego hoping to prove something could grow from nothing. Shel Dorf, a Detroit-born enthusiast who had already run one of the first commercial comics-fan conventions in the mid-1960s, organized that gathering as what he called a "dry run" for the larger event he hoped to stage. Sixty to seventy-five people showed up. Five months later, in the basement of the U.S. Grant Hotel, the real thing drew 300. What started in a hotel basement became, by Forbes' account, the largest convention of its kind in the world.

  What questions does that rise leave open? How did a gathering of a few hundred science fiction readers become a 130,000-person annual event that shapes how Hollywood markets its biggest films? What does it mean for an entertainment convention to outgrow its own home city? And what happens when an institution built on fandom collides with trademark law, a global pandemic, and a historic labor strike all within the same decade? The rest of this story tries to answer those questions.

• 2. A Basement and a Dream

  ›

  The August 1-3, 1970 convention drew Ray Bradbury, Jack Kirby, and Forrest J Ackerman to that U.S. Grant Hotel basement, secured by one of the founding group, Ron Graf. That founding group was notably large: twelve people are credited, including Richard Alf, Ken Krueger, Mike Towry, Barry Alfonso, Bob Sourk, Scott Shaw, John Pound, Roger Freedman, David Clark, and Greg Bear, alongside Dorf himself.

  Krueger's Alert Books shop in Ocean Beach served as the informal meeting ground where the early conventions took shape. Krueger also handled early business matters and pushed for the event to be structured as a non-profit organization, a decision that would define the convention's identity for decades. Alf co-chaired the first multi-day convention with Krueger, then became chairman in 1971.

  By 1975, the convention had incorporated as a nonprofit. Alf later identified one key to early growth: deliberately networking with other fan communities, naming the Society for Creative Anachronism and the Mythopoeic Society as groups that brought both talent and organizational strength to the committee. By the late 1970s, the show had grown large enough that a visiting publisher's representative walked the floor, stunned, privately noting to himself just how much bigger it was than other conventions of the time.

  The first few years moved through multiple venues, including the El Cortez Hotel and the University of California, San Diego, before the convention finally settled into the San Diego Convention Center in 1991. The official name changed to Comic-Con International: San Diego in 1995, and the convention's distinctive logo was designed that same year by Richard Bruning and Josh Beatman.

• 3. Scale and Economics

  ›

  Since 2010, Comic-Con has filled the San Diego Convention Center to capacity with over 130,000 attendees every year. Publishers Weekly has called it the largest show in North America. It is also the largest convention of any kind held in the city of San Diego itself.

  The estimated annual regional economic impact has been placed above $140 million, though that figure has not gone unchallenged. In 2009, critics argued the estimate overstated the impact by not accounting for negative effects on seasonal businesses, low individual spending by attendees, and the fact that many attendees already live in San Diego. The figures themselves have shifted year to year: the 2009 convention was estimated at $180 million, the 2014 convention at $177.8 million, and the 2016 convention at $150 million. The 2023 convention, held during a major labor strike that kept many studios away, still generated an estimated $161.1 million economic impact with approximately 135,000 attendees.

  By 2018, competition from conventions in New York City and Washington, D.C. had intensified enough that San Diego Comic-Con was described as competing for both attendees and companies' time and budgets. Even so, Publishers Weekly that year called it a must-attend event.

  The convention operates on a lean structure: a panel of 13 board members, 16 to 20 full-time and part-time workers, and about 80 volunteers working through committees. Proceeds fund the convention itself, as well as two affiliated organizations: SAM: Storytelling Across Media, and WonderCon. In 2015, the organization used a limited liability company to purchase three buildings in Barrio Logan. In 2018, it purchased a 29,000 square foot office in San Diego's Little Italy neighborhood.

• 4. Hall H and the Hollywood Pivot

  ›

  The 2004 convention marked a turning point. That year the event expanded into Hall H of the San Diego Convention Center, occupying the entire exhibit space, and the films presented included Batman Begins, The Incredibles, and Sin City. A new relationship between Comic-Con and the film industry was forming.

  By the 2011 convention, at least 80 television shows were represented on the floor and in panel rooms, compared to about 35 films. Premium cable networks like HBO and Showtime used the convention to promote series including Game of Thrones and Dexter. Streaming services including Netflix and Amazon Prime Video built increasing presences from the late 2010s onward.

  The convention center's geography became part of the drama. Hall H seats just over 6,100 people and Ballroom 20 seats approximately 4,900. At least 17 separate rooms in the convention center are used for panels and screenings. The neighboring Hilton Bayfront's main ballroom adds another 2,600 seats, and the Marriott Marquis serves as the anime headquarters and hosts nighttime film screenings.

  In 2013, there were 1,075 total panels, with anime-focused panels making up the largest single category at 29 percent, followed by comics-focused panels at 26 percent. That same year, the convention hosted 1,036 vendors. The offsite footprint has also expanded dramatically; in 2018, it was estimated that nearly 200,000 people would be in downtown San Diego specifically because of Comic-Con related exhibits and events, well beyond the convention center's official capacity.

• 5. Sellouts, Scalpers, and the Space Problem

  ›

  In 2006, Comic-Con closed Saturday registration for a few hours to manage overcrowding. It was the first time that had happened. For 2007, the convention introduced a three-day membership that excluded Saturday as a pressure valve, but that show went on to sell out Saturday anyway, along with Friday and Sunday for the first time. Both the four-day and three-day memberships also sold out for the first time in 2007.

  For 2008, the convention abandoned on-site registration entirely, selling memberships only in advance. All memberships sold out before the convention opened for the first time. That sellout gave rise to secondary market speculation, with Comic-Con memberships appearing on eBay and Craigslist at inflated prices. An attendance cap has been in place since 2007.

  In April 2008, David Glanzer, Comic-Con's director of marketing and public relations, acknowledged the organization had been approached by other cities but said he did not think anyone wanted to leave San Diego, describing it as a perfect fit despite the expense. By October 2009, Preview Night for the 2010 show had already sold out. By November 2009, all 4-day passes for 2010 were gone. On the 26th of July 2010, 4-day passes with Preview Night access for the 2011 convention sold out two hours before the 2010 convention even closed.

  A proposed $520 million expansion of the San Diego Convention Center received approval from the California Coastal Commission in October 2013. The plan would have added approximately 225,000 square feet of exhibit space, an additional 35 percent, plus an 80,000 square foot ballroom 20 percent larger than Hall H, and 500 new hotel rooms adjacent to the center. The expansion stalled in 2014 due to a lawsuit and was effectively frozen by 2015 after financing fell through. Comic-Con nonetheless extended its San Diego contract, first to 2021, then to 2024.

• 6. Pandemic, Strikes, and Disruption

  ›

  On the 17th of April 2020, the 53rd convention was cancelled due to the COVID-19 pandemic and two stay-at-home orders issued by California Governor Gavin Newsom. A digital streaming replacement called SDCC@Home was held during the original dates. On the 1st of March 2021, organizers announced a second cancellation, judging it premature to hold a full-scale in-person event. A smaller in-person event called San Diego Comic-Con Special Edition was held in November 2021, requiring proof of full COVID-19 vaccination or a recent negative test and mandatory face masks.

  The full-scale convention returned in July 2022, again with vaccination proof or negative test requirements and mandatory masks. That year was the first in-person convention since 2019, and attendees who had held over badges from the cancelled 2020 show through the cancelled 2021 show were finally able to use them.

  On the 13th of July 2023, SAG-AFTRA approved a strike against the Alliance of Motion Picture and Television Producers, creating the first concurrent actors' and writers' strike since 1960. Disney, including Marvel and Lucasfilm, Netflix, Sony Pictures, and Universal Pictures all pulled out of Comic-Con ahead of the event. Hall H sat empty on the convention's final Sunday. The cast of Philippine television series Voltes V: Legacy attended the 2023 event, becoming the first Philippine television program to attend Comic-Con.

  In July 2024, San Diego Police Chief Scott Wahl cited Comic-Con as an exigent circumstance to fast-track installation of smart streetlights and automated license plate readers in the area. A lawsuit filed in December 2024 alleged the surveillance systems were deployed improperly, without disclosing their locations or the nature of the claimed emergency circumstances.

• 7. The Trademark Wars

  ›

  In 2014, San Diego Comic-Con sent a cease and desist order to the organizers of Salt Lake Comic Con, asserting that "Comic-Con" and "Comic-Con International" were registered trademarks and that any use of the term "comic con" implied an unauthorized association with the San Diego event. A U.S. court ruled in San Diego's favor and awarded $20,000 in damages, though it did not find the infringement willful.

  The ruling had ripple effects. Phoenix Comiccon changed its name to Phoenix Comic Fest as a precautionary response. In 2017, Salt Lake Comic Con changed its name to FanX Salt Lake Comic Convention. On the 16th of January 2018, Salt Lake Comic Con filed a motion for a new trial.

  The disputes pointed to a tension at the center of the event's identity. A convention that began as a scrappy gathering of fans had acquired enough institutional weight to litigate over two ordinary English words. The convention's own corporate name, San Diego Comic Convention, does business as Comic-Con International, a brand valuable enough to protect in federal court, and expansive enough that other regional conventions now navigate around it when choosing their names.

• 8. Lore, Legacy, and the Museum

  ›

  By 2017, the organization had acquired a lease on the Federal Building in Balboa Park, originally built for the California Pacific International Exposition and previously occupied by the San Diego Hall of Champions, with plans to open a Comic-Con Museum. Hiring for the museum began by October 2017. During the 2018 convention, organizers cited the need for additional funds as the reason the museum had not yet opened, and set a fundraising target of $25 million with a hoped-for opening date of late 2020 or 2022.

  The convention's cultural reach has been documented in other forms. In 2020, SiriusXM and Stitcher produced Comic-Con Begins: Origin Stories of the San Diego Comic-Con and the Rise of Modern Fandom, a six-part podcast hosted by Brinke Stevens of Slumber Party Massacre, featuring interviews with more than 50 original contributors alongside figures including Neil Gaiman, Kevin Smith, and Felicia Day. That podcast was expanded into the book See You at San Diego: An Oral History of Comic-Con, Fandom, and the Triumph of Geek Culture, written by Mathew Klickstein and published by Fantagraphics on the 6th of September 2022. The book includes forewords by cartoonists Stan Sakai and Jeff Smith and an afterword by Wu-Tang Clan's RZA.

  On the 28th of March 2024, Academy Award and Emmy Award-nominated executive producer David Permut and producer Oscar Boyson announced they would create a feature-length documentary about Comic-Con, drawing on both the book and the podcast series. The Eisner Awards, which Comic-Con hosts and which recognize creative achievement in American comic books, carry a reputation in the comics industry comparable to the Academy Awards in film. Announced in 1985, Rick Geary's toucan design was adopted as the convention's official logo that same year, and it remains the face of the institution that grew from a 300-person basement gathering to a global cultural calendar fixture.
