The 9th Emmy Awards, later referred to as the 9th Primetime Emmy Awards, were held on March 16, 1957, to honor the best in television of the year. The ceremony was held at the NBC Studios in Burbank, California. Desi Arnaz hosted the event. All nominations are listed, with winners in bold and series' networks are in parentheses. Categories were sorted based on running time, instead of by genre. The top shows of the night were Caesar's Hour and Playhouse 90. Each show won a then-record five major awards, (however, two of Playhouse 90's wins came in now defunct categories). Caesar's Hour became the first show to be nominated in all four major acting categories. Caesar's Hour also made history when it swept the four acting categories. For over fifty years, it remained the only show to win every major acting award. In 2004, the miniseries Angels in America became the second show, and first miniseries/television film, to sweep the acting field. In 2020, Schitt’s Creek became the first comedy or drama series to win in all four acting categories.
