Intel's introduction of single chip microprocessors containing the complete CPU of a computer on one monolithic integrated circuit, starting with their four bit 4004 microprocessor in 1971 followed by their eight bit 8008 microprocessor in 1972. Interestingly both of these microprocessors were originally designed as proprietary products to be sold only to the customer that requested them, while the 4004 was indeed used in the product it was designed for (a business desk calculator) the customer became dissatisfied and agreed to sign the rights back to Intel to sell the 4004 on their own, but the 8008 (and a similar chip designed by Texas Instruments at the same time) was completely rejected and the customer built his product using just standard 7400 series TTL chips so Intel was free to sell the 8008 on their own.

The 8008 eventually lead to the 8080, the modern 80x86 family (including Pentium, Celeron, etc.), and the latest Duo Core, i5, i7, and other multicore Intel microprocessors.
