By the early 1980s, the few new variety shows being produced were of remarkably poor quality (see, for instance, the infamous "Pink Lady and Jeff"), hastening the format's demise. A brief revival of the genre arose in the late 1980s and early 1990s. Variety shows from this era included "Dolly" (starring Dolly Parton), which ran for 23 episodes on ABC during the 1987–'88 season; "The Tracey Ullman Show" which aired on Fox from April 1987 through May 1990; a revival of "The Smothers Brothers Comedy Hour" from 1988 to 1989; a revival of "The Carol Burnett Show", which was broadcast by CBS for nine episodes in 1991 (following up on "Carol & Company" on NBC the previous year); and Showtime's "The Super Dave Osborne Show" hosted by Bob Einstein from 1987 to 1991. By the 1990s, networks had given up on the format; after initially promising Phil Hartman his own variety show, NBC backed out of the agreement believing a variety show could no longer succeed.
