Answer the following Q with stream of consciousness. Context: By the late 1960s, designers were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. Building on an earlier Busicom design from 1969, Intel introduced the first commercial microprocessor, the 4-bit Intel 4004, in 1971, followed by its 8-bit microprocessor 8008 in 1972. In 1969, Lee Boysel, b 8-bit arithmetic logic units (3800 / 3804) he designed earlier at Fairchild, created the Four-Phase Systems Inc. AL-1, an 8-bit CPU slice that was expandable to 32-bits. In 1970, Steve Geller and Ray Holt of Garrett AiResearch designed the MP944 chipset to implement the F-14A Central Air Data Computer on six metal-gate chips fabricated by AMI.

Question: who introduced the first micro processor in 1971?
To answer this question, we should know that: Building on an earlier Busicom design from 1969, Intel introduced the first commercial microprocessor, the 4-bit Intel 4004, in 1971, followed by its 8-bit microprocessor 8008 in 1972. Therefore, the final answer is Intel.
