Out-of-home advertising spent decades as the slowest-moving line on a brand’s media plan. Booking a board meant phone calls to regional vendors, faxed contracts, and a lead time measured in months and weeks rather than days.

That version of the channel is disappearing quickly. The formats look different, the buying process looks different, and the brands showing up on billboards are not the ones that dominated them five years ago.

Here are six advertising trends that brands should keep an eye on this coming year.

1. Buying moves to dashboards rather than phone calls

The biggest shift in out-of-home has little to do with the boards themselves. It is that securing one now looks like buying any other media, with searchable inventory, side-by-side comparisons, and contracts handled entirely in a browser.

That is exactly what a billboard advertising agency operating as a software platform makes possible: replacing a chain of vendor calls with a single place to search inventory and commit to space.

Launch timelines compress accordingly, which matters most when a campaign is tied to a product release or a seasonal push that cannot wait on a paper contract.

2. Programmatic buying scales up fast

Programmatic buying took longer to reach out-of-home advertising than it did display or connected TV, but the gap is closing fast. Research from the supply-side platform VIOOH projects that programmatic spending in the channel will climb roughly 49% over 18 months.

That growth matters mostly because of who it lets in. A brand testing three screens in a single metro no longer needs a dedicated out-of-home buyer on staff to do so.

3. Digital screens keep taking budget share

Static vinyl still carries plenty of weight, but digital inventory is where the growth is concentrated. The OAAA reported that digital formats grew 12.9% year over year and accounted for 36% of total out-of-home revenue in the first quarter.

Digital transit and street furniture are climbing fastest within that mix, which points toward screens people encounter on foot or on a platform rather than through a windshield at highway speed. Screen networks are also reaching places that carried no advertising at all a few years ago, from gym floors to grocery aisles to charging stations.

4. Tech and AI brands are driving new demand

The advertiser mix is shifting alongside the formats. That same quarterly report showed spending from computer, software, and internet services brands surging past triple-digit growth, with AI companies among the fastest-rising buyers in the entire channel.

The logic behind it is straightforward. A company selling something most people have never used needs broad public awareness first, and a billboard reaches an audience that no targeting parameter can assemble online.

5. Measurement starts to look like digital

The old knock on out-of-home was that nobody could prove what it actually did. Mobile location data has largely closed that gap, letting brands tie exposure to store visits, app installs, or a lift in search traffic within a defined radius.

Attribution still is not as tidy as a click-through report, and it probably never will be. But it is now close enough that out-of-home competes for performance budgets instead of sitting in a separate awareness bucket nobody scrutinizes.

Brands that measure consistently also learn which specific locations work for them, which makes the second campaign a considerably smarter buy than the first.

6. Creative gets built for the camera

A growing share of a billboard’s value appears elsewhere rather than on the road. Brands increasingly design boards to be photographed and reposted, treating the physical placement as the start of a campaign rather than the whole.

That changes what makes a board work. A sharp one-line message in a dense, walkable neighbourhood can outperform a much larger highway placement that nobody bothers to pull out a phone for.

Placement and creative are increasingly planned together for that reason. A board that photographs well in one neighbourhood can fall flat two miles down the road.

Planning for a channel that stopped standing still

None of these shifts makes out-of-home a replacement for digital spend. They make it a far more practical complement, one that no longer demands a specialist, a six-figure commitment, or a month of lead time just to run a test.

The brands benefiting most are the ones treating it as a routine line item rather than an occasional splurge reserved for product launches. Buying is faster, measurement is sharper, and the barrier to entry keeps dropping.

Everything that once made out-of-home difficult to buy has quietly been engineered away. What remains is the format doing what it always did well: putting a message in front of people while they are out living their day.
