Making good on its promise, WCVB aired more local programming than any other television station in the nation throughout the 1970s and 1980s. One of its local programs, "Good Day!", which first premiered in 1973 as "Good Morning!", broke ground by taking its entire production on the road and broadcasting from locations outside of the Boston area and around the world. "Good Day!", along with "The Morning Exchange" on Cleveland's WEWS-TV, served as a prototype for the format of ABC's "Good Morning America". "Good Day!" lasted until 1991.
