“I Love Lucy has been called the most popular television show of all time. Such national devotion to one show can never happen again; there are too many shows on many more channels now. But in 1951-1952, our show changed the Monday-night habits of America. Between nine and nine-thirty, taxis disappeared from the streets of New York. Marshall Fields department store in Chicago hung up a sign: ‘We Love Lucy too, so from now on we will be open Thursday nights instead of Monday.’ Telephone calls across the nation dropped sharply during that half hour, as well as the water flush rate, as whole families sat glued to their seats.”
