MST3K FAQ -- What is this MST3K thing, anyway?


Q: What is Mystery Science Theater 3000?
A: It is a unique and widely influential comedy television program.

Q: What is its broadcast history?
A:  It first aired as a local program on KTMA-TV, a local UHF station (NOT, as is sometimes reported, a cable-access channel) in the Twin Cities (Minneapols-St. Paul, Minn.) area from November, 1988 to May, 1989. From November, 1989, to December, 1996, it was shown in the United States on the Comedy Central (hereafter abbreviated as CC) cable TV network (and its forebearer, The Comedy Channel). It then moved the Sci-Fi Channel cable network, where new episodes began running in the U.S. in February, 1997. Its series finale debuted on August 8, 1999. The last first-run episode on the Sci-Fi Channel ran September 12, 1999. Reruns of its final three seasons continued for several years on the Sci-Fi Channel, but ceased at the end of January, 2004.
Thirteen years went by. Then, series creator Joel Hodgson held what was, at the time, the most successful Kickstarter fundraising campaign for an entertainment entity ever. The result was season 11 (14 episodes streaming on Netflix), which debuted in April 2017. Another six-episode season debuted on Netflix in November of 2018. On Nov. 26, Hodgson announced that there would be no more new episodes on Netflix but insisted the series would find a new home.

Q: Was it only seen on televsion in the U.S.?
A: No. From January 1998 to September 2000, some episodes from the show's eighth and ninth seasons ran in England (and some sections of northern Europe and Southern Africa) on a channel called Sci*fi.

Q: Did it ever win any awards?
A: The series won the prestigious Peabody Award in 1993; it was nominated for eight CableAce awards over six years (but did not win), and nominated twice for an Emmy (but did not win). See
Award Nominations for more information.

Q: What was it about?
A: Although the details of its premise changed radically over the years, Mystery Science Theater 3000 was really always about one thing: making fun of bad movies.
Initially, the main character was Joel Robinson, a janitor at a top-secret research facility, Gizmonic Institute, who had been marooned on an orbiting space ship called the Satellite of Love (hereafter abbreviated as SOL) by two evil scientists, Dr. Clayton Forrester (hereafter called Dr. F.) and Dr. Laurence Erhardt. At first operating from within Gizmonic Institute itself, and later from a cave-like underground hideout called Deep 13, Forrester and Erhardt had an evil plan: They would force Robinson to watch one bad movie after another, in order to study how he would cope with such torture. Joel's only companions on the spaceship were four robots (often referred to collectively as "the bots") which he'd built himself: CrowTom ServoGypsy and a camera robot named Cambot, through whose mechanical eye we see the proceedings. While Gypsy attended to the details of running the SOL, Crow and Tom joined Joel in the ship's screening room, the Mystery Science Theater, as he watched the movies that were sent to him by the mad scientists.
Over time, as performers departed and others were brought in to replace them, there were changes in the characters and the premise. In the CC-era episodes, Dr. Erhardt went "missing" and Dr. F. hired goofy lab assitant TV's Frank. In the middle of the fifth season on CC, Joel managed to escape the SOL and was replaced, as Dr. F.'s guinea pig, by unsuspecting temp Mike Nelson. In the final season on CC, Frank was "assumed into second banana heaven" and Pearl Forrester, Dr. F.'s domineering mother, moved into Deep 13. In the final episode of that season, all the characters (except Pearl) were mystically transmuted.
When the series debuted on The Sci-Fi Channel (before it was renamed SYFY), Pearl was in charge, continuing to send Mike bad movies. Pearl acquired two sidekicks: a refugee from The Planet of the Apes named Professor Bobo and an omniscient superbeing (whose brain resides outside his skull in a small dish) known as Observer (but who was often called Brain Guy). (By this time, the entire original cast had been replaced with new performers.)
During that season, the SOL left Earth orbit and Mike and the bots visited a series of planets, with Pearl and her crew in a small space ship chasing them through space and, later, time. For the final two seasons of the series on Sci-Fi, Pearl and her crew made their way back to present-day Earth, and settled at Pearl's ancestral home, Castle Forrester, while Mike and the bots again orbited overhead.
In the Netflix seasons, the new subject of the movie-watching experiments was the resourceful Gizmonics employee Jonah Heston. Providing the torture was Dr. F’s daughter, Kinga Forrester. With her in a lab on the dark side of the moon were her assistant Max (aka TV’s Son of TV’s Frank) and many minions called “boneheads,” and an in-house band called The Skelton Crew.
In addition, two new robots were introduced: M. Waverly and Growler.
But despite the many changes in the series, essentially the same thing happens in each episode: After some brief preliminaries, Dr. F./Pearl/Kinga sends Joel/Mike/Jonah the movie and in response Joel/Mike/Jonah and the bots yell "Movie Sign!" and then rush to their places in the theater as we, the viewers, see Cambot's path through several strange hatchways to his place in the back of the theater. There, Cambot watches as Joel/Mike/Jonah and the bots take their seats. We can see their silhouettes, sitting in theater seats, at the bottom of our TV screens and, as they watch the movie, the three offered riotously funny commentary, satire and general heckling.
The comments from Joel/Mike/Jonah and the bots, about 700 per episode, are the real heart and point of the show. The comments vary a great deal, from scatological silliness and sarcastic needling one moment, to complex wordplay and obscure references the next.
In its TV years, the show ran two hours, enough time to show an entire horrible movie and sometimes a terrible one-reeler, as well. In the Netflix era, there are no commercials, so typical episodes run about 90 minutes. And three times (during KTMA through season 11, twice during season 12) during the movie, Joel/Mike/Jonah and the bots came out of the theater to the SOL's bridge for short comedy bits known as host segments -- tomfoolery which may or may not have had some connection to the film they were watching.

Q: Are there episode guides?
A: A list of episode titles is included with this FAQ. A more comprehensive episode guide is available on this site.
Yes, there are other episode guides. Foremost among them is the Amazing Colossal Episode Guide, written by the Comedy Central era cast. It was published by Bantam Books. It covers all the national episodes through season six and briefly previews season seven. For a complete look at season seven, written by the cast, is at
When the series moved to the Sci-Fi Channel in season eight, the cast continued examining each episode in a similar way, on the Sci-Fi Channel's Web site. The text of those episode guide pages are now hosted by Satellite News.
