Karen survived as a stand-alone series, but all ties to 90 Bristol Court vanished from Karen — including the handyman character Cliff Murdock — after the January 4, 1965, episode. Karen lasted the rest of the 1964-65 television season, but did not long outlive 90 Bristol Court. NBC canceled Karen in February 1965. Its last new episode aired on April 19, 1965, and its last primetime rerun on August 30, 1965.McNeil, Alex, Total Television: The Comprehensive Guide to Programming From 1948 to the Present, Fourth Edition, New York: Penguin Books, 1996, , p. 445.Brooks, Tim, and Earle Marsh, The Complete Directory to Prime-Time Network and Cable TV Shows, 1946–present (Sixth Edition), New York: Ballantine Books, 1995, , p. 546.
