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 Saturday morning lineup in 1997, following its prior acquisition of ABC, these preview specials were hosted for the remainer of "TGIF"s run by the hosts of "Disney's One Saturday Morning").
