First Advertisement for Microprocessor Appears
The first advertisement for a microprocessor, the Intel 4004, appears in the journal Electronic News. The chip was designed by a four-person team at Intel, a start-up company founded by Gordon Moore and Robert Noyce a few years earlier. Intel engineers Federico Faggin, Ted Hoff, Stan Mazor, and Masatoshi Shima designed the 4004 while undertaking a custom circuit design for Busicom, a Japanese calculator maker.
