Why computers began commercialization in the trend in 1950 why not 1940?

Computers began commercializing in the 1950s primarily due to advancements in technology that made them more practical and affordable for businesses. In the 1940s, computers were largely experimental, expensive, and limited to research institutions and government projects. The introduction of transistors in the late 1940s and early 1950s replaced bulky vacuum tubes, leading to smaller, more efficient machines. Additionally, the growing demand for data processing in industries after World War II spurred investment and development in commercial computing.
