Context paragraphs:
Chicago film industry: The Chicago film industry is a central hub for motion picture production and exhibition that was established before Hollywood became the undisputed capital of film making.  In the early 1900s, Chicago boasted the greatest number of production companies and filmmakers.  Essanay Studios founded by George K. Spoor was one of the earliest successful studios to produce movies in Chicago, employing stars such as Charlie Chaplin and Gloria Swanson.  Actor and co-founder of Essanay Studios "Broncho Billie" Anderson gave birth to the western genre.  Early film companies such as Essanay Studios produced multiple silent films every week and rented viewing equipment to showcase the latest cinematography to the public.  This rental culture gave birth to the popularity of Nickelodeons up until the Great Depression.  However, due to the high demand for motion pictures during this time, a black market for films and equipment developed.  The Motion Picture Patents Company, established in 1909 as a conglomerate of the major studios, sought to eliminate all illegal use of patented film equipment.  As a result, independent ventures entered the film scene.  Independents drove the film industry to the west to avoid legal trouble with the trust of major film companies united under the Motion Picture Patents Company.  The west offered fairer weather and scenery that better accommodated film making.  Not until the 1980s and early 21st century has Chicago experienced a film production revival.  Blockbusters, such as "Blues Brothers", "Sixteen Candles", and "The Dark Knight", have rejuvenated the Chicago film scene.  In the 21st century, Chicago further experienced a film revival due to a tax bill the state of Illinois passed to give filmmakers a 30% tax break on production costs.

This was the time when there was no clear idea about how to define a film festival.  At that time, SEOUL International Women’s Film Festival came up with a catchphrase See the world through women’s eyes, setting its main goal to introduce women’s films that explore the “women’s reality from the women’s perspectives”.  Featuring films by women, for women, and of women, the 1st edition of SEOUL International Film Festival received a number of positive reviews from the audience, which was never anticipated this much.  Thanks to continuous support from the audience, SEOUL International Film Festival that used to be happening every other year has become an annual event since the 3rd edition in 2001.  For the 6th edition in 2004, SEOUL International Women’s Film Festival looked for changes by relocating the festival office and venues to Sinchon, the street of youth and culture.  For the 9th edition in 2007, the Queer Rainbow section was first introduced, presenting films about life and culture of gender minorities.  In order to go beyond the gender boundaries based on biological sex and to reach out for solidarity, SEOUL International Women’s Film Festival newly created the Open Cinema section encompassing feminist films made by male directors.  Now in 2015, SEOUL International Film Festival attempts to build its new festival identity and become a cultural platform more approachable for a wide variety of audiences by changing the official English title of the festival from International Women’s Film Festival in Seoul to SEOUL International Women’s Film Festival as well as by retouching the festival logo used for last 17 years.
