Louis "Lou" Grant is a fictional character played by Edward Asner in two television series produced by MTM Enterprises for CBS. The first was The Mary Tyler Moore Show (1970–1977), a half-hour light-hearted situation comedy in which the character was the news director at fictional television station WJM-TV. A spinoff series, entitled Lou Grant (1977–1982), was an hour-long serious dramatic series which frequently engaged in social commentary, featuring the character as city editor of the fictional Los Angeles Tribune. Although spin-offs are common on American television, Lou Grant remains the only character to have a leading role on both a popular comedy and a popular dramatic series.
