All four "TGIF" shows featured as part of the block's 1990–91 schedule were produced by Miller-Boyett, with "Perfect Strangers", "Family Matters" and "Full House" being joined by the short-lived "Going Places". Being a more adult-targeted entry in the 9:30/8:30 "TGIF" slot, "Going Places" initially lagged behind its sister shows; a mid-season retool, one that placed an equal emphasis on underage characters, improved ratings (although "Perfect Strangers" maintained a similar, virtually exclusive focus on adult characters even after moving to "TGIF"). "Going Places" was cancelled after one season in spite of its ratings increase, and was replaced in the 1991–92 season by "Baby Talk", a sitcom based on the film "Look Who's Talking". "Baby Talk" initially scored high ratings as a mid-season replacement on "TGIF" in the spring of 1991 (trying out in the "Going Places" time slot). In its second season, however, ratings collapsed. Also joining the lineup for the 1991–92 season was another Miller-Boyett series, the "Brady Bunch"-inspired "Step by Step" (a vehicle for Suzanne Somers and Patrick Duffy, whose cast also included former "Going Places" co-stars Staci Keanan and Christopher Castile), which went on to become a "TGIF" mainstay for the next six seasons. (The pickup of "Step by Step" as well as the renewal of "Baby Talk" resulted in "Full House" concurrently being moved off the "TGIF" lineup to lead ABC's Tuesday comedy block, alongside hit series "Roseanne" and "Coach" and freshman hit "Home Improvement".)
