And here, according to Wikipedia, is the list of all shows cancelled after one episode...
Australia's Naughtiest Home Videos
1993 comedy series spun off from Australia's Funniest Home Video Show, hosted by Doug Mulray. This show was actually cancelled during its first episode. Nine Network owner Kerry Packer purportedly personally telephoned the station, telling them to "Get that




off the air". After a commercial break, a re-run of a Cheers episode was aired instead. It is understood that Mr Packer was alerted to the content of the program by several of his personal friends.
Co-Ed Fever
1979 comedy that attempted to imitate the then successful National Lampoon's Animal House. The pilot was aired as a "special preview" of the then coming season, and the series was canceled in the interim between this airing and the actual date when the series was due to be aired.
Dot Comedy
2000 comedy show on ABC featuring humorous material found on the Internet.
Heil Honey I'm Home!
1990 comedy show on British Satellite Broadcasting in which Adolf Hitler and Eva Braun have survived the war and are living in 1950s New York City next door to a Jewish couple. The show was cancelled after the first episode despite the fact that the rest of the season had already been filmed.
Lawless
1997 action series starring Brian Bosworth as a private investigator.
The Oblongs
2001 comedy, and a somewhat special case, in that it aired a full season on The WB and is rerun on Cartoon Network's Adult Swim in the United States; but when shown on Australia's Channel Nine in 2003, the network pulled the episode mid-airing, thus arguably qualifying it for this list.
South of Sunset
1993 private detective show on CBS starring Glenn Frey. This was the first US-produced series to be cancelled after one episode since 1969. The remaining five episodes eventually aired on the VH1 cable network a year later.
Transformers: Zone
1990 Japanese anime that was cancelled after one episode, and the remainder of its story was published in a magazine.
Turn-On
1969 comedy/variety show canceled for being a terrible derivative of Laugh-In. Although not the first series to be immediately cancelled, Turn-On is generally considered the best-known example.
The Will
2005 reality TV show on CBS in which family members and friends competed to be named the beneficiary of a will.
Who's Your Daddy
2005 reality TV show featuring a contestant who was adopted trying to guess which of eight men is her biological father.
You're in the Picture
1961 game show starring Jackie Gleason; notable in part for Gleason going on the air the next week and saying of the show: "Honesty is the best policy. We had a show last week that laid the biggest bomb! I've seen bombs in my day, but this one made the H-bomb look like a two-inch salute." Technically the series wasn't cancelled, but rather Gleason renamed it The Jackie Gleason Show and it became a talk show for the remainder of its limited run.
