Film and cinema have developed significantly since the late 19th century. The kinetoscope, invented in 1891, was the first device to display moving images but could only be viewed by one person at a time. In 1894, the phantoscope was invented, allowing for the first public projections of films. The Lumiere brothers' 1895 cinématographe was a more portable projector that helped popularize moving pictures. By the early 1900s, narrative films like The Great Train Robbery emerged, and sound was introduced to films with The Jazz Singer in 1927. Major developments in the 1970s included the rise of the blockbuster film and higher budgets, exemplified by the highest-grossing film of all time, Avatar
