OOH Has Won Back Attention. Now It Needs to Prove It
Attention is becoming advertising's most valuable currency
Advertising has spent the last two decades becoming extraordinarily good at measuring almost everything. An online campaign can tell a brand how many times an advert was served, how many people clicked it, how long they stayed on a page, whether they visited a product, whether they added something to a basket and, in many cases, whether that exposure ultimately contributed to a sale.
Yet somewhere along the way, advertising developed another problem. Being measurable does not necessarily mean being noticed.
Consumers now live inside an almost continuous stream of screens, notifications, feeds, videos, banners, emails and sponsored content. The number of opportunities for advertisers to reach people has exploded, but the amount of human attention available has not. That imbalance may turn out to be one of the defining advertising challenges of the next decade.
It is also creating an intriguing opportunity for Out of Home advertising. OOH already operates in the physical world, outside the browser tabs and social feeds where consumers have become highly practiced at filtering commercial messages. The market is growing strongly. What it still needs is a better way to connect real-world exposure with evidence of real-world attention.
Screens have become ubiquitous. Attention has not.
Think about how many screens the average person encounters before lunchtime. There is the phone beside the bed, the television, a laptop or desktop computer, screens on public transport, displays in the office, digital menu boards, self-service checkouts, tablets, information screens and advertising displays. Then the phone comes back out whenever there is a spare moment.
According to DataReportal's Digital 2025 Global Overview Report, adult internet users spend an average of 6 hours and 38 minutes online every day. DataReportal notes that this is roughly 40% of waking life spent actively engaging with digital devices and services.
That figure only describes internet use. It does not count every television, digital billboard, retail screen or other display encountered throughout the physical world. Screens have become so common that the presence of a screen is no longer, by itself, a reason to look at it.
This does not mean traditional screens have stopped working. Great creative on a conventional display can still be extremely effective. The problem is that screens no longer carry the novelty they once did. A rectangle displaying moving images was once remarkable technology. Today it is the default interface through which much of modern life is experienced.
Consumers have become exceptionally efficient at filtering what appears on those rectangles. We scroll past advertising. We skip videos. We close pop-ups. We switch tabs. We look at our phones while television adverts play. We subconsciously separate the content we want from the commercial messages surrounding it.
For brands, the challenge is increasingly not whether an advertisement can technically appear in front of somebody. It is whether that person actually gives it any attention.
An impression is not the same as attention
This distinction becomes especially clear in digital advertising. The industry has developed sophisticated standards for delivery, impressions and viewability, but none of those automatically proves that a human being actually looked at the advertisement.
Lumen Research reports that approximately 70% of digital ads measured as viewable are not actually viewed. In other words, an advert can satisfy a technical viewability standard while receiving no meaningful visual attention from the person on the page.
That gap matters because advertisers ultimately buy media to influence people, not pixels. If an advert was delivered but ignored, the technical impression has value for accounting, but it tells only part of the commercial story.
Lumen's campaign work also suggests that attention itself can have economic value. In one head-to-head programmatic test, an attention-led buying approach produced 104% more viewed ads, 110% higher ad view time and a 40% lower CPM than the control campaign within the same budget. The case study is a single campaign example, not a universal benchmark, but it illustrates why advertisers are increasingly interested in attention as a planning and optimisation signal.
The advertising question is therefore evolving. For years the industry's great challenge was: Can we put an advert in front of the right person? Increasingly, the harder question is: Can we make them actually notice it?
The physical world is becoming more valuable
Out of Home advertising has something that online advertising cannot fully recreate. It exists in the real world. A large-format display occupies physical space. A shopping-centre installation becomes part of the environment. An airport execution can dominate the passenger journey. A spectacular site can turn advertising into something people photograph, discuss and remember.
A billboard cannot be closed with an X. A shopping-centre installation cannot be scrolled past in quite the same way as a sponsored social post. This does not make every OOH campaign effective. Creative, location, scale, context and format still matter enormously. But physical media has a fundamentally different relationship with its audience.
Advertisers are putting serious money behind it. According to the World Out of Home Organization's Global OOH Expenditure Report 2026, global OOH spend reached $54.2 billion in 2025, up 15% on 2024. OOH represented 5.1% of total global advertising expenditure, and WOO forecasts spend rising again to $56.4 billion in 2026.
In Great Britain, the scale of the medium is equally striking. Route's Q3 2026 data estimates that OOH reaches 96.94% of adults aged 15 and over in a typical week, equivalent to 53.89 million people. Route estimates 14.07 billion weekly impacts across 374,333 measured frames under its headline schedule assumptions.
OOH is not a legacy medium waiting to disappear. It is a large, resilient and growing advertising market with almost universal weekly reach in Great Britain.
But there is a paradox. The market is growing at the same time as much of its infrastructure is still moving through a long technological transition.
More than half of global OOH revenue is still non-digital
The wider advertising industry talks constantly about artificial intelligence, automation, real-time optimisation, dynamic creative and programmatic media. Yet globally, the transformation of OOH from static to digital remains incomplete.
WOO reports that Digital Out of Home generated approximately $25.5 billion in 2025, equivalent to 47% of global OOH revenue. That means around 53% of global OOH revenue still came from non-digital formats. WOO forecasts digital's share reaching 49% in 2026, putting the market close to the point where digital could overtake static globally for the first time.
This is a remarkable position for an industry operating alongside advertising platforms capable of changing creative instantly and analysing campaigns almost continuously. It does not mean OOH is technologically primitive. Some of the world's largest media owners operate sophisticated digital networks, dynamic content systems and advanced audience platforms. What it demonstrates is simply the scale of the transition still underway.
Even programmatic DOOH remains relatively young at global scale. WOO's independently aggregated pDOOH study, conducted with PwC across twelve supply-side platforms and more than forty markets, estimates that programmatic DOOH reached $1.339 billion in 2025, around 7.0% of global DOOH advertising spend. The study provides one of the clearest recent benchmarks for how much room remains for automation to grow.
OOH is already a $54.2 billion industry. Its technological transformation is nowhere near finished.
OOH does not have a data problem. It has a direct-measurement opportunity.
It is tempting to say that OOH is not measured, but that would be wrong. Established audience currencies provide highly sophisticated planning data. In Britain, Route combines travel behaviour, visibility modelling and more than 25 years of eye-tracking research to calculate the likelihood that people exposed to a poster or screen actually saw it.
Route explicitly describes itself as an attention-based currency. Its methodology adjusts audiences using the likelihood of seeing an advert, rather than relying on a simple opportunity-to-see assumption.
That is materially more sophisticated than merely counting the people who passed a location. But it is still different from directly measuring what happened in front of an individual display.
Route's own measurement framework makes the distinction clear. Route provides the core exposure measure for who had a realistic opportunity to see an ad, while attention metrics such as dwell time and attentive reach can be extended with sensors or bespoke research. The framework also shows how campaign analysis can progress through consideration, action and effectiveness using additional data and modelling.
This is not a weakness in OOH measurement. It is an opportunity to add another layer.
Industry-level measurement can tell advertisers how many people were likely to see a campaign. Display-level analytics can help answer a different question: what happened when people actually encountered this specific experience?
What if the display itself could measure attention?
Imagine a holographic advertising installation inside a shopping centre. Thousands of people might move through that part of the building during a day. Traditional audience measurement can provide a strong understanding of the potential audience around that location. But the display can potentially add a more immediate behavioural layer.
How many people were present around the display? How many stopped? How long did they remain? Did one creative hold attention longer than another? Did engagement change by time of day? Did a particular campaign generate a higher dwell time than the campaign that ran before it?
Those questions shift the conversation from theoretical exposure towards observable engagement.
Importantly, measuring these signals does not require identifying the individuals involved. There is a significant difference between measuring anonymous behaviour and identifying a person. A privacy-conscious system can measure presence and dwell time without needing to know someone's name, identity or personal information.
At Miirage, that distinction is central to the measurement proposition. The purpose is not to know who is standing in front of the display. The purpose is to understand whether the experience earned attention and how long that attention lasted.
Dwell time changes the meaning of an impression
For experiential media, dwell time is particularly interesting because an experience is inherently about duration. Someone walking past an advert for half a second has had a completely different interaction from someone who stops and watches for 20 seconds, even if both people appear somewhere inside an aggregate audience number.
Consider two campaigns installed in the same location. Campaign A attracts 1,000 viewers who remain for an average of four seconds. Campaign B attracts the same 1,000 viewers, but they remain for an average of 18 seconds. From a simple audience-count perspective, the campaigns look similar. From an attention perspective, they are radically different.
That difference creates useful feedback for brands and media owners. Creative can be compared according to how effectively it holds attention. Locations can be evaluated not only by the number of people passing through, but by the quality of engagement they generate. Campaigns can be tested and improved using behavioural evidence rather than relying only on exposure estimates.
Over time, metrics such as dwell could become especially valuable for experiential advertising because they help distinguish passive exposure from active interest.
The idea is simple: an impression tells you the opportunity existed. Dwell tells you something about what happened next.
This should complement OOH measurement, not replace it
Direct display analytics should not be presented as a replacement for established OOH currencies. They answer different questions.
Industry audience measurement provides the scale, consistency, demographic modelling and planning framework needed to compare locations and campaigns across a market. Display analytics can provide a much narrower but more immediate view of what happened around a specific installation.
Put simply, the two layers can work together:
- Audience measurement: How many people were realistically likely to see this campaign?
- Presence measurement: How many people were detected around this display?
- Dwell measurement: How long did people remain engaged?
- Campaign comparison: Which creative, location or time period held attention most effectively?
Together, those measures can give advertisers a richer picture of physical-media performance without pretending that one metric can explain the entire customer journey.
Why holographic advertising changes the equation
Measurement alone is not enough. You first need something worth measuring.
If consumers are surrounded by conventional screens throughout their waking lives, simply installing another rectangular display does not necessarily solve the attention problem. This is where holographic advertising becomes interesting.
A holographic experience introduces depth, movement and apparent physical presence into an environment dominated by flat media. A product can appear suspended inside a display. A person can appear physically present. An object can rotate through three-dimensional space. An AI avatar can welcome someone, answer questions or guide them through an experience.
The format behaves differently from another television mounted on a wall. That difference creates the possibility of interrupting the visual patterns people have learned to filter out.
This is the core Miirage proposition. It is not about adding more screens to a world that already has plenty of them. It is about creating a different kind of physical media, then measuring whether that difference actually earns attention.
From passive advertising to useful, interactive media
The opportunity becomes even greater when a holographic display moves beyond playback. Traditional OOH is primarily one-directional. The brand speaks and the audience sees. Interactive holographic displays can add another layer.
A customer could approach an AI avatar and ask about a product. A visitor could request directions. A passenger could ask for information in another language. A shopper could explore products that are not physically stocked in that location. A brand could combine advertising, customer service, entertainment and information within the same physical footprint.
When nobody is interacting with the system, the same display can return to advertising content. This begins to blur the line between media, customer experience and physical interface.
Because those interactions happen digitally, they also create new opportunities for measurement. How many interactions occurred? How long did they last? Which experiences caused people to stop? Which content held people for longest?
The aim is not to reproduce the surveillance-heavy parts of online advertising in the physical world. The more interesting model is simpler: use the physical environment to create attention, then use privacy-conscious analytics to prove that the attention existed.
Digital advertising taught brands to expect data
Advertisers have spent two decades becoming accustomed to dashboards. Once a marketing team can analyse performance by campaign, creative, location and time, it becomes difficult to return to a world where comparatively little immediate campaign information is available.
That does not mean physical advertising should attempt to recreate every feature of online advertising. It should not. Part of OOH's value is that it exists outside the intensely personalised digital environments that can frustrate consumers.
The better opportunity is to combine the strongest characteristic of OOH, genuine presence in the physical world, with one of the strongest characteristics of digital media, the ability to provide evidence of what happened.
Physical presence. Digital intelligence.
That is a more interesting direction than simply putting more conventional screens into more places.
The next generation of OOH will compete for attention, not just space
For much of advertising history, media value has been closely connected to inventory. How large is the billboard? Where is it located? How many people pass it? How often will the campaign appear?
Those questions will continue to matter. But another question is becoming harder to ignore: did anybody actually pay attention?
For physical advertising, that question creates an opportunity rather than a threat. OOH already occupies the real world. It already reaches enormous audiences. The global market is already growing. Digital infrastructure is expanding. Programmatic adoption has significant room to develop. Advertisers are becoming more sophisticated about the difference between a delivered impression and genuine attention.
Those trends are converging.
OOH is growing. OOH is digitising. Advertising is becoming more accountable. Attention is becoming more valuable. Consumers are becoming increasingly accustomed to conventional screens.
The opportunity is a new generation of physical media that can both earn attention and measure it.
At Miirage, that is the future we are building towards. Holographic displays can create experiences that look fundamentally different from the flat screens surrounding us every day. Privacy-conscious audience analytics can then provide evidence of whether those experiences caused people to stop and how long they remained engaged.
The purpose is not simply to create something visually impressive. It is to make real-world attention more useful and more accountable for advertisers.
Because the next evolution of OOH will not be defined by how many screens we can put into the world. There are already enough screens.
It will be defined by which experiences people actually choose to look at, how long those experiences can hold their attention, and whether brands can prove that attention was earned.
Brands need a way to win attention in the real world, and prove it.Further Reading
