For anyone interested in how digital technology is changing storytelling — and every other creative endeavor — last Thursday's "Remix" discussion between Lawrence Lessig and Shepard Fairey at the New York Public Library was beyond fascinating. The evening was occasioned by the legal row about Fairey's iconic "Hope" poster, which he based on a three-year-old photograph of Barack Obama taken by an AP photographer in Washington. With the Associated Press threatening legal action for alleged copyright violation, Fairey filed suit earlier this month seeking a ruling on the issue. At the NYPL event, sponsored by Wired, he joined Lessig for a discussion moderated by Steven Johnson, author of the newly published Joseph Priestley biography The Invention of Air. What could have been a run-of-the-mill complaint about copyright abuse turned instead into a lively give-and-take on the dual modes of pop culture that are slugging it out today: passivity v. participation. Or put another way, old media v. deep media.
