His company's influence was so vast that it controlled around 90% of the U.S. oil refineries and pipelines by the early 1880s. In 1911, Standard Oil was broken up by the U.S. Supreme Court due to antitrust violations, but Rockefeller's wealth continued to grow from the shares he held in the resulting companies.
