Family Matters is an American sitcom revolving around the Winslow family, a middle-class African-American family living in Chicago; the series ran for nine seasons (eight on ABC and one on CBS). The series is a spin-off of Perfect Strangers. Midway through the first season, the show introduced the Winslows' nerdy neighbor Steve Urkel (played by Jaleel White), who quickly became its breakout character and eventually a main character. The series had a total of 12 main characters, with some characters portrayed by multiple actors.
JoMarie Payton originally appeared on Perfect Strangers in 1987 in the recurring role of Harriette Winslow, the elevator operator for the Chicago Chronicle. Reginald VelJohnson later made one appearance on Perfect Strangers in the 1988 episode "Crimebusters" as Carl Winslow, policeman and husband of Harriette Winslow. Due to large popularity of Payton's character with audiences, the character was spun off to its own show, Family Matters. While Payton, VelJohnson, and Telma Hopkins (as Harriette's widowed sister Rachel) were initially the stars of the show, with the focus being around the Winslow family, Jaleel White was introduced as nerdy neighbor Steve Urkel during the middle of the first season in the episode "Laura's First Date"; Urkel, the lovesick pursuer of Laura Winslow (portrayed by Kellie Shanygne Williams), quickly became a popular breakout character with audiences.
Shortly after the introduction of White as Steve Urkel, Shawn Harrison was cast in the role of Waldo Faldo, initially as sidekick to a bully portrayed by Larenz Tate that terrorized everyone and Urkel. When Tate and Harrison were offered the chance to return to the show on a recurring basis, only Harrison took up the offer. As a result, his character was re-written to be the best friend of Eddie Winslow (portrayed by Darius McCrary). Harrison eventually joined the main cast in the 1992–1993 season. Soon after, Michelle Thomas was cast in the role of Myra Monkhouse, love interest and later girlfriend of Steve Urkel. Initially cast on a recurring basis, Thomas joined the main cast as a regular in the 1994–1995 season. In the 1996–1997 season, Orlando Brown was added to the cast as Jerry Jamal "3J" Jameson, a troubled youth being mentored by Steve who becomes the foster child of the Winslows.
