Transistors Take Their First Steps Into the Real World
Raytheon built the first commercially available point-contact transistor -- made out of germanium -- in 1949. Known as the CK703, it never was all that easy to produce and wasn't particularly successful.
Raytheon had better luck a few years later with a junction transistor. In 1953 they put out the very first mass-produced transistor, also made out of germanium. It was called the CK722. The main body of the transistor was less than half an inch long.
