Step by Step is an American television sitcom created by William Bickley and Michael Warren that ran on ABC as part of its TGIF Friday night lineup from September 20, 1991, to August 15, 1997, then moved to CBS, where it aired from September 19, 1997, to June 26, 1998, with a total of 160 half-hour episodes spanning seven seasons. The series follows Patrick Duffy and Suzanne Somers who star as single parents Frank and Carol, respectively, each with three children, who wed and form a blended family.

TGIF was an American prime time television programming block that has aired on ABC at various points since the late 1980s. The name comes from the initials of the popular phrase "Thank God It's Friday"; however, the stars of the lineup touted the initialism meaning "Thank Goodness It's Funny." In its various incarnations, the block mainly featured situation comedies aimed at a family audience, and served as a lead-in to the long-running newsmagazine 20/20.
