The WatchEpisodes guide

The WatchEpisodes guide: the long runners of television

The long runners

WatchEpisodes is an English guide to 156 long runners of television, series that ran for a hundred episodes or more by the count that TMDB records. A long runner is a promise kept for years: the same family on the same couch every week, the same detectives in the same squad room, the same pirate crew sailing on season after season, so that viewers grow up with them and come back to them for the rest of their lives. The series sit on twelve shelves of thirteen, grouped in three families: comedy and animation; crime, medicine and other worlds; and drama across the decades. Every series has an English synopsis, the creators, the cast, the network, the list of its episodes and a Watch now button that opens it on JustWatch, which shows where it can be watched in your country.

Together the 156 series hold 1,691 seasons and about 42,300 episodes, an average of about 270 each; watched one after another, day and night, they would fill more than a year and a half. They carry about 374,400 votes on TMDB, with an average rating of 7.75, and 61 of them are rated 8 or more. The most voted is The Walking Dead, of 2010, the survivors of a world of zombies over eleven seasons and 177 episodes, with about 18,300 votes; the best rated is One Piece, of 1999, the pirates of Monkey D. Luffy, with an 8.8 and about 1,180 episodes. The guide Start with WatchEpisodes gives a first route through the shelves.

The oldest series of the guide, I Love Lucy, began in October 1951, when most American homes had only just bought their first television; the newest, from Riverdale and Young Sheldon to Black Clover, began in 2017. Between them, thirty series of the guide are still returning today with new episodes, from The Simpsons to Grey's Anatomy and One Piece. The guide Why series run long explains how a series reaches its hundredth episode.

The name and the look

The name WatchEpisodes says what a long runner is made of: episodes, hundreds of them, one after another. The Wayback Machine holds watchepisodes.tv and watchepisodes.com in October and November 2015 as a dark site of TV series, with a box of the trending series of the week, before the domains expired and were parked; the home page of 22 November 2015 and its stylesheet were read and measured. Only the look was measured; every picture and file of this site is new.

From that capture come the dark grey page, #181818; the near-black header, #090909, seventy pixels high, with a darker box for the logo and large links in a light weight, the current one in crimson, #E1184F; the boxes of a slightly lighter grey, #1B1B1B, with a thin border and a light title, and above all the box Trending Series, a ranked list of rounded rows, each with a crimson numbered circle, the name in pale grey and a small green arrow for a series on the rise. Here those ranked rows become the board Browse Series, with the twelve shelves numbered from 1 to 12 and the number of series of each shelf beside a green arrow. The guide The look of WatchEpisodes explains each colour.

How the long runners work

The series of the guide were chosen by hand from TMDB, among the series with a hundred episodes or more by the count of TMDB, or just under it for a few British series whose seasons are short, like Red Dwarf, Doc Martin and Dad's Army, which ran for many years with few episodes a year. Each series sits on a single shelf, and each shelf holds the thirteen most voted series of its kind with an English synopsis. The daily soap operas, which run to many thousands of episodes, were left aside, as were talk shows, reality shows and the news, so that the guide gathers the series that tell stories.

The twelve shelves are animation for adults, cartoons for children, classic sitcoms and the sitcoms of the new century for the first family; crime procedurals, medical dramas, science fiction and fantasy, and the anime long runners for the second; and the classics of the 1950s to 1970s, the teen dramas, the family dramas and the British long runners for the third. The three families each hold 52 series. The guide How the long runners work sums up the rules.

Why series run long

In American television a hundred episodes was long the magic number. A series that reached it, usually after four or five seasons, could be sold in syndication to local stations, which showed it every weekday, and the reruns paid for years of production; that is why so many series of the guide end between 100 and 300 episodes, and why the networks fought to keep a series alive until it crossed the line. The sitcoms of the guide, from Cheers to Friends and The Big Bang Theory, made seasons of twenty to twenty-four episodes; the procedurals, from Law & Order to NCIS, could run for twenty seasons because each case is complete in one episode, and a new detective can always replace an old one.

Japan and Britain followed other rules. The great anime of the guide are adapted from manga published every week in magazines like Weekly Shōnen Jump, and the series run every week of the year for as long as the manga lasts, so that One Piece, Detective Conan and Pokémon passed a thousand episodes. The British long runners are of two kinds: the police and medical dramas of ITV and the BBC, like The Bill and Silent Witness, made in many short seasons, and the comedies like Last of the Summer Wine, which ran for 37 years with a few episodes a year. Animation, finally, runs longest of all because its characters keep the same age on screen: Bart Simpson has been ten years old since 1989. The collection 500 episodes or more gathers the thirteen longest series of the guide, longest first.

The collection 500 episodes or more gathers them, longest first.

Thirty series of the guide are still returning with new episodes, by the status that TMDB records, and some of them began before many of their viewers were born. The Simpsons, of 1989, has been renewed into its fourth decade; South Park, of 1997, and Family Guy, of 1999, are close behind; One Piece, of 1999, and Detective Conan, of 1996, still air every week in Japan. In drama, Grey's Anatomy, of 2005, Law & Order: Special Victims Unit, of 1999, and Criminal Minds, of 2005, have each run for close to twenty seasons or more, and Dick Wolf's Chicago series, Chicago P.D. and Chicago Med, are still going.

The returning series also include the British Silent Witness, Midsomer Murders and Death in Paradise, the Canadian Heartland and the Hallmark When Calls the Heart, and the cartoons of the children, from Peppa Pig to Teen Titans Go! and PAW Patrol. King of the Hill came back in 2025 after fifteen years away, and Phineas and Ferb after a decade. The collection Still returning gathers the thirty, most voted first.

The faces of the long runners

A long runner can give an actor a role for most of a career. Mariska Hargitay has played Olivia Benson in Law & Order: Special Victims Unit since 1999, more than a quarter of a century, the longest run of any actor in a role of American prime-time drama; Ellen Pompeo played Meredith Grey in Grey's Anatomy for nineteen seasons, and Mark Harmon led NCIS as Leroy Jethro Gibbs from 2003 to 2021. James Arness was the marshal Matt Dillon of Gunsmoke for all twenty seasons, Kelsey Grammer was Frasier Crane for twenty years across Cheers and Frasier, and Jared Padalecki and Jensen Ackles drove the Impala of Supernatural for fifteen seasons. Tom Selleck led the family of Blue Bloods for fourteen.

The voices of animation last longest of all. Dan Castellaneta has voiced Homer Simpson since the shorts of 1987, before the series began; Tom Kenny has voiced SpongeBob since 1999; Mayumi Tanaka has been the voice of Luffy in One Piece since its first episode, and Rica Matsumoto was the voice of Ash in Pokémon for twenty-five years. In Britain, the actors of Last of the Summer Wine grew old with their characters over 37 years, and Peter Sallis played Clegg from the first episode of 1973 to the last of 2010. The guide The stars lists the faces and voices of the guide.

Spin-offs and families of series

Many long runners of the guide gave birth to others, and some of the children ran as long as their parents. Frasier, of 1993, took the psychiatrist of Cheers to Seattle for eleven more seasons; The Jeffersons, of 1975, moved the neighbours of All in the Family to a deluxe apartment of Manhattan and ran for eleven seasons too; Law & Order: Special Victims Unit, of 1999, has now outlived the original Law & Order in seasons; NCIS: Los Angeles, of 2009, made 323 episodes after NCIS; CSI: Miami, of 2002, made 232 after the first CSI: Crime Scene Investigation, and Private Practice, of 2007, followed a surgeon of Grey's Anatomy to California.

The new century kept the habit. Young Sheldon, of 2017, told the childhood of the hero of The Big Bang Theory for seven seasons; Boruto: Naruto Next Generations, of 2017, followed the son of the hero of Naruto and Naruto Shippūden; Chicago P.D. and Chicago Med grew from Chicago Fire, the first of the Chicago series of Dick Wolf, and The Flash began as a character of Arrow before getting his own series. Even Futurama, from the creator of The Simpsons, and American Dad!, from the creator of Family Guy, are cousins rather than children. The guide Spin-offs follows these families of series.

The makers of the long runners

Dick Wolf is the creator who appears most often in the guide, with four series that together hold more than 1,600 episodes: the original Law & Order, of 1990, Law & Order: Special Victims Unit, of 1999, and the Chicago series of NBC, Chicago P.D., of 2014, and Chicago Med, of 2015. Chuck Lorre made three sitcoms of CBS, Two and a Half Men, The Big Bang Theory and Young Sheldon, more than 680 episodes in all; Greg Daniels made The Office, Parks and Recreation with Michael Schur, and King of the Hill with Mike Judge. David Shore links the two great doctors of the guide, House and The Good Doctor; Matt Groening links The Simpsons and Futurama, Seth MacFarlane Family Guy and American Dad!, Shonda Rhimes Grey's Anatomy and Private Practice, and Kevin Williamson Dawson's Creek and The Vampire Diaries. Greg Berlanti and Andrew Kreisberg made Arrow and The Flash, and Jeff Davis created both Criminal Minds and Teen Wolf. The guide The creators follows them.

The networks

CBS is the first network of 27 series of the guide, the network of the crime procedural, from NCIS and the CSI series to Criminal Minds and Blue Bloods, and of the sitcoms of Chuck Lorre and the classics of the 1950s and 1960s, from I Love Lucy to Gunsmoke. NBC follows with twenty, from Cheers and Friends to the series of Dick Wolf; FOX with eighteen, from The Simpsons and The X-Files to House; ABC with sixteen, from Bewitched to Grey's Anatomy and The Good Doctor. TV Tokyo, the home of the anime, and The WB, the network of the teen dramas of the 1990s, have eight each, BBC One seven and Nickelodeon six. The guide The networks lists them all.

The guide The figures gathers every number.

Where to begin

For a first marathon, take one long runner from each family: The Simpsons or Friends for comedy and animation, House or The X-Files for crime, medicine and other worlds, and The Twilight Zone or Doc Martin for drama across the decades. Then choose a habit for the year: One Piece for a voyage of more than a thousand episodes, Gunsmoke for twenty seasons of the West, Star Trek: The Next Generation for seven years in space, Supernatural for fifteen years on the road and Heartland for a family that is still riding. For a lighter year, the sitcoms run fastest: an episode of Cheers, Frasier or The Big Bang Theory lasts about twenty-two minutes, so that a whole series can be watched in a few months of evenings, while a single season of Criminal Minds or ER fills a month. Families with young children can share Arthur, Hey Arnold! or Phineas and Ferb, and anyone curious about the oldest television of the guide can start with I Love Lucy and The Andy Griffith Show, the comedies that the whole of America watched together in the 1950s and 1960s. The guide Start with WatchEpisodes gives a first route.
