Computer Chips replaced transistors in the early 1980s, while transistor chips remained dominant sometimes into the 2000s
The 1990 recession caused a level of cutbacks in the semiconductor industry, leading to downsizing. After this period, computer chips became cheaper and more powerful than before due to advancements made by companies such as Intel. This led other companies like IBM to start using them for their custom computer systems. Transistor chips are still used today but are much less common than they were prior to the introduction of computers into the home market in the late 1970s-1980s.
