* ''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/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 a girl as the secondary lead, female Riders are few and far between. The first example is in ''Series/KamenRiderDragonKnight'' (Western adaptation of ''Series/KamenRiderRyuki'', using original footage to add to the story), which introduced the first official female Rider; "Kamen Rider Femme". She's the only girl out of thirteen Riders.
* ''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/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).
* ''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.
* 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.
* {{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]].

* Averted and inspected in ''RescueMe''. Janet Gavin and other women are major characters, and the presence of ''one'' woman in the firehouse warranted an entire subplot.
* An interesting case is the BBC's ''Series/RobinHood''. For the first four episodes, Marian was the only female character, not so much because of The Smurfette Principle, but simply because there was no other reoccurring female character 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. However, both Marian and Djaq were written out of the show at the end of Season 2, and replaced with [[AffirmativeActionGirl Isabella and Kate]]. Although Isabella had an important part to play in the narrative, Kate was simply the Token Girl amongst the outlaws, a task that involved [[SatelliteLoveInterest fan-girling Robin]], getting kidnapped every week, and [[TheLoad being a useless tag-along]].
* ''Series/{{Scrubs}}'' started off with two females (Elliot and Carla) out of a cast of six--later seven once [[AlmightyJanitor The Janitor]] was PromotedToOpeningTitles. Laverne started off as the only recurring female character until formerly one-shot Jordan became an AscendedExtra, but then [[spoiler: Laverne was KilledOffForReal in Season 6]]. Season 8 averted this, adding three recurring female doctors (Sunny, Katie, Denise) and two recurring non-meds in The Gooch and Lady, but [[ReTool the last season]] only had two female mains and one recurring, who only served [[FunnyAccent two]] [[MsFanservice purposes]]. There were several female guest stars throughout the series, but the vast majority were just [[GirlOfTheWeek girls of the week]] for J.D.
* Out of the four leads on ''Series/{{Seinfeld}}'', only one (Elaine) is a woman, and she was [[SixthRanger a late addition to the cast.]] All four do get roughly equal screen time, though.
* ''Series/SesameStreet'' has an almost evenly split human cast, but for a period had almost no female Muppets. Even now, there's only a few significant ones, such as the mild-mannered Prairie Dawn (and Betty Lou, who was actually the same Muppet), Snuffy's little sister Alice, and the more recent characters of fun-loving Zoe, earthy Rosita, and girlie-girl Abby Cadabby.
* Reversed in ''Series/SexAndTheCity'' which had no male characters ''at all'' in the main cast; even Big and Steve (the two most frequent recurring characters) appeared in rather less than half the episodes of the series. Carrie's friend Stanford, the next most frequent, showed up in less than a third of the episodes.
* In ''Series/{{Smallville}}'', the earliest version of the Justice League includes [[Franchise/{{Superman}} Clark]], ComicBook/{{Aquaman}}[=/=]Author, Cyborg/Victor, [[TheFlash Impulse]]/Bart, GreenArrow/Oliver, and Chloe. This defies some common expectations however, as she is TheSmartGirl and is, at that time, romantically involved with someone outside the group.
* ''Series/StargateSG1'' suffers from this: Samantha Carter is the only woman on the team (although there is a very prominent female doctor who eventually ends up [[spoiler:getting KilledOffForReal]]). Can be justified by the fact that, even in modern times, 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'':
** On ''Series/StarTrekTheOriginalSeries'', Uhura was a [[TwoferTokenMinority Token Twofer]] who was also relegated to the position of space phone operator. ''[[FairForItsDay For the time]]'', she was rather progressive, but... This was due to ExecutiveMeddling. The original pilot had a female ''second-in-command''. It's been said that Creator/{{NBC}} gave Roddenberry a somewhat 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."
** For a world with supposed complete gender equality, this applies to most ''Trek'' series. ''Series/StarTrekTheNextGeneration'' started with three women - after the security chief died, all that were left were in rather stereotypically feminine roles as the doctor and counselor. Recurring females were Keiko (botanist), Ogawa (nurse), Ro Laren and Guinan. Only the latter two were of any real importance, and the first eventually settled into the role of O'Brien's wife.
** Much improved in ''Series/StarTrekDeepSpaceNine'' which had a female first officer (Kira) and female science officer (Dax), though the number of women was still in the minority. Unfortunately, however, the science officer role was not [[spoiler:replaced after Jadzia Dax's death - the new Ezri Dax]] was another counselor.
** Further improved in ''Series/StarTrekVoyager'', with Captain Janeway (who later became admiral), Main Engineer TwoferTokenMinority Torres (who was Klingon, female and half Hispanic), and little girl-who-evolves-into-god Kes, who was later replaced by science "Überbabe" Seven of Nine. The main villain for the first two series turned out to be Seska, a manipulative Cardassian spy, and the surprisingly non-annoying child character was Naomi (her mom, originally a RecurringCharacter before falling OutOfFocus despite her daughter remaining prominent, was a scientist).
** ''Series/StarTrekEnterprise'' had a female first officer/science officer (T'Pol), and a female comm officer/linguist (Hoshi).
** Interestingly [[EqualOpportunityEvil villains don't suffer this problem]]: ''Series/StarTrekDeepSpaceNine'' had the Female Shapeshifter, and Kai Winn as [[BigBad Big Bads]] and the Dominion has plenty of female Vortas. The Borg equally have plenty of female drones and are led by the Queen. In ''Series/StarTrekTheNextGeneration'' there was Planet Angel 1, led by women and Tasha Yar's home planet, complete with Tasha's sister. There were the Duras sisters, aka ''The Magnificent Four.''
* Amanda Keller is the only female cast member on the Australian panel/game show ''TalkinBoutYourGeneration'', not counting female guest stars.
* The sitcom ''Series/{{Taxi}}'' only had Elaine Nardo, until late in the show's run Simka became a semi-regular.
* Both the U.K. and U.S. versions of ''Series/WhoseLineIsItAnyway'' feature four players, all of whom are almost always male. Only one episode in 18 series featured one male and three female performers. This is not helped by both Colin Mochrie and Ryan Stiles appearing in every episode of the last 11 series, meaning the best the women could achieve was parity with the male performers. Lampshaded in one episode during a game of ''Scenes From A Hat'' in which the scene was "Bad Times to Kiss Someone". Since all the players were male, when the game ended, Colin Mochrie asked if they could get some women on the show. This is a common issue on similarly structured comedy shows.
* {{Lampshade|Hanging}}d on ''Series/ThirdRockFromTheSun'', where the aliens, having learned their ideas about Earth from its popular culture, decided that only one of them needed to be "[[TheChick The Woman]]".
* Almost all {{Panel Game}}s contain one, or no, women.
** Only two episodes of ''Series/{{QI}}'', the Domesticity episode and the Girls and Boys episode, have featured two females on the same panel; this was lampshaded in the latter, which included a question on why there weren't more women as guests on the show (the excuse was that test audiences laugh less at female comedians). Out of approximately 87 different guests over 9 series, 21 of them have been female, and only 7 of those have made more than one appearance. Historically, Jo Brand has pretty clearly served the role of the token female, having appeared 27 times as of series I (the most appearances of any guest panelist, tied with Sean Lock). Sandi Toksvig, however, started appearing in at least two episodes a year as early as series G, and Sue Perkins has also started to appear more regularly (twice in series I, and will appear in three episodes in series J), making them the {{Affirmative Action Girl}}s of the show.
** Seems to have been changed for "J" series - "Jack and Jill" had two women and "Jam, Jelly and Juice" had an unprecedented female ''majority'' -- Jo Brand, Sue Perkins and Liza Tarbuck.
** The biggest offender is probably ''MockTheWeek'', since all four recurring panelists (out of six) are male and the host is as well, and has never featured more than one female comedian on the same panel; out of 51 guests to appear on the show, 16 have been women. In fairness, there is a paucity of female comedians already, so it's not necessarily the fault of the people who make the programmes.
** ''Series/ToTellTheTruth'' often averted this, with a 50/50 split of the 4 panelists. The guests on the show are a trio, all imitating the same person, but have been both females and males.
** Almost always averted in ''Series/MatchGame'' (at least the 70's versions). Brett Somers was nearly always the top middle spot, and there were usually two women (with Richard Dawson in the middle) on the bottom tier.
** The BBC recently announced a new rule that all their panel shows would have at last one female participant from now on, effectively making the Smurfette Principle a literal law.
* Pick any jury on any other talent show. So You Think You Can Dance: 2 men, 1 woman. America's Got Talent: 2 men, 1 woman. The Sing-Off: 2 men, 1 woman. The Voice: ''3'' men, 1 woman.
** ''SoYouThinkYouCanDance'' has fluctuated; Nigel and Mary are permanent judges, but others have come and gone, so on any given episode the third could be a man or a woman.
* ''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.
* Ann was the only female out of the five regular characters on ''Series/TheTimeTunnel''.
