as part of "the new TGIF" for the 1997–98 season. The two sitcoms containing such elements added to replace Family Matters and Step by Step were You Wish, a series from Boy Meets World creator/showrunner Michael Jacobs about a genie living with a family; and Teen Angel, centering on a teenager who died during an eating challenge and returns to Earth as his best friend's guardian angel. Neither show was as endearing with audiences as the TGIF shows that earned long runs in previous years, and were also disliked by critics, even with the return of Maureen McCormick (formerly Marcia Brady) and the addition of established sitcom star Jerry Van Dyke (who, unusually, had supporting roles on both new shows) to the network's Friday night lineup. The TGIF lineup began to experience sagging ratings throughout 1997–98 in part due to the audience fracture caused by its new competition from CBSs Block Party, which was enough to hurt TGIF even though the rival block itself was a failure. Even Boy Meets World and Sabrina the Teenage Witch started to experience declining ratings due to strong competition from Dateline NBC and two successful replacements to the ill-fated CBS Block Party, Kids Say the Darndest Things and Candid Camera; with the more formidable competition, after eight years, ABC was no longer the top network on Friday nights. Although You Wish and Teen Angel were designed in concept to mesh with Sabrina on the lineup, both lasted only a season (or less) before being cancelled by the network: You Wish was pulled in November, while Teen Angel lasted until February.

As part of a network-wide rebranding toward a simplified graphics package, ABC retired the traditional TGIF logo and phased out the theme song. After a moribund 1997–98 season, the 1998–99 season saw two promising shows in Two of a Kind, a starring vehicle for Mary-Kate and Ashley Olsen centering on a widowed college professor who hires one of his students to help take care of his twin daughters, and Brother's Keeper, an "Odd Couple"-style sitcom centering on a widowed college history professor who agrees to let his irresponsible pro-football
