Sanford and Son is an American sitcom, based on the BBC's Steptoe and Son, that ran on the NBC television network from January 14, 1972, to March 25, 1977. Known for its edgy racial humor, running gags and catch phrases, the series was adapted by Norman Lear and considered NBC's answer to Archie Bunker. Sanford and Son has long been hailed as the precursor to many other African American sitcoms. It was a ratings hit throughout its six season run. While the role of Fred G. Sanford was known for his bigotry and being cantankerous, the role of Lamont Sanford was usually a peacemaker and more conscientious. At times, both would involve themselves in schemes. Other colorful/unconventional characters were Aunt Esther, Grady Wilson, Bubba Bexley and Rollo Lawson. In 2007, Time magazine included the show on their list of the "100 Best TV Shows of All Time".
