1935 was characterized by three major changes to the Chicago Auto Show: The Chicago Automobile Trade Association (CATA), the United States' oldest and largest metropolitan automobile dealership organization, became the event's producer and organizer. Also, the show was held twice in calendar year 1935—once in January for the 1935 models, and once in November for the 1936 models. This arrangement was a result of automakers shifting the start of the model year to the fall, based on a recommendation by President Franklin Delano Roosevelt to advance the introduction of new automobile models by two months. Finally, the November 1935 show moved to a much larger venue, the International Amphitheatre located at 4220 South Halsted Street.
