Question

how did the sale of novel expand in the modern age

Answer 1

On the older side, Le Morte d'Arthur by Thomas Malory, which was published in 1485, is sometimes called the first English novel. Other people say the first English novel was Don Quixote, published in 1605; Oroonoko, published in 1688; Robinson Crusoe, published in 1791; or Moll Flanders, published in 1722.
