[custom_adv] A television show (often simply TV show) is any content produced for broadcast via over-the-air, satellite, cable, or internet and typically viewed on a television set, excluding breaking news, advertisements, or trailers that are typically placed between shows. [custom_adv] Television shows are most often scheduled well ahead of time and appear on electronic guides or other TV listings. A television show might also be called a television program (British English: programme), especially if it lacks a narrative structure. [custom_adv] A television series is usually released in episodes that follow a narrative, and are usually divided into seasons (US and Canada) or series (UK) – yearly or semiannual sets of new episodes. A show with a limited number of episodes may be called a miniseries, serial, or limited series. A one-time show may be called a "special". [custom_adv] A television film ("made-for-TV movie" or "television movie") is a film that is initially broadcast on television rather than released in theaters or direct-to-video. [custom_adv] Television shows can be viewed as they are broadcast in real time (live), be recorded on home video or a digital video recorder for later viewing, or be viewed on demand via a set-top box or streamed over the internet. [custom_adv] The first television shows were experimental, sporadic broadcasts viewable only within a very short range from the broadcast tower starting in the 1930s. [custom_adv] Televised events such as the 1936 Summer Olympics in Germany, the 1937 coronation of King George VI in the UK, and David Sarnoff's famous introduction at the 1939 New York World's Fair in the US spurred a growth in the medium, but World War II put a halt to development until after the war.
