The old processor architectures began to fall, first minis, then [[supermini]]s, and finally [[Mainframe computer|mainframes]]. By the mid 1990s, every computer made was based on a microprocessor, and most were microcomputers compatible with IBM PC. Although there was a time when every traditional computer manufacturer had its own proprietary micro-based designs there are only a few manufacturers of non-commodity computer systems today. However, super microcomputers (large-scale computer systems based on one or more microprocessors, like those of the IBM p, i, and z series) still own the high-end of the market.
=== Commodity Computing in the Present Day ===
As the power of microprocessors continues to increase, there are fewer and fewer business computing needs that cannot be met with off-the shelf commodity computers. It is likely that the low end of the supermicrocomputer genre will continue to be pushed upward by increasingly powerful commodity microcomputers. There will be fewer non-commodity systems sold each year, resulting in fewer and fewer dollars available for non-commodity R&D, resulting in a continually narrowing performance gap between commodity microcomputers and proprietary supermicros.
