In 2015, Apple chose Mesa for a large data center in the former GT Advanced Technologies plant. 
The history of Mesa dates back at least 2,000 years to the arrival of the Hohokam people. The Hohokam, whose name means "All Used Up" or "The Departed Ones", built the original canal system. The canals were the largest and most sophisticated in the prehistoric New World. Some were up to 90 feet (27 m) wide and 10 feet (3.0 m) deep at their head gates, extending for as far as 16 miles (26 km) across the desert. By A.D. 1100 water could be delivered to an area over 110,000 acres (450 km2), transforming the Sonoran Desert into an agricultural oasis. By A.D. 1450, the Hohokam had constructed hundreds of miles of canals many of which are still in use today.
After the disappearance of the Hohokam and before the arrival of the early settlers little is known, as explorers did not venture into this area. By the late 19th century near present-day Mesa, U.S. Army troops subdued the Apache opening the way for settlement.
Mormon pioneerDaniel Webster Jones, with Henry Clay Rogers as his right-hand man, led an expedition to found a Mormon settlement in Arizona. Leaving St. George, Utah in March 1877, Jones and others arrived at Lehi, an area within the northern edge of present-day Mesa. Jones had been asked by Mormon officials to direct a party of people in establishing a settlement in Arizona. This settlement was initially known as Jonesville and Fort Utah and did not receive the name of Lehi until 1883, when it was adopted on the suggestion of Brigham Young, Jr.
At the same time, another group dubbed the First Mesa Company arrived from Utah and Idaho. Their leaders were named Francis Martin Pomeroy, Charles Crismon, George Warren Sirrine and Charles I. Robson. Rather than accepting an invitation to settle at Jones' Lehi settlement, they moved to the top of the mesa that serves as the city's namesake. They dug irrigation canals, some of which were over the original Hohokam canals, and by April 1878, water was flowing through them. The Second Mesa Company arrived in 1879 and settled to the west of where the First Mesa Company settled in 1880, due to lack of available farmland. This settlement was called Stringtown.
On July 17, 1878, Mesa City was registered as a 1-square-mile (2.6 km2) townsite. The first school was built in 1879. In 1883, Mesa City was incorporated with a population of 300 people. Dr. A. J. Chandler, who would later go on to found the city of Chandler, worked on widening the Mesa Canal in 1895 to allow for enough flow to build a power plant. In 1917, the city of Mesa purchased the utility company. The revenues from the company provided enough for capital expenditures until the 1960s. During the Great Depression, WPA funds provided paved streets, a new hospital, a new town hall and a library.
With the opening of Falcon Field and Williams Field in the early 1940s, more military personnel began to move into the Mesa area. With the advent of air conditioning and the rise of tourism, population growth exploded in Mesa as well as the rest of the Phoenix area. Industry--especially early aerospace companies--grew in the 1950s and 1960s. As late as 1960, half of the residents of Mesa made a living with agriculture, but this has declined substantially as Mesa's suburban growth continued on track with the rest of the Phoenix metro area.
In 1990, the Census Bureau reported city's population as 10.9% Hispanic and 84.9% non-Hispanic white.
Due to Mesa's extremely long east to west travel distance, in excess of 18 miles (29 km) and large land area 133.13 square miles (344.8 km2), locations in Mesa are often referred to as residing within either East Mesa or West Mesa.
Commonly accepted boundaries
Mesa employs a grid system for street numbering that is different from that used in Phoenix and other portions of the metropolitan area. Center Street, running north to south, bisects Mesa into eastern and western halves and serves as the east and west numbering point of origin within Mesa. Streets west of Center St., such as W. University Drive or W. Main St. are considered to be in West Mesa, whereas streets east of Center St., such as E. University or E. Main St., are considered to be in East Mesa.
Mesa Drive, running north to south and bisecting Mesa into east and west sections, is located 0.5 miles (800 m) east of Center Street, and serves as the zip code boundary between the 85281, 85201, 85202, and 85210 zip codes of Western Mesa and the 85203, 85204, 85205, 85206, 85207, 85208, 85209, 85212, 85213, 85215, 85220, and 85242 zip codes of Eastern Mesa.
Country Club Drive
Country Club Drive, running north to south and bisecting Mesa into east and west sections, is located 0.5 miles (800 m) west of Center St, and serves as the jurisdictional boundary between Arizona's 5th and 6th congressional districts. Note that this same road (as Arizona Avenue) serves as the official east and west numbering point of origin within the city of Chandler, located south of Mesa.
