The development of cantilevered balconies was another innovation. These did not need supporting columns that impeded the audience’s view of the stage. Concrete soon became a popular material for theatre construction, not only for its resistance to fire, but also because it could be moulded into elaborate curved forms. The period from the 1880s to World War I was the greatest era of theatre building. The development in the early 20th century of stage machinery that was powered by water enabled more spectacular productions to be presented, and shows with increasingly ambitious special effects were devised to attract and retain audiences. The period also saw the arrival of a new component in variety shows that would eventually lead to the closure of hundreds of theatres. This was the bioscope*, an innovation so popular that new or refurbished theatres often included provision for screening silent films.
