Johannes Gutenberg and the Mass Production of Ideas | The Hero Show, Ep 122

Before 1450, all books in Europe were laboriously written by
hand. Gutenberg changed that with one invention: the moveable
printing press. Thanks to his creation, within fifty years
businesses in Europe were producing millions of books.

The dissemination of ideas led to radical improvements in the
culture and helped bring about the Renaissance, the Reformation,
and the Age of Enlightenment.
