all of the TGIF sitcoms were replaced with Beatles songs, regardless of the individual shows' plot with the exception of Boy Meets World, which used a song by The Monkees as its theme that week (as the episode featured a guest appearance by the group's members).

After a couple years with nearly the exact same lineup, ABC finally changed up its Friday night lineup to jump start the fading TGIF by holding Step by Step and Hangin' with Mr. Cooper on the backburner (until the Spring of 1997) and launching two new shows that were bookended by popular veterans Family Matters and Boy Meets World. The first was Sabrina the Teenage Witch, a fantasy sitcom based on the Archie comic book character that starred Melissa Joan Hart, who had made her name earlier in the 1990s as the star of Nickelodeon's Clarissa Explains It All.
