On January 1, 1973 Exxon formally replaced the Esso, Enco and Humble brands of motor fuel and related products. From 1972 until 1999 Exxon was the corporate name of the company known as Standard Oil Company of New Jersey, or Jersey Standard.
Exxon announced its intention to move its headquarters from its location at 1251 Avenue of the Americas in Manhattan to Las Colinas near Irving, Texas. The old headquarters, the Exxon Building, was sold to a unit of Mitsui Real Estate Development Company Ltd for $610 million in 1986. According to John Walsh, president of Exxon subsidiary Friendswood Development Company said that Exxon and its 300 employees were relocation to Texas due to the high costs of having their headquarters in New York City.
