Which development allowed mass advertising to scale widely?

• A. Radio
• B. Internet
• C. Television
• D. Gutenberg Press Allowed

Answer: (D)

Mass advertising scales when messages can be reproduced cheaply and distributed widely. The Gutenberg printing press introduced movable type and mechanized printing, which made it possible to produce large runs of text and images at a fraction of the cost and in a much shorter time than hand-copying. This lowered the barrier to creating and sharing ads, allowing newspapers, pamphlets, catalogs, and posters to reach broad audiences far beyond a single workshop or village. Once printed media became widespread, advertisers could place messages in many copies circulating in multiple towns, fostering a market for advertising revenue and giving businesses a way to reach mass audiences.

Later innovations like radio, television, and the internet built on this foundation by adding audio/visual formats and instantaneous global distribution, but the ability to mass-produce written content in wide quantities is the development that first enabled mass advertising to scale.
