Digital ad spend reached $57.9B in the first half of 2019, but growth has slowed (IAB report)

During the first six months of 2019, advertisers spent $57.9 billion on U.S. digital advertising, according to the latest report prepared by PwC for the Interactive Advertising Bureau (an online advertising trade group). Silverman suggested that one factor contributing to this is slowing growth in mobile and social advertising. To be clear, both sectors are up year-over-year: Mobile ads grew 29% to $30.9 billion, while social media spending increased 26% to $16.5 billion.
