Reality television has generally got a bad rap, but Emily Nussbaum—who received a Pulitzer Prize, in 2016, for her work as The New Yorker’s TV critic—sees that the genre has its own history and craft. Nussbaum’s new book “Cue the Sun!” is a history of reality TV, and roughly half the book covers the era before “Survivor,” which is often considered the starting point of the genre. She picks three formative examples from the Before Time to discuss with David Remnick: “Candid Camera,” “An American Family,” and “Cops.” She’s not trying to get you to like reality TV, but rather, she says, “I'm trying to get you to understand it.”
