answer: It was the Qin Emperor who equipped large armies with weapons with a sophisticated trigger mechanism made of interchangeable parts, and the Venetian Arsenal that produced nearly one ship every day , in what was effectively the world 's first factory. Mass production in the publishing industry has been commonplace since the Gutenberg Bible was published using a printing press in the mid-15th century.
