Here's a short subject about the transistor, made five years after they were invented. Three years after this, the men involved, shown in this short, won the Nobel Prize.
I still recall my brother, a decade later, soldering together transistors on a circuit board. Nowadays, the size of these tiny devices have become much smaller, manufactured via modern techniques into chips, which are the equivalent of hundreds of thousands of transistors, which are used to make computers. Indeed, computers are mentioned in this short as one of the possible applications of transistors. So they got that right.
