What significant invention did Gutenberg create that had an important impact on communication?

The invention that had a significant impact on communication is the moveable type printing press. Johannes Gutenberg's printing press, developed in the mid-15th century, revolutionized the way information was disseminated. It enabled the mass production of books and other printed materials, drastically reducing the cost of printing and making literature accessible to a much wider audience. This democratization of knowledge fostered literacy and contributed to the spread of new ideas during the Renaissance, Reformation, and beyond.

The moveable type printing press also facilitated the preservation of languages and cultures by allowing for the standardization of texts. This technological advancement laid the groundwork for modern communication methods and played a crucial role in shaping public opinion, education, and the sharing of information.
