Television's post-World War II boom in the United States saw an extraordinary rise in TV ownership, with the number of sets in American homes soaring from 6,000 in 1946 to over 12 million by 1951. This rapid growth, driven by rising incomes and the increasing affordability of television sets, was preceded by significant technological advancements in the 1920s and 1930s, a wartime pause, and a post-war surge in broadcasting and programming that laid the foundation for television's Golden Age and its enduring legacy in the digital era.
