Mobil, previously known as the
Socony-Vacuum Oil Company, is a major United States oil company which merged with
Exxon in 1999 to form a parent company called
ExxonMobil. It was previously one of the
Seven Sisters that dominated the global petroleum industry from the mid-1940s to the 1970s. Today Mobil continues as a major brand name within the combined company, as well as still being a gas station sometimes paired with its own store or
On the Run. The former Mobil headquarters in
Fairfax County, Virginia, were used as ExxonMobil's downstream headquarters until 2015 when ExxonMobil consolidated employees into a new corporate campus in
Spring, Texas.
