Ted Hoff at Intel invented the microprocessor to fulfill a contract from Busicom for calculator chips. The set of chips included a central processing unit chip called the 4004, which came to be known as the first microprocessor. While the 4004 had limited capabilities, Intel continued developing microprocessors through the 8008, 8080, 8086 and beyond, with each new model offering increased capabilities. These microprocessors helped establish Intel as the dominant maker of microprocessors, outcompeting early rivals like Motorola.
