Digital advertising tops TV spending according to a study prepared for the Interactive Advertising Bureau by PwC US.

TV ads outlays for broadcast and cable was $70.1B, a three percent dip. Magazines ($20.9B) and newspapers ($17.0B) were both down, while radio ($17.6B) showed a slight uptick.

Search ads ($40.6B) accounted for 47.7 percent of digital revenues, while banner ads ($27.5B) comprised 31.2 percent of the total. Digital video pulled in $11.9B, a 33 percent jump, and accounted for 13.5 percent of digital ad spending. Social media advertising also grew, rising 36 percent to $22.2B.

Mobile is rapidly becoming dominant across the board on the digital side, surpassing desktop in the search, banner, video and audio sectors. Mobile advertising ($49.9B) rose 36 percent, and now represents 57 percent of the digital total.

While desktop revenues still grew, they did so at a slower rate, hitting $38.1B, up 6.1 percent from FY 2016’s $35.9B.

“Consumers are increasingly spending a tremendous amount of time with interactive screens and content,” said IAB CEO Randall Rothenberg. “Mobile capture more than half of the total digital ad spend last year and we can easily expect that share to continue to climb.”
