Invented in 1971 by Intel, the 4004 chip was the first microprocessor to be sold on the open market. It was a 4-bit CPU and could process up to 92,000 instructions per second, which translates to one instruction per 11 microseconds, dramatically increasing the speed of commercial computers. Although microprocessors had been around for a short amount, the Intel 4004 opened up the market significantly for computers aimed at homes and businesses, as opposed to scientific research.
