Do you enjoy reading books?
You may have a shelf of books at home or in your classroom. Libraries have rows and rows of books.
Before Gutenberg made the printing press, books had to be copied by hand. It could take months to make one book! They were expensive and rare, and only a few people knew how to read.
After Gutenberg invented a faster way of producing books, they eventually became less expensive and more common, and more people learned to read.
The way we make books today is a result of Gutenberg inventing the printing press.
