Although the reviews for "The Judy Garland Show" were good, and she was on her best professional behavior throughout, the show was beaten in the ratings, virtually every week, by
Bonanza (1959) on rival network NBC. This, coupled with the fact that then-CBS President James Aubrey intensely disliked Garland, and didn't bother to hide it, ultimately doomed the show to a one-season run. Its failure is thought, by some, to be one of the major contributing factors to Garland's final tormented years and subsequent early death.
