ABC's Weekend Special had been on the air for 8 years when CBS finally decided they wanted a show like that.
CBS Storybreak, however, lacked the staying power of Weekend Special, as it lasted a grand total of 8 years over two runs (1985-8, 1993-8). Like Weekend Special, Storybreak aired at lunch time, but some CBS affiliates were reluctant to carry the show at first, believing they would be better served continuing to collect ad revenues for themselves for airing syndicated programming.
Bob Keeshan, given an opportunity to do something other than Captain Kangaroo, served as host for the first run, which would mark the end of his 30+ year association with CBS. When the series returned in 1993, actor Malcolm Jamal-Warner (The Cosby Show) replaced Keeshan, and taped new intros and bumpers.
Hanna-Barbera's Australian studio produced the animation, as sister company Ruby-Spears was a primary supplier for ABC's Weekend Special. Notice how NBC stayed out of the fray?
Anyway, I never did see Storybreak, so there won't be a rating. We'll serve up an adaptation of Sandy Clifford's The Roquefort Gang, featuring the familiar voices of Len Weinrib, Maurice LaMarche, and John Stephenson, among others.
