Many companies have made improvements in the video and several different classifications have been MDA, VGA, up to the current three-dimensional technology known as SVGA.

Before leaving SVGA technology, the first 2D/3D graphics card was launched in 1995. At that time there were a lot of competition in the market for graphics cards such as Creative, S3, Matrox and ATI to name a few.
