Movable type is a printing technology that uses individual letters and characters made from metal or wood. These pieces can be arranged and rearranged to create different texts, allowing for the mass production of written material. This innovation significantly reduced the time and cost of printing compared to earlier methods, such as woodblock printing. Invented in the 15th century by Johannes Gutenberg, movable type revolutionized the spread of information. It enabled the rapid dissemination of books, pamphlets, and newspapers, contributing to the Renaissance and the Reformation. This technology laid the foundation for modern printing and publishing practices.
