Due to the mega-hit success of "Sabrina the Teenage Witch", ABC thought they'd surround it and "Boy Meets World" with other supernatural-themed shows for "the new TGIF". The two more sitcoms to replace "Family Matters" and "Step by Step" - "You Wish": about a genie living a family, and "Teen Angel", about an angel. The problem was that these shows were not endearing as so many successful TGIF shows had been for years, and failed with the critics and audiences, 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 ABC Friday nights. ABC's "TGIF" lineup began to experience sagging ratings during the 1997-98 season in part due to the audience fracture from the "Block Party", which was enough to hurt "TGIF" even though the competing CBS block itself was a failure. Popular programs such as "Boy Meets World" and "Sabrina the Teenage Witch" started experiencing declining rating due strong competition from CBS's "Kids Say the Darndest Things", "Candid Camera" (successful follow-up replacements to the ill-fated CBS Block Party) and "Dateline NBC"; after eight years: ABC was no longer the top network on Friday nights. The new shows joined the lineup (both supernatural/fantasy-themed comedies designed to mesh with "Sabrina" on the lineup) lasted only a season (or less) before they were cancelled. "You Wish" was pulled in November while "Teen Angel" lasted until February. Save for a two-week run of "Hiller and Diller", ABC simply aired repeats of "Sabrina the Teenage Witch" and "Boy Meets World" for the rest of that season (at 8:00pm and 9:30pm respectively, before their new episodes). As part of a network-wide rebranding toward a simplified graphics package, ABC retired the traditional "TGIF" logo and phased out the theme song.
