Integrating Intel: trademarks as key ingredients

A microprocessor is an important piece of technology. A computer’s processing power and its size used to be in proportion; the 1946 Electronic Numerical Integrator and Computer, which was used to calculate artillery firing tables, weighed 30 tonnes. The invention of the microprocessor—a single integrated circuit—meant that the functions of a computer’s central processing could be handled by a tiny chip, rather than an array of vacuum tubes, crystal diodes, relays, resistors, capacitors and hand-soldered joints.
