Grub Street is a term that originated in 16th-century London, referring to a street known for its many writers and publishers. It became synonymous with low-quality writing and hack journalism, as many struggling authors and journalists worked there to make a living. The name has since evolved to represent any place or situation where mediocre writing is produced. Today, "Grub Street" is often used to describe the world of commercial writing, particularly in the context of journalism and publishing. It highlights the challenges faced by writers who must balance artistic integrity with the demands of the market.
