Some television series are canceled after one episode, quickly removed from a broadcast schedule, or had production halted after their premieres. Such immediate cancellations are rare, and usually attributed to a combination of negative reviews, poor ratings, radical or controversial content, and circumstances beyond the network's control.

Purposely excluded from this list are pilots, premiere episodes produced primarily to be reviewed by network executives as proposed series, "backdoor pilots", pilot episodes shot in such a way that they can be aired as a regular episode of another series, and feature-length television movies produced to be broadcast as either an extended premiere episode, if picked up as a series, or as a distinct television movie. In any of those cases, the pilot was aired but its proposed series was not subsequently added to the programming, or the pilot was aired as a television movie after a decision not to produce a series.

Canceled after one episode The Dennis James Carnival (October 31, 1948) A variety show presented by CBS, The Dennis James Carnival showcased various vaudeville-style acts under the premise that host Dennis James was trying to keep afloat a carnival that he had inherited from his uncle. The reaction to the program was mostly negative, and its sponsor, General Electric, was dissatisfied with the carnival setting. A Variety article at the time noted that "this marked the quickest on-and-off commercial fade in young tele's history." Who's Whose (June 25, 1951) A panel quiz show hosted by Phil Baker that aired on CBS in which four celebrity panelists (Robin Chandler, Basil Davenport, Art Ford, and Emily Kimbrough) tried to determine which of three contestants was married to a fourth contestant. This show replaced The Goldbergs, which was dropped when its creator Gertrude Berg refused to fire the blacklisted actor Philip Loeb. While one source has classified this show as a television pilot, contemporary news accounts confirm that this was a series that was dropped by its sponsor (General Foods) after one airing. Turn-On (February 5, 1969) An ABC variety comedy series; a racier derivative of Rowan & Martin's Laugh-In, the show alarmed broadcast officials and sponsors who immediately perceived it as offensive because of its strong sexual and political humor. At least one station (WEWS-TV in Cleveland, Ohio) made known their cancellation of Turn-On as the program aired (and inspiring an urban legend that WEWS pulled the program after the first commercial break), and others on west coast delay refused to air it at all. ABC canceled the show before airing another episode. The Melting Pot (June 11, 1975) A BBC sitcom written by Spike Milligan, who also starred as Mr. Van Gogh, a Pakistani illegal immigrant in London, whom Milligan portrayed in brownface alongside John Bird.

(September 30, 1990) A comedy on British satellite channel Galaxy that spoofed American sitcoms of the 1950s and 1960s by featuring caricatures of Adolf Hitler and Eva Braun who live in matrimonial bliss until they become neighbours to a Jewish couple.

Australia's Naughtiest Home Videos (September 3, 1992) A spin-off of Australia's Funniest Home Videos hosted by Doug Mulray that depicted videos of sexual situations and other sexually explicit content (such as animal privates, people playing with condoms, and various wardrobe malfunctions.) Kerry Packer, the owner of Nine Network at the time, ordered the program to be taken down partway through its first and only episode while watching it, as he was so offended by its content, he phoned the network's master control and angrily demanded "Get this shit off the air!" Most stations pulled the sole episode at varying points, airing an episode of Cheers for the remainder of the timeslot. Public Morals (October 30, 1996) A Steven Bochco-produced CBS sitcom about a vice squad unit of the New York City Police Department. The cast included Bill Brochtrup, reprising the role of John Irvin, a recurring character on another Bochco series, NYPD Blue.

Despite being heavily promoted on Fox during the World Series, the show was axed on November 3 following low ratings. GSN revived the show in 2009 as The Money List, hosted by Fred Roggin; this iteration, the first GSN original to employ a returning-champion aspect, lasted nine episodes.

As well as being a quiz, viewers were invited to phone/text in views towards current events. However, earlier the same day ITV announced that transmission of the ITV Play channel was being suspended after that evening's programs as a result of an investigation into its premium-rate phone services. Despite this, ITV still decided to push ahead with the launch of the series. The following week, it was decided that the ITV Play channel would permanently cease transmission due to the numerous irregularities involving call-in/SMS quiz shows in the UK. Although ITV Play did continue as a limited service on ITV1 The Debbie King Show ended after only 2hours on the air. Quarterlife (February 26, 2008) An NBC broadcast version of the popular MySpace series, with an intent to air on Sunday nights following its debut as a stopgap solution to present some 'new' form of programming during that season's writers' strike.

Secret Talents of the Stars (April 8, 2008) A CBS reality talent show where celebrities competed by participating in talents that differed from their profession.

Osbournes Reloaded (March 31, 2009) A Fox variety show hosted by The Osbournes – Ozzy, Sharon, Jack, and Kelly. The remaining five episodes were immediately shelved because of a combination of bad reviews and several Fox affiliates (including the entire Raycom and Local TV LLC station chains) either airing the program in an early-morning timeslot or not at all because of content concerns. 1000 Ways to Lie (March 3, 2010) Spike's spin-off to the show 1000 Ways to Die was immediately canceled after its first episode due to very negative reviews and poor ratings.

Ford Nation (November 18, 2013) A talk show hosted by Mayor Rob Ford of Toronto and his brother, city councillor and future Premier of Ontario Doug Ford, on Sun News Network in Canada, initially indicated as being a weekly program airing Monday nights. The Ford brothers had been in the news because of an ongoing scandal involving a video showing the mayor smoking crack cocaine. Despite garnering record ratings for the fledgling news/opinion channel, the show was nonetheless canceled after a single episode, reportedly because of unexpectedly high production costs (the one-hour program was reported to have taken five hours to record and an additional eight hours to edit) and advertiser concerns about being associated with the controversial politicians. Network executives, as well as Doug Ford, would later claim that the program only had a one-episode commitment and was not necessarily intended as a long-term series."Ford brothers planning web series after turning down reality show offers from 'Oprah and Dr. Phil,' Doug says", National Post, November 28, 2013
