At IAB’s Annual Leadership Meeting (ALM) this year, the organization marked its 30th anniversary – a milestone that lands awkwardly in the middle of a fresh identity crisis for the business it helped build.
Because yes, the banner ad really did become programmatic. Then it became mobile. Then social. Then video. Then ‘outcomes.’ And now we’re staring down an era where AI can generate the content, optimize the targeting, buy the media and write the post-campaign report, all before anyone’s even worked out what, exactly, we’re measuring.
And yet, in a room full of people whose job titles have evolved faster than their LinkedIn photos, one thing kept popping up: the IAB’s most important product isn’t a deck, a committee or even a conference. It’s the boring stuff. The standards. The definitions. The measurement frameworks. The shared language that stops a market from collapsing into a thousand incompatible ‘trust me, bro’ claims.
To mark the anniversary, The Drum spoke with some of those who’ve seen the whole arc up close, from dial-up chaos to the present day: Rich LeFurgy, the IAB’s founding chair; Wenda Harris Millard, a past chair who remembers just how naïve (and hilarious) those early years were; Scott Cunningham, who helped push the industry into its more technical, standards-led era; and Peter Naylor, who chaired the IAB in 2012 and watched wave after wave of ‘the next big thing’ hit the shore.
We also heard from IAB CEO David Cohen about what 30 years of compounding growth looks like and why, in an AI moment, the industry may need the IAB’s ‘big tent’ approach more than ever.
Start with LeFurgy and you quickly remember, this wasn’t inevitable. He traces the origin story back to something almost quaint – a trade publication editorial that basically said, this new ‘internet media’ thing needs a trade association. “It sparked an idea with me that I really thought we needed a trade association to establish the credibility of the medium,” he tells The Drum.
In April 1996, about 36 people gathered in San Francisco to map out what the thing should be and, crucially, to model it against the grown-up media associations of the day. Because, as LeFurgy puts it, the early internet wasn’t just messy, it was “absolute chaos in the wild, wild west.”
The credibility problem was existential. There were “outrageous claims… ahead of their time,” he says – the kind of lines we still hear in 2026, delivered with slightly better fonts. Agencies, understandably, weren’t buying it. They had a “wake me when it’s over” attitude.
So the IAB did something that seems obvious now and was radical then: it tried to prove the market existed.
“We partnered with PricewaterhouseCoopers to do an audit of actual spending in the fall of 1996… to show that spending was real and to provide air cover for our salespeople,” LeFurgy says.
The “sticker,” he recalls, was $276m in Q4 1996. Cohen, on stage at ALM, put the punchline bluntly: in 2024, the number was roughly $260bn – and the IAB has grown double digits for most of its 30-year run.
If that sounds like destiny, Wenda Harris Millard is here to remind you it was also… absurd. She remembers being in San Francisco in the very early days, trying to find an office, panicking about being late and calling back to New York for the “address.” The response: “OK, it’s w, w, w.”
“The reason we lived in this crazy bubble… it’s the only thing this young girl knew was when we said address,” Harris Millard says.
That’s the real point of the nostalgia: the industry didn’t just lack tools, it lacked basic shared assumptions. Which is why the IAB’s early focus on standards and measurement wasn’t admin. It was survival.
The rails: standards, measurement and the right to trade
If you want the IAB’s core value in one sentence, Peter Naylor offers it: the IAB helped make digital “as easy to buy and easy to sell as possible.” And that “easy” was hard-earned.
Harris Millard frames it as a practical necessity: “We had to focus on a lot of the standards that didn’t exist… trying to figure out the rules everybody should be trying to play by and you need some kind of a governing body for that to happen.”
Her warning is still current: “The worst thing that can happen is that individual companies run off and decide what their standards… should be… That just creates even more chaos.”
She points to measurement as a defining contribution: “The IAB took a lead role in measurement, because we promised marketers that this would be a very accountable medium.”
LeFurgy is even more explicit about what standards did in those early banner years: they reduced friction. And friction in a market trying to convince Madison Avenue it’s real is fatal.
“There was a lot of friction in the marketplace,” he says. Without standards, “700 different banner sizes” meant teams obsessed with technical negotiation rather than “creating great advertising and great media plans.”
That line matters because it’s the throughline to today: the format has changed, but the role of standards hasn’t. The glamorous world of banner sizes has simply been replaced by the even more glamorous world of AI governance, interoperability, data rights and “what counts as an impression when nobody’s looking at a screen.”
Acceleration: waves keep coming and you don’t get to stop the ocean
Naylor’s mental model of digital isn’t a timeline; it’s a coastline. “There’s been wave after wave of big innovation. We started with banners and buttons and then search and then social media. AI is obviously here right now and all in between is the rise of commerce and the rise of video,” he says.
When he wants an example, he goes straight to the moment TV began to understand the internet wasn’t just “promo.” Disney putting full episodes online triggered a chain reaction – NBC, then Hulu, then OTT becoming “streaming” as default.
His point isn’t just that things change. It’s that the IAB’s job is to stop every new wave from splintering the market into incompatible definitions.
Because digital isn’t a single channel but, in actual fact, infrastructure. It leaks into everything: retail, entertainment, publishing, commerce, creators, the open web, the walled gardens and, now, generative systems that might not need ‘websites’ in the way the last 30 years assumed.
Transformation: from ‘midnight banner swaps’ to AI-era compliance
Scott Cunningham’s origin story is the perfect antidote to any tendency to mythologize those early years. “Way back when, I was the guy who was at the bar on Saturday night and who had to leave at midnight to stumble into the office to change out the whole front of the website so that we had a new banner ad,” he says.
Then, someone arrived with an ad server. “I said, ‘I love you. This is great. Now I don’t have to leave the bar any more on the weekends.’”
That’s not just a funny story. It’s a snapshot of what “professionalizing the industry” actually meant: moving from human duct tape to systems, protocols and repeatability.
Cunningham later helped found the IAB Tech Lab in 2014 and today he’s focused on quality assurance and compliance because, in the AI era, ‘trust’ isn’t a slogan. It’s a requirement for the market to function.
“I joined [AAM] to help the industry put together a lot of good quality assurance programs moving forward,” he says, “because I do believe that compliance is where we need to take things.”
LeFurgy thinks the current AI disruption will be as significant as the dotcom era, but with a key difference: we’re not starting from zero any more and everyone knows enough to be scared.
Which is why his prescription sounds familiar: “Coming together as an industry so that we can create a standard so that everybody’s running on the same rails [and] we do the best thing for the consumer.”
30 years of compounding and the next job for the IAB
Cohen’s anniversary framing was simple: the IAB has been at the centre of every major inflection point because it keeps doing the same thing, over and over, in new contexts – convene, define, standardize, measure, repeat.
The shift now is that the next inflection point isn’t just a new channel. It’s a new actor in the system: AI that can create, distribute and monetize at machine speed while simultaneously raising questions about scraping, rights, provenance and what it even means to ‘trade’ attention.
Meanwhile, retail media is charging in as the newest ‘wave’ and, if the last 30 years taught the industry anything, it’s that retail doesn’t get to invent its own physics. It will need shared definitions, shared standards and shared measurement, or it’ll recreate the chaos that banners had to climb out of.
30 years on, the IAB’s achievement is not that it predicted the future, it’s that it built the plumbing that let the industry survive its own imagination.
Or, to borrow the vibe of those early meetings that LeFurgy described, digital grew up because somebody, at some point, decided the boring work mattered enough to organize around it.
