What contribution did Gutenberg make to the development of communication?

Johannes Gutenberg revolutionized communication by inventing the movable type printing press around 1440. This innovation significantly increased the speed and efficiency of book production, making literature and information more accessible to the masses. As a result, it facilitated the spread of ideas, contributed to the Renaissance and Reformation, and laid the groundwork for the modern knowledge-based society. Gutenberg's printing press fundamentally changed how information was disseminated, leading to an unprecedented rise in literacy and public discourse.
