Episode
An episode is a single portion of a greater body of related works, usually entertainment programs on television and radio. The term sometimes applies to works distributed through other forms of mass media, especially when such material is serial in nature with story lines that link together. The word episode is not frequently used to describe news programs, however.When radio and television programs are divided into episodes, most individual shows will have their own titles. These titles may not ever appear on screen or have their names read aloud, however—the titles are often just a reference for writers, actors, and others involved in production.
Each individual show also often has an episode number or episode code which can be difficult to parse, depending on the format used. Many programs use a three- or four-digit number, with the first one or two digits indicating the season (or series, for English speakers outside the U.S.) and the last two digits indicating the episode number within the season. For example, the fifth episode in season six might appear as number 605. Other programs may just number programs one after another, although things can become confusing later if episodes never finish production or are shown in a different order than they were produced. Some programs, such as The Simpsons, use numbering systems that are hard for anyone other than the original artists to understand.
The term episode can also be a generic term for a thing that has taken place, particularly if the event was embarrassing or involved a certain level of danger.
