For wealthy Britishers, there had been an annual ‘London Season.’ Several cultural events, as the opera, the theatre, the classical musical performances were organised for an elite group of 300-400 families. Many new types of large-scale entertainment for the common people came up. Libraries, art galleries and museums were established to provide entertainment to people who swarmed them. Music halls were popular among lower classes, and by the 20th century, cinema became the great mass enertainer for mixed audiences. British industrial workers were encouraged to spend their holidays by the sea. Over a million Britishes went to the seaside in 1883; their number increased to 7 million in 1939.
