This was the decade of World War II (the first half of the decade), and the beginning of the Cold War Era (the second half of the decade). Some historians, including my college professors, say that World War II could be called World War I, Part 2 because part of the reason it started was that the post-war treaties and reparations from World War I left Germany’s economy crippled and the people desperate. Old conflicts that had never completely resolved resurfaced. The rise of dictators and the expansionist policies of the Axis powers led to a war that was eventually fought in battles all over the world as each side called in its allies once again.
By the end of the war, the United States had developed nuclear weapons and used them against Japan. This time, post-war settlements and power struggles ended up dividing the world into large sections controlled by competing political ideologies: communist countries, particularly Russia (the Soviet Union) and those loyal to Russia or under Russian control, vs. capitalist countries, particularly the United States and western Europe and countries influenced by those regions. This was the basis for the Cold War. The two sides began competing against each other for economic and technological superiority, using the threat of nuclear weapons to keep each other in check in a dangerously precarious balance of power. Countries outside of those two main political rivals were called “Third World” nations because they were not part of either of the two most influential groups or their power struggle. (Capitalist countries were considered “First World”, and communist countries were the “Second World.”) Third World nations were less affluent and not part of the technological race, leading to the modern conception of the term of “developing” countries.
Culturally, this was the era of big band music, and swing was still popular. Radio was still popular, and radio shows came in great variety. Many of them included references to the war or messages urging people to buy war bonds and support the war effort. Radio shows were transmitted overseas for the entertainment of the troops as well.
People could go to movie theaters to see not only the latest films (still mostly in black-and-white, although color film was gradually taking hold), but also news reels and cartoons. Film noir, crime movies with dark themes and images, became popular. Movies also often featured patriotic and war themes with announcements for people to buy war bonds.
After World War II, there was a sudden rise in new births, which people began calling the “Baby Boom.” Because of this sudden increase in births, children, children’s services, and products for children and young people became particularly important for the following decades.
