What are two effects of the invention of the printing press?

The invention of writing was the dawn of the information revolution. This great technological advance allowed news and ideas to be carried to distant places without having to rely on a messenger's memory. Like all inventions, writing emerged because there was a need for it. In Mesopotamia, it was developed as a record-keeping vehicle for commercial transactions or administrative procedures. There are also texts that served as "copy books" for the education of future scribes. Eventually, cuneiform script was used to produce some of the greatest literary works in recorded history.
