context: The movie industry was born in Paris when Auguste and Louis Lumière projected the first motion picture for a paying audience at the Grand Café on 28 December 1895. Many of Paris' concert/dance halls were transformed into movie theatres when the media became popular beginning in the 1930s. Later, most of the largest cinemas were divided into multiple, smaller rooms. Paris' largest cinema room today is in Le Grand Rex theatre with 2,700 seats.
  Big multiplex movie theaters have been built since the 1990s. UGC Ciné Cité Les Halles with 27 screens, MK2 Bibliothèque with 20 screens and UGC Ciné Cité Bercy with 18 screens are among the largest.
