Marathon began as The Ohio Oil Company in 1887. In 1889, it was purchased by John D. Rockefeller's Standard Oil trust. It remained a part of Standard Oil until the trust was broken in 1911. In 1930, The Ohio bought the Transcontinental Oil Company, giving it the "Marathon" brand name. In 1962, the company changed its name to "Marathon Oil Company" after its main brand name. Mobil wanted to buy the company in 1981. The residents of Findlay, Ohio, the corporation's home town, worried that the Findlay jobs would be lost so Marathon looked for a white knight. They found one in 1982 when United States Steel bought the company.
 
The headquarters moved to Houston in 1990 but the company maintained downstream operations in Findlay (which are now Marathon Petroleum). In 2001, USX, the holding company that owned United States Steel and Marathon, spun off the steel business and in 2002 USX renamed itself Marathon Oil Corporation.
In 1998, Marathon and Ashland, Inc., formed Marathon Ashland Petroleum LLC to refine, market and transport crude oil and petroleum products, primarily in the Midwest, the upper Great Plains and southeastern United States. In 2003, Marathon sold off its Canadian operations to Calgary-based Husky Energy
 
Marathon recently divided its two main businesses: 1) The “upstream” business, which is responsible for the exploration and mining of oil and 2) The “downstream” business, which is about the refining, marketing, and transportation of the oil. In broad terms the upstream business has been spun-off into its own company called Marathon Petroleum Corporation and is keeping the old logo. The downstream business has kept the Marathon Oil Company name and adopted a new logo.
