How did typesetting evolve over the years?

Typesetting evolved from manual letterpress printing in the 15th century, using movable type, to mechanical typesetting machines in the 19th century, like the Linotype. The introduction of phototypesetting in the mid-20th century replaced metal type with photographic processes. Digital typesetting emerged in the late 20th century, allowing for computer-based design and layout, revolutionizing the publishing industry.
