Frontline has entered into an “editorial partnership” with Tehran Bureau, an online news site connecting journalists, experts, readers–and sometimes anonymous contributors. The site launched today. The joint effort fits into what Frontline e.p. David Fanning refers to as “converged” journalism. The show’s senior editor Ken Dornstein tells The New York Times that means “investing in the best reporting possible, then using all platforms to incubate and publish stories.” Segments of the upcoming Frontline episode on Iran, “A Death in Tehran,” will be shown on the site before the November television broadcast.
