Vary Senior Entertainment WriterWhen the COVID-19 pandemic caused the cancellation of the 2020 San Diego Comic-Con, it was the first time in the 50-year history of the fan convention that it would not take place.“It was really a heartbreaking decision,” says David Glanzer, chief communications officer and strategy officer at Comic-Con Intl., the organization that oversees SDCC and its sister event WonderCon in Anaheim, Calif., which also had to be canceled.
