* ''Series/TheBigBangTheory'' started with five main characters: the four male nerds, and TheChick who lives across the hall (Penny). As the series progressed, more and more female characters were added, until the main cast (four guys and their respective {{Love Interest}}s) has become a GenderEqualEnsemble.
* The FiveManBand in ''Series/CaptainPowerAndTheSoldiersOfTheFuture'' included Captain Power, Hawk, Tank, and Scout, all male. Sometime before the start of the show, they rescued Jennifer "Pilot" Chase from the Dread Youth, and she joined the crew.
* ''Series/TheDailyShow'' rarely has more than one female regular at a time, if that. Currently, the only female correspondents are regular Samantha Bee and the very irregularly recurring Kristen Schaal. The show's spotty record with women correspondents was {{lampshade|Hanging}}d when Kristen Schaal took over the show and declared Jon Stewart to be the new Senior Men's Correspondent: "Feel free to talk about men's issues. But don't expect to be on the show more than every four to twelve weeks or so." Creator/OliviaMunn has appeared multiple times, which may make her the third regular female correspondent. The show has since recruited Jessica Jones, so the situation is improving ''slightly''...
* ''Series/{{Dexter}}'': While there are other female officers, none of them seem to be as highly ranked as Debra Morgan or Maria LaGuerta, and the latter seems to be the only woman in a position of power, save the woman who was brought in to try and undermine LaGuerta's authority. The latter caved under the pressure of her personal life.
* ''Series/DoctorWho'', the Third Doctor episodes, set on Earth in a male dominated military organisation, used mostly guys, with main cast members being the Doctor, TheBrigadier, Benton, later Harry, and one female character; first Liz, who was replaced by Jo, who was then replaced by Sarah-Jane Smith.
* ''{{Series/Emergency}}'': Even today, firefighting is male-dominated. To their credit, episodes may feature female trainees or female doctors. Dixie, however, was the only female regular.
* ''Series/HawaiiFive0'' is a remake of classic ''Series/HawaiiFiveO'', which is about an elite squad of police in Hawaii. The remake {{Gender Flip}}ped Kono in order to have a girl among the lead characters.
* ''Series/HomicideLifeOnTheStreet'' began with only one woman, Detective Howard, in the main cast. That was a deliberate decision to reflect real-life homicide squads, which were dominated by men. As time passed, more women were added to the cast.
* During the fourth season of ''Series/{{House}}'', the title character Invokes this when he's was told he could only hire two doctors, instead of three. He has four prospects, two of each gender. He [[spoiler:kicks one of the women out, and tells the other, nicknamed "13", that he'd hire her if he had a slot]]. Later, his boss, Lisa Cuddy, informs him that he has to [[spoiler:hire at least one woman, and tells him to hire 13]]. Cuddy starts to walk away, then realizes that she had just [[spoiler:[[BatmanGambit given him the three doctors he wanted]].]]
* ''Series/HumanTarget'' began without any female characters, and planned to add a single female character in its second season. Averted by adding [[TwoGirlsToATeam two women to the cast,]] making it a 3:2 male-to-female ratio.
* The Principle is followed in ''Series/ItsAlwaysSunnyInPhiladelphia'' with their 5-person group. Lampshaded in "The Gang Solves the Gas Crisis", when the gang discuss their roles: Mac's the brains, Dennis is the looks, Frank's the muscle, Charlie's the wild card, and Dee's the useless chick.
* While it's standard for ''Franchise/KamenRider'' to have at least one girl as the secondary lead and a second among the villains, female Riders are few and far between. Even in series where the number of Riders gets into the double digits (''Series/KamenRiderRyuki'', its Western adaptation ''Series/KamenRiderDragonKnight'', and ''Series/KamenRiderGaim'' have about a dozen each), only ''one'' of them will be a woman (Femme, Siren, and Marika, respectively).
* ''Series/LandOfTheGiants'' has a cast of seven humans, [[TwoGirlsToATeam two of which are women.]] Betty was written out for part of the second season because actress Heather Young was pregnant, making Valerie the only female in a group of six.
* In ''Series/LondonsBurning'' there is only ever one female firefighter in Blue Watch at any one time. This is a [[TruthInTelevision reflection of reality]], as only 3.1% of operational firefighters in the UK are female. In 1986, when the series began, there were less than ten women in the London Fire Brigade. The issue was explored in the pilot movie, when the station gets its first female firefighter and the men initially react with hostility.
* Inverted on ''Series/TheLWord'' where the vast majority of the ([[LoadsAndLoadsOfCharacters very large]]) EnsembleCast is female and there are only ever one or two major male characters at any time.
* ''Series/{{MASH}}'' averts the principle by having many female nurse characters on the cast, even if they aren't the focus of the episode. Gender issues related to the Smurfette Principle were explored in the show -- most notably when a male nurse is the victim of gender discrimination, having been made a private when all other (female) nurses were commissioned officers.
* ''Series/MissionImpossible'' (both the original and revival) never had more than one female regular at a time (though missions could and did have more than one female agent involved) - the original had Cinnamon in the first three seasons, then a revolving door of replacements in season four, Dana in season five, and then Casey for the final two seasons; in the revival Casey came first, and she was replaced by Shannon.
* ''Series/MockTheWeek'' has two teams of three panelists (two of which are guest panelists) and one host. The three regulars are all male, and the relatively few female comedians means it is hard to get more than one female guest panelist.
* ''Series/MontyPythonsFlyingCircus'' featured almost no women, because most of the roles were played by the same six (male) actors anyway, regardless of gender. By their own admission, the Pythons brought in women like "[[SixthRanger Seventh Python]]" Carol Cleveland only when they needed a female character to actually be attractive, otherwise, they'd just get into drag. Both Python precursor series, ''Do Not Adjust Your Set'' and ''Series/AtLastThe1948Show'', featured five person casts consisting of four men and one woman.
* The only major female Muppet is Miss Piggy, a glamourous diva. When she was first introduced, she was a minor character. The large cast of ''Series/TheMuppetShow'' is male-dominant, but this may be due to its slapstick nature (Miss Piggy, for example, rarely takes any of the slapstick, but she certainly dishes it out when provoked). Furthermore, the regular cast used to include other female characters, such as Janice and Hilda, but both became much less prominent after Hilda's puppeteer quit and Janice's puppeteer died, leaving Piggy. Janice herself rarely appeared outside of her FiveManBand (The Electric Mayhem), of which she was TheChick. There have been a few other female Muppets, but their tenure is either short-lived; or they're one-off characters. A notable example is Annie-Sue Pig; a young ingénue and foil to Miss Piggy. Her appearances declined considerably after the 3rd season, although she did still appear from time to time. A number of the [[AmbiguousGender ambiguously-gendered]] monsters are noted in background material as being female; but there is no clear indication of this on the show. This applies to the puppeteers as well; in the first season, there were seven puppeteers, and only one (Eren Ozker) was a woman. Ozker & John Lovelady left after Season 1, so they held auditions for a new female for Season 2, with Louise Gold getting the part (although she was uncredited for the season). In Season 3, they hired another female puppeteer (Kathryn Mullen) but also hired another male (Steve Whitmire) making it 6 guys, 2 girls. Also, in relation to Miss Piggy & Janice, they were (and still are) performed by males. Yeah.
* ''WesternAnimation/MuppetBabies'' is a SpinOff from ''Series/TheMuppetShow'', which would have imitated the parent series by having Miss Piggy as the only female character, except they added Skeeter, Scooter's [[HalfIdenticalTwins "identical" twin]], to add a second female to the main cast.
* ''Series/MythBusters'' generally has Kari Byron as the token female. This hasn't always been the case, however; Mythterns Christine and Jess often added a second female to the group, and the earlier episodes with the Build Team had Scottie Chapman as the third member after Kari and Tory. Grant only came on board after Scottie left the show, leaving the cast with Adam, Jamie, Tory, Grant, and Kari (plus Buster).
* ''Series/{{NCIS}}'' stars a set of four investigators, only one of which is female at any one time. They do have Abby, a lab tech who is one of three characters who has been in every episode (the other two being Gibbs and Dinozzo).
* In the second season of ''Series/PrisonBreak'', [[EnsembleDarkhorse Sara Tancredi]] is the only female character on the main cast, since Robin Tunney (who played Veronica in the previous season) decided to leave the show. [[DarkActionGirl Gretchen]] and [[SpicyLatina Sofia]] were later added to the main cast in season 3 to avert the principle.
* In ''{{Series/QI}}'', one host asks questions of four panelists (three guests and one regular). Rarely is there more than two female guest panelists, and often none. Jo Brand finds herself as representing the Smurfette Principle on the show on a regular basis, and so have Sandi Toksvig and Sue Perkins.
* ''Series/{{Raumpatrouille}}'':
** Crew of the ''Orion'': At the beginning of episode 1, the crew consists of four men and one woman, but Lieutenant Tamara Jagellovsk of the Galactic Security Service is assigned there during the events of the episode, changing the dynamic to TwoGirlsToATeam. Lt. Jagellovsk is not a crewmember, and leaves during episode 7, restoring the ''Orion'' cast to the "one woman in a team of five" dynamic.
** Crew of the ''Hydra'': General Lydia van Dyke is the only woman belonging to the crew of the ''Hydra'' and the only woman to participate in the high-command-plus-government-representative conferences.
* {{Zig Zagged|Trope}} in ''Series/RedDwarf'', which usually has an all-male cast of Holly, Kryten, Rimmer, Cat, and Lister. But Holly had a sex change for Series III, IV and V. After Holly is rendered male again, Kochanski is added to the crew, and is the only female of the ''Starbug'' for most of VII and VIII. For part of ''Back to Earth'', the hologram Katerina takes up the female role, [[spoiler:Kochanski being assumed dead]].
* The primary cast of ''Series/RescueMe'' features a dozen different firefighters on "62 Truck", but only Probationary Firefighter Laura Miles is a woman. The non-FDNY characters round out the gender dynamics some, but there's only ever one woman on the 62 Truck.
* The BBC's ''Series/RobinHood'' was rather stuck. For the first four episodes, Marian was the only female character because there was no other reoccurring female characters in the legends. This was solved with the introduction of Djaq, a SweetPollyOliver in the {{Gender Flip}}ped role of "The Saracen", who contributed her skills as a physician and scientist to the team, leading the series to a more permanent TwoGirlsToATeam dynamic that stayed even when Marian and Djaq were written out.
* ''Series/SesameStreet'' maintains an almost [[GenderEqualEnsemble evenly split by gender human cast,]] but for a long period had zero female Muppets. Many female muppets were around before ''Sesame Street'' made a large push to get a popular one, which was [[http://www.nytimes.com/1993/08/19/garden/on-the-set-with-zoe-this-monster-is-a-girl.html 1993's Zoe.]] By now, the Smurfette Principle on the show is fully averted, even if the male muppets still outnumber the female muppets.
* In ''Series/{{Smallville}}'', the earliest version of the Justice League includes Clark, Arthur, Victor, Bart, Oliver, and Chloe. This group defied FiveManBand, and even allowed Chloe to be romantically involved with someone outside the group.
* ''Series/StargateSG1'' includes only a minority of female characters: Samantha Carter is the only woman on the team (although there is a recurring female doctor who eventually ends up [[spoiler:getting KilledOffForReal]]). Even during production, the military is hardly the most gender equitable of places. Due to ExecutiveMeddling, a sexy female thief gets added to the team in the final two seasons. ''[[Series/StargateAtlantis Atlantis]]'' is a lot better at balancing out the roles.
* ''Franchise/StarTrek'': For a world with supposed complete gender equality, this applies to most ''Trek'' series.
** On ''Series/StarTrekTheOriginalSeries'', the bridge crew had only Uhura, who was a [[TwoferTokenMinority Token Twofer]] and was also relegated to the position of space phone operator. ''[[FairForItsDay For the time]]'', it was rather progressive to have even one woman on the bridge. The full crew contained more women, but Uhura was the only female bridge crew member.
** The original pilot for ''Series/StarTrekTheOriginalSeries'' ("The Menangerie") used a TwoGirlsToATeam dynamic, one of which was a female second-in-command. It's been said that Creator/{{NBC}} gave Roddenberry a SadisticChoice: either keep the female second-in-command or keep Spock, but not both. Years later, Majel Barrett would quip that he "kept the Vulcan and married the woman, 'cause he didn't think Creator/{{Leonard|Nimoy}} would have it the other way around."
** ''Series/StarTrekTheNextGeneration'' started with three women - [[TwoGirlsToATeam two who are bridge crew]] - and after Tasha Yar died, there was only Counselor Troi on the bridge. Recurring female characters at least existed, defying the trope for the entire ship.
** ''Series/StarTrekDeepSpaceNine'' features only one Starfleet officer: Jadzia Dax. Since the space station is owned by a partnership of Bajorans and the Federation, the primary cast is TwoGirlsToATeam, with Kira Nerys acting as Sisko's second-in-command.
** Almost {{averted|trope}} in ''Series/StarTrekVoyager'', where Captain Janeway is the only female bridge member for many seasons. Chief Engineer Torres [[TwoferTokenMinority (who was Klingon, female and half Hispanic)]], Kes and Seven of Nine are all part of the main cast, and are stationed on the bridge for part of the time.
** ''Series/StarTrekEnterprise'' finally [[AvertedTrope averts the trope]] with TwoGirlsToATeam. The bridge crew consists of several men, female first officer/science officer (T'Pol), and a female comm officer/linguist (Hoshi).
* ''Series/SuperSentai'' typically uses a FiveManBand of four guys and one girl. The western adaptation (''Series/PowerRangers'') typically changes it by ShesAManInJapan to create TwoGirlsToATeam.
* ''Series/{{Taskmaster}}'': Hosts Alex Horne and Greg Davies ask questions from a panel of five contestants. The only female contestant is Creator/RoisinConaty.
* The sitcom ''Series/{{Taxi}}'' had lots of taxi drivers, but only Elaine Nardo, a single-mom/art-gallery receptionist until Season Four introduced Simka Dahblitz-Gravas, a LoveInterest and DistaffCounterpart to Latka. Simka was a recurring character until finally joining the main cast permanently in Season Five, changing the {{ensemble}} to TwoGirlsToATeam.
* Ann was the only female out of the five regular characters on ''Series/TheTimeTunnel''.
* ''Series/ThirdRockFromTheSun'' features four aliens sent to Earth to study mankind, after having learned some about Earth from its popular culture. They maintain occasional communication with the (male) "Big Giant Head", who decided that only one of the four sent to Earth needed to be "[[TheChick The Woman]]".
