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. A group of these combined via a Crossover series is a Modular Franchise.
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: Borneo, Survivor: The Australian Outback, et cetera.)
On TV Tropes, multimedia franchises may receive pages in the dedicated Franchise/ namespace if they exist in over three different forms of media, and they already have pages in each. They are indexed on the Franchise Index.
Examples of concurrent Live-Action UK franchises:
- Doctor Who during its 21st-century revival (the Davies era had the main show, the Darker and Edgier Torchwood, and the Lighter and Softer The Sarah Jane Adventures, all broadcast during the same period; the Moffat era spawned the Young Adult spin-off. Class). There has also been the huge Doctor Who Expanded Universe in other media, from the 1960s to date.
Examples of concurrent Live-Action US franchises:

- G.I. Joe (An uncommonly large number of action figures, 4 different animated series, live-action films, and comic books and video games.)
- Power Rangers by way of Super Sentai below. (Has had consecutive installments for 20 years, but exactly how many installments that IS has gotten complicated.

- Saved by the Bell (3 series, or 4, depending on how Good Morning Miss Bliss is counted.)
- Star Trek (5 series [some of which ran concurrently], 12 movies, an Animated Adaptation and a great many video games for pretty much every platform, plus a bazillion tie-in novels and comic books.)

Then there are several manga, the anime (which, as previously listed, is almost a franchise in itself), and the Trading Card Game.

Examples of cross-media franchises:
- .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 Dot Hack GU (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.
- Fate Series: 6+ mainline games, 6+ novels, multiple manga, over 20 anime adaptations (including serial movies and OVAs), multiple spinoffs (three of which became sub-franchises of their own), and counting.
- 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.
- Lupin III was much more successful than initially expected, to the point that some of the titles have been retroactively renamed to differentiate between them. It began as a Manga, but is much better known as an anime, even in Japan. The Lupin-verse is held in place through a combination of Broad Strokes, Negative Continuity, and Mythology Gag.
- My Friend Irma was once a very famous American franchise centered around a Dumb Blonde character named Irma Peterson (played by Marie Wilson.) Aside from the original radio series (which ran 1947 to 1953) it was also a television series (1952 to 1954), two feature films (My Friend Irma in 1949 and My Friend Irma Goes West in 1950) and a comic strip published by Marvel Comics writted and drawn by Stan Lee and Dan DeCarlo (1950 to 1955).
- 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 series, three new cartoons and a video game series, and guess what? Each of those have 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.)
