In 1940, the population of Phoenix was over 65,000, and the city was growing rapidly. As home air conditioning became more affordable following the war, the population grew substantially. In that period, hundreds of manufacturing firms relocated from other parts of the country.
Many of the men who had been trained in Arizona returned to their families after the war. Many large industries moved their operations to the area after learning of this large pool of untapped labor. The high-tech industry began to develop in Phoenix when Motorola chose Phoenix as the site for its new research and development center for military electronics in 1948. Like Motorola, other high-tech companies, such as Intel and McDonnell Douglas, moved into the valley and opened manufacturing operations.
