Gateway, Inc. is an American computer hardware company based in Irvine, California which develops, manufactures, supports and markets a wide range of personal computers, computer monitors, servers, and computer accessories.

In the early and mid-2000s, the company struggled; after years as a fixture on the Fortune 500 list of largest companies worldwide, the company was not listed in 2006, having dropped to number 508. Gateway became widely known in 1991 when they started shipping their computer hardware in cow-spotted boxes.

Gateway sells to specific markets including Home & Home Office, Small Business, Gaming, Medium & Large Business, Government and Education. They do not use brand names to market products, instead using product models. They currently market a range of laptop products for the home markets including the NX100X, CX210, NX260X, NX560 and NX860 series.

They also market a range of desktops including the DX420, FX510, FX530, and Profile 6 series. These products are advertised as affordable and productive computers. The Profile 6 is an All-in-one system similar in design to Apple's iMac G5. Their lowest priced system is the DX420B Series, with a monitor sold separately.

Gateway currently sells seven LCD-based computer monitors as of September 25, 2006, including one 15" model, two 17" models, three 19" models, and one 21" model. Some include USB ports.

Shortly after the dot com bubble, Gateway entered the consumer electronics market, manufacturing digital cameras and other devices. None of these products were successful, and Gateway has stopped production and sales of them as of 2006.

Gateway also markets "Convertible Notebooks", notebook PCs combined with tablet PC technology including handwriting recognition with a stylus much like a personal digital assistant (PDA).

Gateway sells a line of low-end to medium-sized PC servers. These servers are manufactured by what was Advanced Logic Research, a former pioneer in PC servers, which was acquired by Gateway.
