History and Evolution of Film

I researched the evolution of film and sorted the information on this table; 

DATE 1880	EVENTS Multiple inventions(1880s)took place: As multiple inventors began working on various sorts of moving picture cameras or motion picture cameras. The first films were created by the end of the decade. That was a great accomplishment.
1890	First Public Displays(1890s),A step forward: The first public showings of films took place in the 1890s. The first theater was built in Philadelphia in 1899. Film companies began building film studios around 1900, as they saw profit in this immerging interest of people.
1903	The Great Train Robbery(FILM) In 1903, the Edison Corporation produced the first western film, and established the use of shots and editing in film. This also marks the growing popularity of story films, over daily life scenes or news. It was however a silent film
1910	Edison's Kinetophone Edison invented the Kinetophone, making talkies an option. They would not become popular for more than 20 years. However it was short film, a test for Edison's "Kinetophone" project, the first attempt in history to record sound and moving image in synchronization.
1927	The Jazz Singer Released in 1927, The Jazz Singer is the first feature-length talkie. The film starred Vaudeville sensation Al Jolson. It is the first feature length motion picture with both synchronized recorded music score as well as lip-synchronous singing and speech (in several isolated sequences).
1935	Technicolor With the release of Becky Sharp, audiences could now see films in technicolor, a series of processes used to first produce color in motion pictures. Two-color film technology had been available, but rarely used since 1922.
1948	McCarthyism Hollywood was threatened by McCarthyism, it was a vociferous campaign against alleged communists in the US government and other institutions The Hollywood Ten refused to divulge any communist leanings and were imprisoned for contempt of court.
1953	Wide Screen With the invention of television, film needed to up its game. New widescreen processes to produce bigger and more exciting films were the answer.
1953	First 3-D Film The first 3-D film, relying upon stereoscopic technology, achieved wide release in 1953. Earlier attempts had been made but not all were successful, but the 1950s saw the popularity of 3-d.
1968	Motion Picture Ratings The Motion Picture Association film rating system is used in the United States and its territories to rate a motion picture 's suitability for certain audiences based on its content. Motion picture ratings were introduced in 1968, with G, PG, R and X. PG-13 came significantly later.
1976	Introduction of the Steadycam The Steadycam, first used in Rocky, became available offering new options to filmmakers. This ensures shot's stability.
2003	Home Entertainment Revenues Exceeded Box Office In 2003, for the first time, home entertainment revenues exceeded the box office. The DVD took over for the video cassette in 2003 as well. This was a new profitable evolution.
2003	Growth of 3D films(2003 Onward) With improving technology, 3D films became more popular. In addition, a number of new IMAX facilities, offering larger format screens were constructed. Today, many large-budget films can be watched in 2D or 3D,based on your choice.
