1954: IBM builds the first calculating machine to use solid-state transistors instead of vacuum tubes. IBM already had a business selling calculating machines, and it was humming along quite nicely.

The First Transistorized Computer . January, 1954: If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too.

Transistorized cars of the future may eventually have ignition systems with no points at all to go wrong. Their pulses of current will be generated by rotating magnets, ...

Multiplier photo-cells normally require a high tension supply of the order of 1000 volts. This supply is usually obtained from the electricity supply mains by means of conventional rectifiers and ...

According to Sonotone, the semi-transistorized instrument gets twice the normal service out of an A-battery and makes a standard B-battery last six months instead of the usual three or four weeks.
