The Steam Engine allowed transportation across the country, and factories no longer needed to be located by rivers, instead they used the steam engine to power their machines. The auto mobile helped revolutionize and change completely how people travel, especially in America when Henry Ford made the first affordable automobile, not just the automobile. Karl Benz made the first automobile, but only the rich could afford it at the time. The Internet, of course, changed how people gather and give information, and today anyone with any sort of technology can learn about anything they want, and also give their own voice and opinions on topics. The Internet has definitely helped expand education and how people learn about current events.
Hopefully this helped, I know its brief but there wasn't much details given.
