3: Intel 4004
For Democratizing the Power of Computing
The first electronic computer filled an entire room. But something the size of a fingernail put all that power in people's hands: the Intel 4004. The predecessor to smaller, stronger, cheaper microchips, the 4004 showed it was possible to put all of a computer's processing onto a tiny slice of silicon. In doing so, it not only transformed existing devices, it helped create new ones.
