After every Comic-Con International, I get a lot of e-mails and calls from folks who bemoan that they missed certain panels and ask — pretty please with sugar on top? — if there's a recording, either video or audio. The panels are not formally taped but are sometimes informally recorded…and one of the folks who does this is Jamie Coville. He has a whole bunch of MP3 files of panels over on this page, including the Golden/Silver Age Panel and an event I hosted called "That 70s Panel." There are also recordings there of panels I didn't host, as well as many from other conventions.
