The last use is definitely the most popular use of television today. Television as theater usually refers to the transmission of dramatic presentations either made especially for the medium or originally made to be exhibited in [[motion picture]] exhibition halls ("movie theaters") but now offered for instantaneous mass transmission. Television ''also'' is the modern means of allowing millions of people to view public games. Though the original public games of, say, the [[Rome|Roman Empire]] are no longer being staged, their spiritual descendants continue as, for example, [[automobile]] racing and various contact and non-contact [[sport]]s. Virtually any spectacle that in earlier centuries would draw large numbers of attendees is a candidate for transmission on television. This especially includes the installation of a new head-of-state.
