Sesame Street is such a strong leader that it inspires rivals and hurts its own viewership.
CSI precipitated a host of forensic science shows involving (to quote the show) "beautiful people doing high-tech crime work", even to the point that shows not inherently about forensics now spend more time on the subject (e.g. the medical examiner on Law & Order: Special Victims Unit).
CSI itself was inspired by an earlier wave of forensic-science documentaries, on channels like Discovery and Court TV.
The latter which tend to always have a blunt English guy, a sympathetic woman, and some third wheel, most likely a 'cool' guy.
The heavily character-driven, strangers-in-a-strange-land suspense formula of Lost inspired plenty of other shows, such as Invasion!, Jericho, Heroes, Surface, and Threshold. Many of which were cancelled before they barely even began to delve in their Myth Arc. Coincidentally, there is a Lost episode titled "Follow the Leader."
After Lost's finale, a slew of new shows have started claiming to be "the next Lost" in order to round up the Lost fans looking for something new to watch. FlashForward (2009), V, and The Event have both tried rather unsuccessfully to take Lost's place and new programs Stargate Universe, Riverworld, and Terra Nova made the attempt as well.
The concept was sent up in a MADtv skit. "You'll be asking yourself questions like, 'Who's the girl with the glasses, and why does she have scales on her leg?'"
Lost was blatantly copied (in the vein of an Asylum film) by 2010's "Dark Island". A science team (totally not the freighties) is sent to deal with zombies and a SMOKE MONSTER on a mysterious island.
J. J. Abrams had already created a fair amount of the concept with his earlier Alias.
This goes all the way back to The Prisoner, and maybe even before.
One might argue Friends was one of the ensemble Sitcoms inspired by Seinfeld. As George says in one scene set in Monk's coffee shop, "Every sitcom today just has four morons sitting around telling each other how bad their day was." Another would be Mad About You which co-creator Paul Reiser pitched to NBC as "Seinfeld, but Married".
These three shows' open approach to sex has led to a more frank tackling of sexual situations on TV comedy rather than being just the basis for one or two dirty jokes (fittingly, sex lost its taboo status during this time). There are some shows that still do that however.
Among the Friends-inspired: Partners, a rather similar show about the lives, loves, and careers of 20somethings; Coupling (the British Friends); and later possibly How I Met Your Mother.
This is an odd case, as three of the imitators—VR Troopers, Masked Rider and Big Bad Beetleborgs—were all made by Saban as a way to leech off Power Rangers, which they also made. Masked Rider was a total flop and the other two were only mildly successful.
Beetleborgs absolutely TROUNCED Power Rangers in ratings and toy sales for both seasons it aired, and was only canceled due to exorbitantly high production costs and a lack of additional source footage. Justin got introduced to Power Rangers Turbo in order to leech off the success of its own imitator; this didn't work so well.
Disney is actually quite the repeat offender. Apparently it comes written into all of their female tweenage stars' contracts that they will get to release a high-profit CD of pop music within two years of the show's inception, complete with overpriced tie-in merchandise. For examples, see Hilary Duff, Hannah Montana, and The Cheetah Girls.
Before that was Annette Funicello and Hayley Mills, in The '60s. "Tall Paul" or "We Belong Together", anyone?! Uncle Walt himself began the whole shpiel, to capitalize on the success of Ricky Nelson.
Disney also has developed a tendency to go with whatever is popular on Nickelodeon and release their own version. Even when what they make is not a blatant, obvious copy, shades of it are still there. Ant Farm has an entirely different premise from True Jackson, VP, but the main characters are both black, speak the same way, and have almost identical mannerisms.
Despite being cancelled years ago, Jackass still has copies around, including Dirty Sanchez, Crazy Monkey, Rad Girls, and the Finnish series Extreme Duudsonit (which actually came before Jackass).
Even the stars of Jackass have started to clone their own show, with Steve-O and Pontius' "Jackass, but with animals" show Wildboyz and Bam Margera's "Jackass, but a reality show" Viva La Bam.
Some of the Jackass guys helped produce an English language version of Extreme Duudsonit - which they list as the primary influence for Jackass - for an American audience. The resulting show - called The Dudesons - was cancelled by Spike TV after only a couple of episodes, mostly because people didn't watch it because they thought it was a spineless Finnish Jackass clone.
Jackass itself was derived in part from the character off Super Dave Osborne, a parody of 1970s stuntmen like Evel Kneivel, played by comedian Bob Einstein. Einstein himself detests Jackass, pointing out in this interview that Jackass is tragically easy to imitate, while the stunts he pulled were a lot harder for viewers to copy.
There's also Web Soup, which shares a lot of the same setup as Tosh.0. (with Chris Hardwick instead of Daniel Tosh. Funny thing, though; the first episode only aired four days after Tosh.0's, making it unlikely that there was any intended plagiarism.
The X-Files inspired a number of series featuring alien invasions and supernatural hoohah, such as Dark Skies.
The success of The X-Files mythology perhaps also inspired series, such as 24 and Lost, that used serialized storylines, which in turn led to more serialized thriller shows such as Prison Break, Kidnapped, Vanished, Reunion, and Heroes, along with a few that also borrowed the alien invasion premise as well: Invasion!, Surface, and Threshold. Most of these series failed due to people being unable (or unwilling) to keep up with so many different ongoing stories — and also due to generally being not very good.
There were tons of shows in Japan of this type long before X-Files. In 1964, we have Ultra Q (the predecessor of Ultraman), greatly involving Kaiju. Then, in 1968, two series: Operation Mystery (probably the most like X-Files out of the three) and Mighty Jack (the movie was lampooned in MST3K). All three are made by the same company.
While the degree to which Star Trek: Deep Space Nine was inspired by/ripped off Babylon 5 is controversial (to say the least), there is less doubt that the former's "Dominion War" arc was inspired by the latter's intricate Myth Arc (although only the most rabid partisans of Babylon 5 would claim that Deep Space Nine ripped it off outright). The B5 myth arc was in turn inspired by story arcs used in foreign television series, and combining it with a long-time comic-book fan's love of continuity to take the concept Up to Eleven.
The success of the pithy, sarcastic Judge Judy spawned a whole slew of pithy, sarcastic judge shows: Judge Mathis, Judge Joe Brown, Playboy Channel's Judge Julie etc. Even the venerable The People's Court replaced Judge Wapner with sarcastic, saucy Latina Judge Marilyn Milian (after brief stints by former New York Mayor Ed Koch and Judge Judy's husband). To be fair, Jerry Sheindlin was a judge in his own right.
The People's Court revival was originally planned as a vehicle for Lance Ito, who wisely declined.
It also had an influence on the revival of Doctor Who, although Rose did not engage in any roundhouse kicks.
It also helped kick off a revival of vampire movies, particularly Underworld.
Twilight followed the trend of "special human girl and vampire fall in love" but tragically misses the point where Angel and Buffy realize that their relationship will never work out and end it.
It even influenced cartoons - Kim Possible is clearly modelled after Buffy's basic plot structure, and the heroine is even a cheerleader.
The day Agents of S.H.I.E.L.D. premiered on ABC to massive ratings, Fox ordered Gotham. And then after Gotham premiered to massive ratings, Syfy ordered Krypton, a similar prequel built around the Superman mythos.
Shortly after it was announced that NBC had ordered a DC Comics sitcom called Powerless, ABC announced that they were planning their own Marvel sitcom.
During the lead-up to the premier of Luke Cage, it was announced that Fox had ordered a pilot for a TV show based on Black Lightning, another former urban Blaxploitation superhero. What makes it interesting is that the show had apparently been floating around for a while, but it wasn't picked up until the rave reviews for Luke Cage started pouring in.
Merlin is quite an astonishingly direct emulation of the premise and format of Smallville, to the point where most of the characters are even expys of the parent show's cast. Not that that's to say it's a bad show, just that it's clearly following the leader.
Anytime a particular weapon or design in Robot Wars became really successful it would be heavily copied in later seasons. Some examples;
TRACIE from season 1 was designed to run both ways up. The feature caught on and was used by a lot of robots in later wars including Tornado and SMIDSY.
Flippers, which briefly became something of a Game Breaker until people worked out how to deal with them. First used by Recyclopse in season 1, but made really popular by 1: Cassius (Recyclopse's successor) which used its flipper to right itself when turned over (this later became known as the self-righting mechanism, or SRIMECH) and 2: Chaos 2, winner of the 3rd and 4th season which had a very powerful flipper (and also was the first to flip another robot over the fence).
The SRIMECH itself; while originated as an Improbable Use of a Weapon (many robots used flippers, or other weapons), some later robots had separate self-righters that did not double as weapons.
Crushers, first introduced by Razer in the second wars though these didn't start to catch on until the 5th season when the weight limit was increased.
Spinning discs, first used by Hypno-Disc in the 3rd wars and produced heavy amounts of damage, however imitators rarely managed to succeed at this.
The revival of Doctor Who has led to attempts at bringing back several other shows, including Survivors and Rentaghost, as well as to the recreation of the "Saturday evening drama" slot, evidenced by Primeval.
And in America, it hasn't brought back anything, it's simply added to the long-running "Friday night Skiffy" slot which has been going for at least 15 years...around the time the Saturday evening drama seemed to go away for a bit in England.
It also led to a string of TV shows in which classic British heroes were reinvented (Robin Hood, Merlin, Sherlock, etc). Like Doctor Who, some of these shows have been well-received. Others, not so much.
The continued success of the Doctor Who revival in The New '10s appears to have been the primary catalyst for no less than four debuting shows in the 2016-17 U.S. broadcast television season featuring timey-wimey premises: Time After Time (ABC), Making History (Fox), Timeless (NBC), and Frequency (The CW), with the more recent successes of Outlander and Legends of Tomorrow (the latter even features Who alumni in its cast) further encouraging the trend.
Part of the reason for the clones not getting better than cult status may be that the Degrassi writers were beginning to get weary with their creation, and doubly weary with imitations of it. The Best Years, a clone created by the head of the Degrassi writing staff, was full of Take That! against Degrassi, and the Crossover commercials quickly changed from grimly earnest to Adam Westing.
Britannia High is just High School Musical except, as the name suggests, set in Britain. It fared rather badly - so badly in fact that even among its target demographic, it lost in the ratings war to Antiques Roadshow.
USA released Psych, a series about a hyperobservant amateur who solves crimes by pretending to have psychic powers. Shortly after it became a hit, CBS released The Mentalist, a series about a hyperobservant solves crimes by pretending to have psychic powers. In fairness, the show is a lot angstier.
One episode of Psych actually namechecked The Mentalist referring to it as a "carbon copy", and Shawn himself is a fan of the show, though he prefers people not confuse him with that fake psychic.
Another episode has Shawn saying that he has an idea about a psychic show & they should pitch it to CBS...
However, Psych itself followed (and eventually replaced) another USA show, Monk, which also featured a freelance Bunny-Ears Lawyer detective.
It's been pointed out that both shows, along with several others, including the aforementioned Monk, Law & Order: Criminal Intent, and even House and Life are all really based off of Sherlock Holmes; an extremely intelligent yet quirky detective solves mysteries by noticing the little details. The only things that Psych and The Mentalist specifically have in common are the "fake psychic" thing and being set in California, and both shows use both of those elements very differently.
USA also released Burn Notice, a series about a small group of quirky ex-special operatives who use their skills to help out the little guy. Shortly after it became a hit, TNT released Leverage, a show about a small group of quirky ex-criminals who use their skills to help out the little guy.
It's worth noting that the Leverage page used to have "Spiritual Successor" listed on it with no less than 4 examples, and both the Burn Notice and Leverage pages compare the shows to The A-Team.
Not sure how it goes in the States, but in Australia, there seems to be a legal requirement for reviewers to describe Burn Notice as "The A Team for grownups'".
There's now a surge in intelligence community comedies (Covert Affairs, Chaos), which according to the LA Times was started by Burn Notice.
The appeal of Burn Notice and Leverage is what also probably led to the creation of White Collar.
After Caiga Quien Caiga became famous, "Los Raporteros" began fashioning themselves after Mario and co., with black suits, black glasses, an edgier song ("Como Estamos Hoy, Eh", replacing the softer and more rhythmical "Abarajame La Bañera") and more controversial lyrics.
The success of Gran Hermano prompted a wave of Argentinian reality TV shows, including Solos en la Casa, El Bar and Survivor Operación Robinson.
The success of Rebelde Way prompted more Argentinian tween shows like Patito Feo, Casi Angeles and Floricienta Also this, combined with the success of High School Musical, prompted the Argentinian remake of that movie.
After Perdona Nuestros Pecados got canned, a slew of imitators tried to take its place. However, most of them missed the point and mutated into talk shows. Only one of them, Ran 15, actually does what PNP used to do.
100% Lucha was created to fill the void after the cancellation of Titanes en el Ring.
Ghost Hunters inspired a wave (different from the wave of paranormal slasher horror movies) about paranormal investigations. Even the History channel got into the act.
It was unheard of to film a sitcom in front of a live audience until the success of I Love Lucy. The production of I Love Lucy all but innovated everything you'll see in every sitcom since. The fact that it was filmed is what preserves it as the oldest television product that most Americans have ever seen, since it avoided the pitfalls of using videotape which would be wiped and reused later (since it was very expensive, and many networks were wiping videotape into the 1980s), or only existing today in the form of crude kinescopes (where a motion picture camera was pointed at a television monitor) that have little replay value today.
The raging success that was High School Musical was followed by a slew of easily-marketable Disney Channel movies—often featuring the channel's newest stars (Ashley Tisdale, Corbin Bleu, the Jonas Brothers etc). Meanwhile, Nickelodeon tried to get into the act with Spectacular!, a musical movie about a choir (who, for a change, performed "Eye of the Tiger") who failed because their leader insisted on doing the same old routines. The decision to cast Tammin Sursok (a soapie star best known in Australia - and to fans of The Young and the Restless, plus this was before Pretty Little Liars) may not have been the greatest idea...
Ironically, HSM is basically Grease: The Next Generation.
Also MTV made the musical The American Mall. The less said about it the better.
You can also follow a very straight line connecting American Idol (specifically, when after a few seasons it became largely beholden to the voting whims of tween girls) to High School Musical to Glee.
The success of Dirty Jobs and Deadliest Catch on Discovery Channel spawned a host of interesting/dangerous jobs Reality TV shows like Ice Road Truckers (History Channel), two about extreme loggers, one about lobstermen (although that might be the originator since a special about lobstermen was essentially a test run for Catch) and Swords, which is about sword fishermen.
Perhaps attributable to the success of Monk, a lot of "quirky investigative genius solves crimes" shows have popped up of late: Psych (the guy is a fake psychic), The Mentalist (the guy is a former fake psychic), Lie to Me (the guy is a Living Lie Detector), Bones (quirky forensic scientist), Raines (the guy is haunted by hallucinations of the murder victims until he solves the case), Body of Proof (Insufferable Genius medical examiner), Castle (the guy is a wisecracking mystery novelist), and arguably to a lesser extent Dexter (the guy is himself a serial killer) and Pushing Daisies (the guy can bring the dead back to life).
The protagonist of the new Body of Proof on ABC has been criticized for being a combination of House (brilliant doctor with mild pain problems who is usually right) and Temperance Brennan of Bones (quirky forensic scientist with poor social skills).
The success of Twilight and The Vampire Diaries may have led CW to remake Beauty and the Beast, an Urban Fantasy centered on the relationship between a human woman and a beast-man who has trouble controlling his violent impulses.
Survivorman was about survival expert Les Stroud being dumped into the wilderness and trying to make his way to civilization before a Rescue Chopper comes to him in a given period of time. Man vs. Wild features survival expert Bear Grylls being dumped into the wilderness and trying to make his way to civilization. There were several differences between the two shows, such as Bear's camera crew vs. Les toting around several dozen pounds of cameras, and Les pragmatic approach to Bear's more extreme version. M v W also stages situations for Bear to demonstrate unlikely or worst-case techniques. These points are explained in more detail on both pages.
Life After People became the highest rated program in the history of The History Channel when it aired in January 2008. Just a few months later, The National Geographic Channel aired Aftermath: Population Zero which was practically the exact same show. Both shows are practically the television adaptation of the explosively popular book "The World Without Us," published in 2007.
Food Network has started making a large number of culinary-themed reality shows where one contestant is eliminated per show (or per round, in self-contained shows), a la American Idol. In addition, they now have a new show called Chefs vs. City, which is single legs of The Amazing Race with culinary-themed challenges, only two teams, in a single U.S. city, and the prize is "bragging rights."
Not long after Restaurant Stakeout, a show where the host and restaurant owners use security cameras to figure out which employees are tarnishing the reputation of the owners' restaurants made its debut on the channel, Mystery Diners, a show with a nearly identical premise except with a shorter runtime and considerably more dramatic tone, turned up.
It seems more than likely that the remake of V was inspired by the success of the remake of Battlestar Galactica.
As well as the remakes of The Bionic Woman and Knight Rider, though those didn't do so well.
And Stargate Universe, the cancellation of many of these series has inevitably led to the death of the Science Fiction Genre on TV.
Desperate Housewives also inspired a series of reality series about actual housewives and their social circles called Real Housewives (of Orange County, Atlanta, etc.). Most of them run on the Rule of Drama.
Jerseylicious on Style is an obvious copy of Jersey Shore. In general there have been a lot of New Jersey-related reality shows since Jersey Shore became incredibly popular.
The Osbournes jump-started the "everyday lives of celebrities" series of reality shows albeit mostly with B- to C-list tabloid fodder. It was followed by Keeping Up with the Kardashians, Living Lohan, etc.
It isn't. There have been whispers of a "reality show curse," and it isn't entirely unfounded. Almost every celebrity couple who has done a domestic reality show a la The Osbournes or Newlyweds has split up (only the original Ozzy and Sharon are still together.)
Pawn Stars has inspired a host of imitators related to antiques and valuable artifacts:
Other pawn shop shows, such as TLC's Pawn Queens, which is essentially a Distaff Counterpart of Pawn Stars, and TruTV's Hardcore Pawn, focusing on Detroit pawnbroker/scumbag Les Gold and his sleazy family;
Duck Dynasty turned out to be a hit, resulting in a slew of "Rednecks doing things" shows, many of which missed the fact that the Duck Dynasty guys are extremely self-aware about redneck stereotypes and often poke fun at themselves rather than playing it completely straight.
Five years after its launch we saw Mad Men clones in the form of BBC 2's The Hournote As opposed to the CBC's The Hour, which is different, ABC's Pan Am (which could also be called Mad MenON A PLANE!), and NBC's The Playboy Club. Although those shows had the benefit of being released while their originator was on hiatus, only The Hour got a second season. (It did not get a third.)
The success of Weeds has led Showtime to do a number of very similar shows with the same base (acclaimed actress stars in show about normal person with a dilemma), such as Nurse Jackie (Weeds with prescription drugs), The Big C (Weeds with cancer) and United States of Tara (Weeds with multiple personality disorder). In fact, this seems to be most of their series output.
The Bachelor touched off a slew of dating shows. Then Joe Millionaire came along and tweaked the formula, so in addition to the progenitor, we have about a million versions with a slight twist (he's not rich, he's average-looking, he's a geek, et cetera).
Colombian telenovelaSin tetas no hay paraíso (There Is No Paradise Without Breasts) started the trend, apart from a remake with a bigger budget and a movie, of Darker and Edgier soaps in Latin Amerca (such as El Capo, El Cartel de los Sapos). These usually have a smaller duration, and are focused on drug lords, prostitution, corrupted politicians and being a soap disguised as a "serious drama".
The huge success of Saved by the Bell led to NBC executives eventually ordering a line of copies, including California Dreams. It eventually killed cartoons on Saturday Mornings for the network.
After Hot in Cleveland became a runaway hit, TV Land has been attempting to have lightning strike twice, creating a string of three-camera sitcoms featuring classic sitcom and Film veterans. Retired at 35 (George Segal, Jessica Walter), Happily Divorced (Fran Drescher, Rita Moreno), The Exes (Kristen Johnson, Wayne Knight, Donald Faison). It's contributed to TV Land's Network Decay (instead of showing classic sitcoms, it shows new sitcoms with classic sitcom actors), but they've been well received for the most part, so no one's really complaining too much.
When it was announced that Showtime was considering a TV adaptation of Chew, some thought it was inspired by hit Showtime series Dexter. Both Dexter and Tony Chu work in law enforcement and have disgusting side-activities that help them fight crime. But that's about as far as the similarities go.
Dexter may have also paved the way for United States of Tara and Nurse Jackie. Both are dark dramedy shows concerning a person struggling with a mental problem, split personality disorder in the former and drug addiction in the latter.
Dexter may have inspired BBC's Luther, which is about a psychotic killer who partners with a cop to fight crime. Luther, in turn, may have inspired NBC's upcoming Hannibal, which is about psychiatrist/serial killer Hannibal Lecter partnering with an FBI agent to solve murders.
This happens a great deal with Singaporean television, especially the childrens' programming. My Classmate Dad is a Body SwapSitcom that is Freaky Friday with a lower standard of spoken English. Cosmo and George is about an alien who befriends a human who shows him the ropes of living on earth, which is a startlinglyoriginal concept. Maggi & Me, about the relationship between a medium and an attractive female ghost, is very I Dream of Jeannie-esque. The Chinese-language drama serials are almost as bad in this respect. CID is CSI, The Time Machine is uh..., Baby Blues is uh..., Beach. Ball. Babes. is Dead or Alive (specifically volleyball tournament game, that is), and Mrs P.I., is Scarecrow and Mrs. King. The best part is that even if the shows are tenuously original, the English translations of their names, as you can gather, ruin everything.
Not only was ABC's Wide World of Sports one of American television's longest of Long-Runners, it inspired a raft of imitators both domestic (CBS's Sports Spectacular, NBC's Sportsworld, even ESPN itself) and international as well as several spinoffs (The American Sportsman, The Superstars, the Pro Bowlers Tour).
TLC does this to its own shows. After the success of Little People, Big World, they released more shows and specials about little people, such as The Little Couple and Little Chocolatiers. Similarly, after the success of Jon And Kate Plus Eight, they released more shows about large families, such as Table For 12 and 19 Kids and Counting.
TruTV is almost making Follow the Leader its hat. When it is not following the leader on its own shows (Lizard Lick Towing/Southern Fried Stings = Operation Repo) it is following them on other channels, such as the Discovery Channel or the History Channel. (Hardcore Pawn = Pawn Stars, Storage Hunters = Storage Wars, Police POV = C.O.P.S., Combat Pawn = Sons Of Guns / American Guns). They all have one common thread between them; several of them completely remove the educational aspects of the original shows (if there was one) in favor of pure over-the-top drama, which many suspect is scripted.
Worlds Wildest Police Chases inspired a whole slew of television shows about crazy events caught on police cameras. This eventually broadened into a whole genre of "crazy things caught on tape". Destroyed in Seconds, What Went Wrong, Most Shocking, Most Daring etc. Popular subjects include the North Hollywood Shootout and the San Diego Tank Chase. One of the few shows to take the formula and give it a twist is World's Dumbest..., which adds celebrity commentary and views things from a comedic perspective.
Quite a few people have drawn comparisons between The Hunger Games and NBC's Revolution. The former's lead character is a teenage girl with a bow. The latter's lead is a teenage girl with a crossbow. As a sci-fi show based on an overarching mystery, Revolution also joins the ranks of Lost imitators like FlashForward (2009), The Event, and Terra Nova.
After Price aired a trial week of sixty-minute episodes in September 1975, NBC expanded Wheel of Fortune and The Hollywood Squares from thirty minutes to a full hour two months later. Both reverted back to thirty minutes after a week with The Hollywood Squares doing so for good. Wheel planned on permanently expanding to a full hour after Price successfully did so but went back to its half-hour version after six weeks.
In 1992, Family Feud also attempted an hour-long format on both its versions. While the network version ended after fifteen months with the last six in repeats, the syndicated version lasted three years before it too was cancelled. When Feud returned to syndication in 1999, so did the half-hour format.
A revival of Let's Make a Deal, which has been airing since 2009, has used an expanded hour-long version without a hitch.
The Dinosaurs episode "Dirty Dancing" has an in-universe example where the TV line-up consists of nothing but shows involving idiot fathers, following the success of the show "Totally Ineffectual Dad". It also includes a Take That! to critics who accused Dinosaurs of being a The Simpsons knock-off:
Earl: "This is why TV stinks. One show's a hit, they make 50 more just like it, with the same characters and the same premise."
Baby: "Don't have a cow, man!"
Dallas spawned a whole raft of nighttime soaps, with its own spinoff Knots Landing and Dynasty being the most successful. Then there was Flamingo Road, Secrets of Midland Heights, Berrenger's, Kings Crossing...
In the 1980s, British television Granada began a series of incredibly faithful adaptations of the Sherlock Holmes stories, starring Jeremy Brett as Holmes. After its success, it was eventually followed by a series of incredibly faithful adaptations of Agatha Christie's Hercule Poirot stories, starring David Suchet as Poirot. This particular case is arguably a Tropes Are Not Bad example, since both series and their stars are largely acclaimed as being definitive adaptations.
After The NBC Mystery Movie became a hit, ABC tried its own Wheel Program concept with The Men (Robert Conrad in Assignment: Vienna, James Wainwright in Jigsaw and Lawrence Luckinbill in The Delphi Bureau) - it didn't last, and neither did any of the elements. Universal, the company behind the Mystery Movie strand (and Jigsaw), tried to replicate the success itself with Great Detectives, shooting three TV movies (The Hound of the Baskervilles with Stewart Granger as Sherlock Holmes, The Adventures Of Nick Carter starring Robert Conrad, and A Very Missing Person with Eve Arden as Hildegarde Withers) for a planned series. No go.
ER (which itself was probably following several other leaders) all but revived the gritty urban medical drama, spawning several poor imitators that didn't last very long. Even though it's been off the air for years, you can still see its influence in the medical dramas of today.
The top 3 rated dramas of the 2014-2015 season were Empire, How to Get Away with Murder, and Scandal, each of which star African-American leads, while Black-ish and Fresh Off the Boat proved to be surprise comedy hits (the former of which stars a black family and the latter of which stars an Asian-American family). This has led to the networks scrambling to find more racially diverse programming, with ABC ordering a new show starring Ken Jeong and HBO launching a writing fellowship to find more diverse creators.
In Japan during the 70s, the Ultra Series was at the height of its popularity and television ownership was increasing across the nation. Not surprisingly, many studios decided to cash in on the Henshin Hero genre resulting in many other shows and superheroes like Spectreman, Zone Fighter, and Megaloman. Even Godzilla got into the trend with Godzilla vs. Megalon's robot hero Jet Jaguar. Funny enough, a couple of the imitators were from Ultraman's creators like Fireman, Mirrorman, and Jumborg Ace.
The OWN series Greenleaf has been called Empire in a megachurch.
In 2005 Animal Planet began the Puppy Bowl, a puppy-based show on Superbowl Sunday. In 2002 it added a kitten half-time show. Hallmark Channel however has an entire Kitten Bowl dedicated to kittens, which began in 2014. National Geographic Channel's nature-based spinoff channel, Nat Geo Wild, began the Fish Bowl in 2015, which is nothing but fish swimming in a bowl.
