A collection of distinct series which are often considered as a collective unit under a blanket title. They often, but not always, share a common continuity; even when they do not, they are more closely bound than spinoffs.
While characters may come and go, formats may change from live action to animated and back again, and even production houses/creators may change over time, the thing that remains constant for a franchise is the universe in which it takes place.
In the US, series franchises are fairly rare, and usually result from a series spawning several successful Revivals, though in recent years, an increasing number of successful US series have spawned concurrent franchises, where more than one installment has aired simultaneously.
Franchises are more common in other countries, especially in the Anime and Toku genres of Japan. However, they are frequently implemented by way of Alternate Continuities that employ the same core cast in slightly (or greatly!) different settings, rather than alternate casts in the same continuity. This version is also very common in video games.
Reality shows are also often counted as franchises, with each season being counted as a distinct series in its own right (Thus Survivor is considered a Franchise, whose installments include Survivor: Palau, Survivor: All-Stars, etc.).
Concurrent U.S. franchises
Consecutive U.S. franchises
- Star Trek (5 series [some of which ran concurrently], 11 movies, an Animated Adaptation and a great many video games for pretty much every platform, plus a bazillion tie-in novels)
- Saved by the Bell (3 series, or 4, depending on how Good Morning Miss Bliss is counted)
- Transformers (The main continuity family includes three American cartoons and five Anime series, each of which has at least one accompanying comic and a Manga. There's also another several mangas and a couple of other comics which without corresponding cartoons. Breaking off into alternate universes there's the Japanese-made Robots in Disguise, consisting of a cartoon and manga, and the Unicron Trilogy, which comprises three anime series, each of which has a corresponding comic. More recently, there's been an American live-action movie and a new cartoon, and guess what? Each of those has a comic as well. Oh, and if we tried to list all the tie-in books, toys, clothing, etc? We'd break the internet. And we still can't get enough.)
- G.I. Joe (an uncommonly large number of action figures, 4 different animated series, a live-action film, and comic books and video games)
- Power Rangers by way of Super Sentai below. (18 seasons (officially 19, but one's just a rehash of the first), or 15 series, depending on how you choose to count it.)
- Gundam (Eleven series, plus OAV releases, movies, in-canon games and even a ride, some in the same continuity, some not)
- Super Sentai (35 series since 1975)

- Yu-Gi-Oh! (a long-running card game, four anime series, and countless video games, as well as several manga series, one of which being where the series started from.)
- .hack (3 anime series, 7 games with a tie-in OAV each, plus manga and light novels) and growing! It now includes a movie (sadly non-canon) more manga and games, a few ova, a 4Koma series.
- Pokémon: Five distinct series (original: 1997-2002; Advanced Generation: 2002-2006; Weekly Pokémon Broadcast's sidestory episodes (US: Pokémon Chronicles): 2002-2004; Diamond & Pearl: 2006-2010; Best Wishes: 2010-present) and 13+ annual movies. The anime franchise is just about as big, if not bigger, than the actual video game franchise; see below.

- Toei produced all of the early Magical Girl shows, starting with Sally the Witch in 1966, meaning that "Magical Girl" was more of a Series Franchise than a genre. This lasted until Ashi Productions' Magical Princess Minky Momo hit the airwaves in 1982.
Video Game franchises

- Pokémon (Five generations of games, plus spinoffs for each in genres like puzzles and pet sims. Then there's
aseveral manga, the anime (which, as previously listed, is almost a franchise in itself), and the Trading Card Game. Probably the most successful translation of a video game to other media, which has led to Adaptation Displacement among some people.)
- Bomberman (20+ games and still running since the mid-1980s)
- Castlevania (15+ games since 1987)
- Fire Emblem (12 games across different Nintendo platforms with a 13th upcoming, also incorporates several manga adaptations, an OVA adaptation, and a card game)

- When They Cry (four main games under two separate titles [[[Higurashi]], Higurashi Kai, Umineko no Naku Koro ni, Umineko Chiru], two fandiscs, two spin-off fighting games and several console ports, as well as animated and manga adaptations for both series)
- Most of Frank Herbert's books and short stories (especially his non-Dune works) share many common historical aspects, despite being set across vast expanses of spacetime.
- Larry Niven's Known Space, which includes the Ringworld series of novels, the Man-Kzin Wars series, and even a Star Trek: The Animated Series episode (which is why TAS isn't in continuity with the live-action Star Trek series.)
- The Hitchhiker's Guide to the Galaxy: Five seasons on radio and one on television, five books (six if you count And Another Thing), two short stories, a computer game, three theatrical performances (including one musical), two singles, a feature film, three comic books, two records, and two bath towels—all in their own continuities mutated off the first two radio series and last three books—the result is that, for all that mess, it covers somewhere around six installments of one story.
- .hack is just plain ridiculous about this:
- The first wave, Project .hack, originally consisted of the .hack//Sign anime, the Infection, Mutation, Outbreak and Quarantine games (which were each bundled with an episode of the OVA series .hack//Liminality), and the .hack Legend of the Twilight manga. Other canon included the .hack//AI buster light novels. Then there were two manga adaptations of the games, XXXX and Another Birth (from BlackRose's point of view), neither of which are canon.
- The second wave consisted mainly of the second anime, .hack//Roots, and the .hack GU Games (Rebirth, Reminisce and Redemption). There was also a CGI movie adaptation, a manga adaptaion and a light novel adaptation of the games, all of which were done differently.
- The third, and probably final, wave consists of the anime .hack//Quantum and .hack//LINK, which could refer to a manga or a PSP game that (as far as I can tell) follow the same story. There's also a movie in the works.
- 7 series from 1971-1981 and 2 series in 1987-1989 (all of which take place in the same universe), then 1 Direct to Video film in 1992 and 2 theatrical features in 1993-1994 (which occupy their own little continuities).
- one TV series per year from 2000-present, each of which has at least one movie, all seperated by The Multiverse as mapped out by Kamen Rider Decade.
