It was the other way around. See eg https://www.maximum-progress.com/p/the-printing-press-nfts-a... - "In 1843 alone 14,000 new works were published in Germany, close to the publication rate today in per capita terms." .. "Publishers knew that once a manuscript was out in public it could be cheaply copied by other printing press owners, so instead they sought out new manuscripts in pursuit of a first mover advantage on publishing. In addition, they created fancy special editions for wealthy customers to differentiate their product from what other printers could easily copy with mass market paperbacks."
