Vectorbeam was an arcade game manufacturer active in the late 1970s who specialized in vector graphics-based arcade games. It was formed after splitting off from its primary competitor, Cinematronics, and disappeared after re-merging with them soon after.
Founded by Larry Rosenthal (game designer) and based on his patent for a custom arcade vector display, Vectorbeam was in direct competition with other arcade game manufacturers. The company ceased operations soon after poor sales of its Barrier arcade game, and sold its assets to Cinematronics
