U.S. digital advertising revenues reached $57.9 billion during the first six months of 2019—a spending record for the first half of the year—according to the latest IAB Internet Advertising Revenue Report released by the Interactive Advertising Bureau and prepared by PwC US. The total marks a 17 percent year-over-year increase from the first half of 2018. While increased growth is continuing in digital, the report cautions that resources associated with complying with the California Consumer Privacy Act (CCPA) and myriad other data regulations proposed by states will likely have a negative impact on businesses in the digital marketplace.

“The uptick in revenues continues to be significant. IAB has joined forces with Privacy for America to advocate for national laws that will make it easier to protect consumer privacy, while continuing to fuel the digital economy,” says Randall Rothenberg, CEO, IAB. “Further, innovation will likely be stifled when companies are forced to redirect resources to comply with an unwieldy patchwork of state-by-state regulations.”

A key driver of the revenue growth spotlighted in the report was video advertising, which was cited as a major contributor to growth as spending climbed 36 percent year-over-year to a total of $9.5 billion for the first half of 2019. IAB notes that with the growing pool of cord-cutters and “cord-nevers” driving the expansion of connected television (CTV), social video stories and other forms of non-traditional video content have advertisers increasing their investment in CTV.

IAB’s study found that mobile advertising is continuing its explosive growth, reaching $40 billion for the first half of the year—a 29-percent increase from the $30.9 billion spent on mobile during the same time period in 2018. Audio advertising spending is also rising with the emergence of smart speakers, up 30 percent year-over-year to a total of $1.2 billion for the first six months of 2019, and advertisers spent $1.7 billion on rich media ads during the first half of the year, 20 percent more than they did during the first half of 2018.

“Digital video growth has played a key role in giving 2019 the strongest opening six months in digital’s history,” says Sue Hogan, senior vice president, research and analytics, IAB. “Increasingly, advertisers are turning to social video stories and connected TV to reach a growing audience of ‘cord-nevers’—a younger cohort who’ve never subscribed to cable television and cannot be reached via linear TV ads. Indicators show CTV and addressable TV are on the rise.”

Hogan adds, “Our latest report confirms that the digital advertising industry remains one of the strongest and most dynamic sectors of the U.S. economy. At nearly 17-percent growth from the prior half year, the digital advertising industry is still far outpacing all other ad-supported mediums. However, the pace of growth is showing signs of slowing. As smartphone ownership nears saturation and social media matures, the industry is focused on new channels for growth such as connected TV, augmented reality and the vast potential of 5G.”
