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 and had abandoned plans to add child actress Alisan Porter to its cast as a young neighbor to lead characters Balki and Larry after one episode that same season). 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.) During the most successful years of TGIF, the main characters of one of the Friday prime-time sitcoms would "host" the two-hour block of episodes for that week. Always in character, they would introduce each show and comment on the proceedings afterward. Sometimes, characters from a series that did not air on the Friday schedule would appear to host. For example, in January 1996, Daniel Hugh Kelly, Betsy Brantley and other stars from the short-lived drama Second Noah served as one-time-only guest hosts of TGIF as a cross promotion for the new Saturday series. Occasionally, the hosts for the evening would find a common thread between each show. During the fall seasons in the late 1980s and early 1990s, casts from various TGIF shows would host Saturday morning preview specials, which outlined much of new programs set to air on the Saturday morning fall schedule (after The Walt Disney Company began programming the network's
