STB Systems, Inc., was an American graphics adapter card manufacturer active from 1981 to 1999. Initially a manufacturer of various expansion cards for the Apple II, the company quickly leaned into the graphics accelerator market for IBM PCs and compatibles, owing to the IBM PC's more open architecture. STB went public in 1995 and was once the second-largest global vendor of multimedia computer products. In 1999, the company was acquired by 3dfx Interactive.
