Brief history of Short films

Short films began in the 1910's in the USA. It was then common for a film to consist of one long feature film and a few short subjects afterwards. These were usually comedy. These short films were very popular until the 1930's when interest and demand declined. In the early 1950's television was introduced and brought about the fall of short films due to it broadcasting old short films, and a variety of new media. Thus, by the end of the 60's short films were dissapearing.
In the 1980's the term 'short film' was used interchangeably with 'short subject' which was this type of films original name.
Now, short films are popular again, diverse in themes. Some deal with the same themes as feature length films, but most tend to be more abstract, dealing with surreal film and with artistic value.
