Inventions That Changed History

Do you want to learn about inventions that changed history? Then keep reading!

1) Radio

Guglielmo Marconi invented the first radio in 1895. It used radio waves to send messages instead of wires. The radio became an important means of communication in the 20th century. However, the message only went one way, so people couldn't use it to have conversations. Instead, they used it to broadcast important messages, songs and stories.

2) The Internet

There wasn't one inventor of the Internet and the idea started longer ago than you think. Since the 1950s, many scientists were working to create the networks of electrical connections all over the world - what we call the Internet today. We can use the Internet to communicate with text, sound or even video. Some people say it is the most important invention in history. What do you think?

3) Smartphone

Alexander Graham Bell invented the telephone in 1876, and people kept improving his invention over time. The technology company IBM developed the first smartphone in 1993. However, it wasn't until Apple created the iPhone in 2007 that phones with screens became popular. Today, over 7 billion people have smartphones.
