Day to Day (D2D) was a one-hour weekday American radio newsmagazine distributed by National Public Radio (NPR), and produced by NPR in collaboration with Slate. Madeleine Brand, Alex Chadwick, and Alex Cohen served as hosts. Topics regularly covered by D2D included news, entertainment, politics and the arts; contributors included familiar NPR personalities, reporters from NPR member stations, writers for Slate, and reporters from Marketplace, a show produced by American Public Media. D2D premiered on Monday, July 28, 2003, and fed to stations from noon ET with updates through 4:00 p.m. ET. It was the fastest growing program in NPR's history.
