Digital OOH drives momentum with 7.5% increase, OOH revenue increases 4.5% from previous year

WASHINGTON, DC — Out of home (OOH) advertising revenue surpassed $9.1 billion in 2024, a 4.5% increase from the previous year, according to newly released data from the Out of Home Advertising Association of America (OAAA), the leading trade group representing the entire OOH advertising industry. This is the first time OOH advertising revenue has exceeded the $9 billion mark in the history of the medium.

Digital OOH (DOOH) accounted for 34% of total OOH ad spend and grew by 7.5% in 2024, reinforcing its role as a major growth driver. While DOOH continued to fuel industry momentum, OOH also saw gains across key segments, including Billboards, Transit, and Street Furniture. Transit led the category growth with a 10.6% increase.

In 2024, half of the top ten advertising product industries grew by double digits, including (in order of percentage growth): Communications, Government Politics & Organizations, Retail, Automotive Dealers & Services, and Local Services & Amusements. Notably, political advertising generated record OOH spending in a presidential election year.

“This marks the first time OOH revenue has exceeded $9 billion, signaling the continued strength and momentum of out of home advertising,” said Anna Bager, President and CEO, OAAA. “As brands double down on innovation and creativity, OOH remains a powerful driver of engagement across industries. The ongoing adoption by technology and direct-to-consumer brands underscores the channel’s expanding influence. This research reinforces what we already know—OOH is delivering results at every level, from hyperlocal activations to national and global campaigns.”
