Jennifer Keishin Armstrong grew up in the southwest suburbs of Chicago, where she spent most of her time putting on shows in her parents’ garage, studying TV Guide, devouring Sweet Valley High books, lip-synching to Debbie Gibson, and memorizing every note of every George Michael song. This finally came in handy when she got a job at Entertainment Weekly, where she worked for a decade. Her work has since appeared in many places, including BBC Culture, The New York Times Book Review, Vice, New York magazine, and Billboard. She’s the author of the New York Times bestseller Seinfeldia: How the Show About Nothing Changed Everything; a history of The Mary Tyler Moore Show, Mary and Lou and Rhoda and Ted; and Sex and the City and Us: How Four Single Women Changed the Way We Think, Live, and Love. She now lives in Manhattan.
