[3] STB's first products were released in 1981 and comprised memory expansion boards and graphics enhancement cards for the Apple II.

By January 1996, STB employed roughly 815 workers: 153 in the United States, 12 in the company's three European offices (in London, Frankfurt and Paris), and about 650 in Juárez.

[1] In 1994, STB entered the growing 3D acceleration graphics card market with the introduction of the Power 3D System board, making use of 3Dlabs's Glint chip.

[9] In April 1997, the company acquired Symmetric Simulation Systems, a manufacturer of high-end 3D accelerator cards marketed to CAD/CAM users and multimedia CD-ROM authors based in Dallas, Texas, for $200,000.

[12] 3dfx Interactive, a graphics chip maker, announced the acquisition of STB Systems in December 1998, in a stock swap valuated at $141 million.

[14] Following the merger, conditions at 3dfx deteriorated rapidly, and the company's intellectual property was acquired by their largest competitor Nvidia in 2000, 3dfx properly dissolving in 2002.

Industry analysts considered their acquisition of STB a major reason behind 3dfx's decline, as it resulted in third-party manufacturers transforming from investors in the development of 3dfx's products (a significant source of revenue) into competitors; these companies in turn began purchasing from Nvidia for their 3D accelerator chips.
