In 1886 Alexander Graham Bell had invented the very first telephone!
The first telephone was changed from a big box with a black hole to a small iPhone or smartphone. Back in 1886 there was this big long cord with a little black talking thing then there was this box with with a holder! "Oh" and the long cord connected to another one and you would hear it. Today there is a phone with games, Emails, calling, texting and more!
People can call all around the world instead of writing a letter!
