Consumer culture and marketing have profoundly shaped American society since the late 19th century. Mass production, urbanization, and rising incomes fueled the growth of consumer goods and services, while advertising and branding strategies evolved to influence purchasing behaviors. From department stores to TV ads, marketing techniques have adapted to new technologies and social changes. The rise of credit, suburbanization, and youth culture in the mid-20th century further transformed consumer habits, leading to today's digital-driven marketplace.
