00:00 The question of whether Gutenberg actually invented the printing press requires more nuance than a simple yes or no.

01:46 Gutenberg was not the first person to create and use a printing press, as printing presses were already being used in China centuries before Gutenberg's time, but the difference was that Gutenberg used movable type instead of block printing.

03:09 Gutenberg was not the first person to use movable type, as it was already being used in China centuries before his time, but he improved upon it by using metal characters instead of clay.

04:42 The systems of printing developed in China and Korea predated Gutenberg, but were never put into widespread use due to linguistic and technical reasons.

06:18 Gutenberg's movable type printing press was unique in that it was developed with the intent to make a profit, unlike the systems of printing in China and Korea which were controlled by the emperor and not allowed to be used independently, and the political situation in Europe, with its competing states and religious factions, facilitated the spread and rapid evolution of printing.

07:44 Gutenberg's matrix and mold system for creating metallic type, along with his development of oil-based ink, were key innovations that allowed for the rapid creation of type and the establishment of a printing industry.

09:06 While the technology for printing may have originated in China, the practical printing system that spread worldwide can be attributed to Johannes Gutenberg.
