Genuine folk culture was colonized and extinguished by commodification from the midnineteenth century

Evidence

It would seem essential to distinguish the emergent forms of a new commercial culture — beginning with advertisements and spreading on to formal packaging of all kinds, from products to buildings, and not excluding artistic commodities such as television shows (the “logo”) and best-sellers and films — from the older kinds of folk and genuinely “popular” culture which flourished when the older social classes of a peasantry and an urban artisanat still existed and which, from the midnineteenth century on, has gradually been colonized and extinguished by commodification and the market system. — Fredric Jameson, Postmodernism, or, The Cultural Logic…, 192
