↓ "The cities of Dallas and Fort Worth are the anchor cities of
the Metroplex. Dallas and its suburbs have one of the highest concentrations of corporate
headquarters in the United States. As such, one of the largest industries in the Metroplex is
conducting business. The Metroplex also contains the largest Information Technology industry
base in the state (often referred to as Silicon Prairie), owing to the large number of corporate
IT projects and the presence of numerous electronics, computing and telecom firms such as Texas
Instruments, Electronic Data Systems, Perot Systems, i2, AT&T, and Verizon in and around
Dallas. On the other end of the business spectrum, and on the other side of the Metroplex, the
Texas farming and ranching industry is based in Fort Worth. According to the Dallas Business
Journal's 2006 Book of Lists, American Airlines is the largest employer in the Metroplex.
Several major defense manufacturers, including Lockheed Martin, Bell Helicopter Textron, and
Raytheon, maintain significant operations in the Metroplex. ExxonMobil, the #1 corporation on
the Fortune 500 listings, is headquartered in Irving, Texas."
