"Who Done It?" was, at the time, the highest-rated television episode in U.S. history. It had a Nielsen rating of 53.3 and a 76% share, and it was estimated that 83 million people watched the episode, more than the number of voters in that year's presidential election. The previous record for a TV episode had been the 1967 finale for "The Fugitive". "Who Done It?" now sits second on the list, beaten in 1983 by the final episode of "M*A*S*H". In 2011, Ken Tucker of "Entertainment Weekly" named "A House Divided" number one of the seven most "Unforgettable Cliff-Hangers" of prime time dramatic television.
