A timeline and “family tree” of the major American movie studios. Organized around the top 5 producers of feature films throughout the years. The “market share” percentages on the right edge of the graphic are sourced from The-Numbers.com 2020 Distributors Gross Earnings. The information is based on the “major film studios” chart on Wikipedia.
