Silicon Graphics, which produced computer hardware and software, peaked at a $7B market cap in 1995 and filed for bankruptcy in 2006. The addition of 3D graphic capabilities to PCs, and the ability of clusters of Linux- and BSD- based PCs to take on many of the tasks of larger SGI servers, ate into SGI’s core markets. The porting of Maya to Linux, Mac OS and Microsoft Windows further eroded the low end of SGI’s product line.
