In 2019, the revenue of digital advertising agencies across the United States was estimated at 17 billion U.S. dollars. Digital ad agencies’ revenues have been steadily increasing over the past five years.

Integrated advertising services

In 2018, U.S. ad agencies generated a substantial amount of their revenue through integrated advertising services, namely about thirty billion U.S. dollars. Advertising agencies brought in approximately twice as much revenue from integrated ad services in 2018, compared to the amounts generated in 2010. In 2018, about 8.1 billion U.S. dollars was generated through media buying services, ad agencies’ second-largest source of revenue. The amounts made through this source in the United States have increased by about thirty percent since 2010.

American ad agencies’ estimated expenses have also increased considerably in the past few years. Expenditures of advertising agencies in the United States grew from just under 28 billion U.S. dollars in 2014 to about 36 billion in 2018.
