The World Wars inspired scientists to think of bigger and better machinery. All wars fought after World War II have used more machinery and fewer humans. Since so many people had died in the World Wars, scientists wanted to develop machines that would take over much of the work. Also, after World War II, factories began producing cheaper goods in larger numbers. This changed transportation. From animal-drawn carriages, which had been the only land vehicles for thousands of years, trains, cars and aircraft became common. Space studies also improved, originally for military reasons. Within 25 years of World War II ending, man had landed on the moon. Wired communication and signalling like Morse code and semaphore were not used any more.
