How did the invention of the Gutenberg press change life in Europe?

Obviously the answer to this question is many fold. One area of change was to expand the availability of books to the developing middle class in major cities, especially port cities where trade was creating a new class of wealth. Additionally, it opened the door for the mass reproduction of major works, most notably the Bible. This opened the door to individual ownership of a book which previously was meticulously copied by hand and very expensive. It also opened the door to individual interpretation which split the Church and created whole new streams of Christian thought based largely on modern interpretation within a European, rather than a Latin or Mediteranean cultural existence. It afforded for the expansion of academia through the commonality and low cost of texts books which gave the developing middle class more power through education. It provided for a whole new class of entertainment for the common man by the introduction of the novel and it helped immeasurably to expand literacy in just about every nation. All in all, one of the most significant inventions in history!
