->''"The name of [[Literature/{{Warbreaker}} this world]] is Nalthis, by the way. Franchise/{{Mistborn}} takes place on a world called Scadrial, and Literature/{{Elantris}} on a world known as Sel. See the fun things you learn by reading annotations?"''

Information not mentioned within the show and only found in other material related to the franchise. The difference between this and normal merchandising is that this information may be relevant to understanding the plot and thus making the audience wonder why the writers didn't put it ''in'' the show to begin with.

For example, many anime [[OriginalVideoAnimation OVAs]] based on a manga begin with a OneWePreparedEarlier situation and rarely explain themselves under the assumption an OVA (being an occasional test run for a series) will typically be watched by someone who has read the original manga.

Other information can be found in text novels, video games, [[AudioAdaptation radio dramas]], and {{image song}}s, as the entire franchise is treated as a package. Though if you don't have the money for all that, your best bet is [[ThatOtherWiki Wikipedia]]. When done to extremes, CrackIsCheaper.

Fairly common in {{anime}} and mostly unknown in American shows, although it seems to be steadily picking up speed with shows like ''Series/{{Lost}}''. However, it's very common in American comic books because of the assurance the stereotypical fan is obsessive enough to collect supplemental material (see UltimateUniverse). This also applies to the elaborate backstories many video games of the 1980s provided in accompanying comic books or novellas.

If this material is necessary to progress in a video game or work on fanfiction, it becomes a GuideDangIt. If the manual contains information that the player isn't supposed to know until some playing, it's SpoiledByTheManual. AllThereInTheScript is a subtrope of this, referring specifically to names. When it's all there in an InUniverse book, see GreatBigBookOfEverything.

Compare DeletedScene. Not to be confused with ReadTheFreakingManual, which refers to the oversight of not reading the manual despite it containing practical information.
