During the 1980s and 1990s a relatively large number of companies appeared selling primarily 2D graphics cards and later 3D. Most of those companies have subsequently disappeared, as the increasing complexity of GPUs substantially increased research and development costs. Many of these companies subsequently went bankrupt or were bought out. Intel and VIA Technologies remain as producers of primarily integrated solutions, while Matrox targets niche markets. Amongst the notable discrete graphics card vendors, ATI Technologies — acquired by AMD in 2006 and since renamed to AMD — and NVIDIA are the only ones that have lasted. ==Defunct graphics chip makers== These companies designed graphics chips and cards. *3Dfx - Assets were acquired by NVIDIA during its Chapter 11 bankruptcy *3Dlabs - Merged with Creative Labs' personal entertainment division to form ZiiLABS *Ageia - acquired by Nvidia *Ark Logic *ArtX - acquired by ATI Technologies *ATI Technologies - merged into and renamed AMD *Avance Logic - acquired by Realtek *BitBoys - acquired by ATI Technologies *Chips and Technologies - acquired by Intel *Chromatic Research - acquired by ATI Technologies *GigaPixel - acquired by 3Dfx *Gemini Technology - went bankrupt, acquired by Seiko Epson to form the Vancouver Design Center *Headland Technologies - division of LSI Logic's Standard Products Group in late 1990s, assets sold to SPEA *IXMICRO - produced video cards for Macintosh and Macintosh clones *MOS Technology - produced the VIC and TED line of graphics chips, owned by Commodore International. *Number Nine Visual Technology (originally named Number Nine Computer Corp.) - pioneer in the graphics industry, developed 1st 128-bit graphics processor.
