Purpose of short film-Self promotion

Short films are often created in order to promote directors or film makers (Self promotion) that are young, unheard of by making short films they have the chance to gain recognition and credit for their work. The directors and film makers would earn this recognition either by entering the film into contests or European film festivals and well known film festivals such as the BFI London Film Festival or British Independent Film Festival alongside promoting it on either Youtube or late at night on Channel 4 or distributed over the internet in a way. An example of a film director that got recognition of his $300 short film that went viral over youtube is Fede Alvarez with his short clip 'Panic Attack' within forty eight hours Alvarez had been acknowledged by Hollywood film companies who offered him the opportunity to create a mainstream, full length film with a budget of $30 million.
