And, as of December 15, 2000, 3dfx is wholly owned by nVidia.
According to press releases about the transaction, the deal had apparently been in the works for some time. nVidia purchased 3dfx for approximately $112 million dollars in cash and securities, gaining rights to the company's assets, including brand names, the research done by both 3dfx and Gigapixel, all remaining chip inventory, and patents.
Pundits are already commenting that this deal is really just an out of court settlement for nVidia.
