The first transistor was invented at Bell Laboratories on December 16, 1947 by William
Shockley. This was perhaps the most important electronics event of the 20th century, as
it later made possible the integrated circuit and microprocessor that are the basis of
modern electronics. Prior to the transistor the only alternative to its current regulation
and switching functions (Transfer resISTOR) was the vacuum tubes, which could only
be miniaturized to a certain extent, and wasted a lot of energy in the form of heat.
Compared to vacuum tubes, it offered:
smaller size
better reliability
lower power consumption
lower cost
