Gateway, Inc., previously Gateway 2000, Inc., was an American computer company originally based in Iowa and South Dakota. Founded by Ted Waitt and Mike Hammond in 1985, the company developed, manufactured, supported, and marketed a wide range of personal computers, computer monitors, servers, and computer accessories. At its peak in the year 2000, the company employed nearly 25,000 worldwide. Following a seven-year-long slump, punctuated by the acquisition of rival computer manufacturer eMachines in 2004 and massive consolidation of the company's various divisions in an attempt to curb losses and regain market share, Gateway was acquired by Taiwanese hardware and electronics corporation Acer, in October 2007 for US$710 million.
