Which was the World's First Microprocessor ?

In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor. After the invention of integrated circuits revolutionizedcomputer design, the only place to go was down -- in size that is. The Intel
4004 chip took the integrated circuit down one step further by placing all the parts that made acomputer think (i.e. central processing unit, memory, input and output controls) on one small chip. Programming intelligence into inanimate objects had now become possible.
