before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
The Invention of the Telegraph by Joseph Henry in 1831 led to the invention of the phone.
The steam engine
Exactly that...that one invention leads to another invention. For example. The invention of the car, led to the invention of the assembly line
The cotton gin!
Paper making
They developed the first working transistor at Bell Laboratories in 1947, which revolutionized the field of electronics and paved the way for modern technology such as computers and smartphones. This invention marked the beginning of solid-state electronics and led to the eventual replacement of vacuum tubes with much smaller and more efficient transistors.
The invention of the transistor was the first big event to lower cost and size. This was followed by the invention of the integrated circuit, which led to CPUs, GPUs, etc. cw: The first transistor invented was MUCH larger than the new miniature tubes, invented by GE.
Most likely the Silicon Chip.

The Walkman led to the invention of the iPod.
William B. Shockley is best known for co-inventing the transistor in 1947, which revolutionized the field of electronics and led to the development of modern computer technology. This breakthrough technology eventually earned him the Nobel Prize in Physics in 1956.
