Three Shorts

A popular format in which to present a cartoon show. The half hour, 22 minutes of program time, is used to show three six-minute short cartoons. The remaining time is used for short framing segments or one-minute gags.

Many shows follow an A-B-A form for this format, meaning one series has a short in the first slot and in the last. This "A" series is generally the one that gives the whole show its name. The middle slot is filled by a second "B" series, that may or may not get billing in the Title Sequence. The "B" series is often in the same universe as the "A" series, and the two can often Crossover, with the virtue that everyone who has seen the one will almost inevitably see the other. Hanna-Barbera likes this format for its Cartoon Network original shows, and many of its older productions.

This form has some advantages. The short episodes are easier to produce in parallel, since writing and animation tasks can be farmed out to a bigger staff, resulting in higher productivity. This, and carrying a comedic story for 22 minutes can be tricky. A six-minute short doesn't give the premise of a joke enough time to run out of steam.

This is different from an Animated Anthology, in that a specific two or three series are used, and both are made new for this format. Animated Anthologies have widely variable structures within a given episode, while Three Shorts shows are usually locked into the exact form.

Most series today use a Two Shorts form, with a pair of eleven-minute episodes. Originally very rare, it's practically the standard for comedy. Some half-hour animated shows have a few Two Shorts episodes made up, any half of which can be used as emergency schedule filler around odd-length specials or movies. (The Disney Channel likes these, there are three episodes of Kim Possible that follow Two Shorts form, and they crop up after any given movie airing.)

Sometimes, in between the shorts are super-short one-joke bits. Garfield and Friends called these "Quickies", and they were often adapted from a single Sunday strip.

Anime and Manga

 * Some Anime air (in Japan) in a form like this, notably Risky☆Safety and Oruchuban Ebichu, although the series they aired with are less notable. More common are the half-length episodes (about 13 minutes) which air back to back in a half-hour timeslot. Final Approach and W Wish aired together in this manner.
 * The anime version of Keroro Gunsou usually followed a Two Shorts format.
 * Urusei Yatsura began as a Two Shorts format, sometimes leading to confusion about how many episodes there are since the shows from this period may be counted as either one or two.
 * Azumanga Daioh was broadcast as one five-minute episode per weekday, which were then stitched together into a half-hour Five Shorts form on Saturday.
 * Episodes two and onward of (Zoku) Sayonara, Zetsubou-sensei follow this format.

 * Animaniacs, ABA with a rotating cast of B's, most notably Pinky and The Brain.
 * About a third of the episodes of the spinoff version of Pinky and The Brain used the Two Shorts format, occasionally with a quickie musical filler.
