Comic-Con 2017 is taking place at the San Diego Convention Center through the weekend. Over the years, the number of people who attend Comic-Con each year has gone up from a few hundred a few decades ago, to some 130,000 people this year. NPR Morning Edition co-host David Greene talked with NPR's resident Comic-Con expert, Arts Editor Nina Gregory, who's at the event.
