The term "Gutenberg Revolution" refers to the monumental transformation in the production and dissemination of information brought about by Johannes Gutenberg's invention of the movable type printing press in the mid-15th century. This technological innovation enabled the mass production of books, significantly lowering their cost and making literature and knowledge more accessible to the general populace. The Gutenberg Bible, printed around 1455, was among the first major books produced using this technology. Its impact extended beyond literature and learning, contributing to the spread of ideas during the Renaissance and Reformation, and fostering increased literacy across Europe.
