Dallas–Fort Worth metroplex
Dallas and its suburbs have one of the highest concentrations of corporate headquarters in the United States. Business management and operations is a major part of the economy. The metroplex also contains the largest Information Technology industry base in the state (often referred to as Silicon Prairie or the Telecom Corridor, especially when referring to US-75 through Richardson just north of Dallas itself). This area has a large number of corporate IT projects and the presence of numerous electronics, computing and telecommunication firms such as Microsoft, Texas Instruments, HP Enterprise Services, Dell Services, Nokia, Cisco, Fujitsu, i2, AT&T, Alcatel-Lucent, Ericsson, CA, Google, 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, primarily on the "Fort Worth side." They are concentrated along State Highway 170 near I-35W, commonly called the "Alliance Corridor" due to its proximity to the Fort Worth Alliance regional airport. ExxonMobil, the #2 corporation on the Fortune 500 listings, is headquartered in Irving, Texas. Toyota USA, in 2016, relocated its corporate headquarters to Plano, Texas. Southwest Airlines hold their headquarters in Dallas. The airline has more than 53,000 employees as of October 2016 and operates more than 3,900 departures a day during peak travel season.
