3. AllAmericanPearsonFremantle buys G-T formats, but gives us TPIR94, CS2001 and 98 MG revival (only FF resembles the original).
Actually, the 1994 TPIR pre-dated All-American's acquisition of Mark Goodson -- it's Paramount's fault, in that case.
7. Bill Cosby's You Bet Your Life - what seemed to be a sure thing for success - revival flops after one season, 1992-93
I recall that the show was cancelled early in the season, but Bill still had faith in the program, leading to its decision to cancel the show, but to keep it in production for a full season. While it was a rather funny show full of Cosby's wit, once it's cancelled, it becomes "damaged goods" -- stations either dropped it, gave it to a low-rated station, or even moved it to late night. In that last case, I recall a "Saturday Night Live" sketch from around that time, where a TV station announced that they were leaving the air for the night, but first, Cos' YBYL.
9. Nickelodeon has game show hits (Double Dare, which aired on Fox as Family Double Dare and in syndication, and others) but cuts the shows in favor of animation.
And even taht department, they favor to promote the heck out of the newer Nicktoons, while leaving the older and weaker Nicktoons off the air. And don't get me started about their volatile schedule. Those wanting to watch old episodes of Rocko or Angry Beavers on Sunday afternoons will understand.
