Answer:
Printing press
Step-by-step explanation:
The Printing press was invented by German goldsmith Johanes Guttenberg in 1440. It had a mechanism that allowed the copy of books at a much faster rate than ever before, since up until that point, books have to be copied by hand.
The printing press increased the amount of books that were available to the public, leading to a rise in literacy rates, the spread of works by authors like Shakespeare among a larger amount of people, and the expansion of secular ideas.
