Our story


In 2022, the industry came back together IRL at a host of IAB events. Leadership Summit returned to Sopwell House for the first time since 2020 and our flagship conference Engage moved to a new home - The Londoner - with TikTok trainspotting star Francis Bourgeois headlining the agenda. In October, a host of Digital Upfronts shone a light on the latest innovations from the biggest players in the industry, while our first IAB Debrief event celebrated the thriving creativity within the digital ad industry. Meanwhile, we launched The Last Thursday Club - a monthly networking event - to give IAB members a regular opportunity to get together in person.

Our annual full year Digital Adspend report was released in April, showing that investment in the UK digital ad market soared by 41% in 2021 to hit a total of £23.5 billion. The report, which is conducted with PwC, shows that 2021 spend was also up 50% on 2019, the last full year in which the pandemic did not have an impact on activity. Our half-year Adspend update was released in October, showing that spend in the first half of 2022 stood at £12.52 billion - a 15% year-on-year increase on the first half of 2021. 

When it comes to our policy and regulatory affairs work, the Online Advertising Programme (OAP) was a core focus in 2022. We responded to the Government’s initial consultation on the OAP and are continuing to work with our members to ensure industry has a voice in the process. Meanwhile, the Digital Information and Data Protection Bill (DPDI) and online ad ban for HFSS products continued to be priorities - with the Government postponing the latter until 2025.

In September, we launched Gold Standard 2.1 - introducing new criteria to improve end-to-end transparency in the digital advertising supply chain, as well as widening the scope of the Gold Standard to include audio, gaming and CTV for the first time. 

Working with our members, other significant launches in 2022 include: the IAB Sustainability Glossary; our social video series ‘Spill the Tea with the IAB’; our first retail media roundtable; and key definitions relating to CTV


2021 was a year of adjustment for the digital ad industry, but this didn't inhibit its growth or innovation - from record digital ad spend data to new demographics embracing digital. To help advertisers make sense of the UK's changing online habits, we resurrected our Real Living research, the thread running through our Specialism Weeks throughout the year. We hosted weeks dedicated to Audio, Connected TV, Ecommerce and Gaming to explore who is driving growth in these areas, what behaviour looks like and the opportunities for advertisers. This culminated in the release of our Real Living research in full, revealing vital factors advertisers need to consider, from engagement mindsets to the devices people are using today. We also delved further into the world of in-game ads with a Guide to Gaming that explored the opportunities available to brands in this burgeoning sector.

As we trickled back into the office, events IRL were still off the cards. Digital Trust Forum returned for its second year, in a virtual iteration, addressing everything from personalisation in our privacy-first era to protecting young people online and how we can help create lasting solutions. Leadership Summit also went virtual, with Leadership Series bringing leaders together for keynotes and roundtables throughout the year. Speakers included Alastair Campbell, Shazia Ginai and Ruth Davidson on topics ranging from the future of work to climate change. 

Stay Engaged also returned as a series of daily off-stage sessions - think deep-dive interviews and provocative group discussions throughout August. Digital Upfronts was back in October - three weeks where we heard what's next on the scene from some of digital's biggest names and ventured into the future of the world of gaming and podcasts with specialist Upfronts. 

Keeping it virtual, we launched our eLearning platform and made all training complimentary for IAB UK members, spanning regulation, measurement, programmatic and more to help our members stay at the forefront of the latest digital advertising developments. Meanwhile, our weekly podcast had 20,000 downloads in 2021, including episodes chatting to Mindshare about measurement and understanding Nestle’s road to Net Zero. 

Talk of and preparation for a cookie-less future was front of mind across the industry in 2021 as Google extended the cookie deadline to 2023. With a range of alternative solutions under development, our revamped User ID hub gives an overview of what's happening and details solutions from our members.

IAB UK members were also in the spotlight as part of our ID&E in Practice showcase - a collection of standout initiatives spanning different areas of businesses and elements of Inclusion, Diversity and Equity that all help drive greater inclusivity in the industry.

To close the year, our CEO, Jon Mew, reflected on the past ​​12 months with unexpected joys, banished zoom quizzes and hopes for '22.


2020 really was an extraordinary year, with what started as office chatter about a faraway virus turning into a global emergency and a year of social distancing where office workers of the world were asked to work from home. In response, we created IAB UK Connected, which pulls together insights and resources from across the industry to share how all of us had been adapting to the situation.

Before all in person events were cancelled, we managed to host two at the beginning of the year. Our inaugural Digital Trust Forum, which addressed key issues around trust and brand safety and our fourth annual Leadership Summit, which brought leaders together to debate and share ideas - at what turned out to be our last in person event of 2020. During the first lockdown, our flagship event was transformed into Stay Engaged - a series of off-stage audio sessions designed to bring the inspiring speakers of Engage directly to the ears of the industry. A year of virtual events ended with our biggest Digital Upfronts yet, including two weeks of forward-facing sessions, our inaugural Gaming Upfronts and Podcast Upfronts featuring none other than Oprah!

Our research outputs continued for the year and our Adspend figures for 2019 were released as usual, showing the overall online advertising industry was valued at £15.69 billion, before the economic impact of the pandemic was felt. We also released our ‘Powering Up’ research into small businesses and worked with over 30 of our members to adapt this into an interactive online tool for SMEs, to help them unlock more value from digital advertising.

We released our core principles for User ID solutions, setting out the key factors that we believe any viable alternative to third-party cookies needs to meet. We also created our Guide to Digital Innovation, with six chapters taking a future facing look at new tech and market disrupting ideas. Finally, 2020 saw the launch of Gold Standard 2.0 and more advertisers announcing their support for the initiative; plus, our policy work continued apace with December seeing us submit a response to the Government’s consultation on a HFSS online ad ban.


We kicked off the year in Parliament as we jointly hosted an event with Nigel Huddleston MP, highlighting the value digital advertising brings to the UK economy and the social good it brings by enabling free access to news and information to millions.

We continued the year with our inaugural National Anti-Click-Through-Rate-Day, created to gently point out that marketers have become a bunch of ‘clickheads’ by being too reliant on CTR as a metric. We also used this momentous day to launch our Measurement Toolkit full of alternatives, including econometrics and attribution, to the old-fashioned click.

Following on from the townhalls during Leadership Summit in the previous year, we launched our Inclusion, Diversity and Equality agenda. Featuring ‘How to’ guides designed to help employers create an inclusive workplace and boost representation.

In April, as always, we released our Adspend figures for 2018, which showed spend on UK online advertising increasing by 15% year on year to hit £13.44 billion. April 2019 truly was the beginning of the year of mobile as mobile ad spend surpassed desktop for the first time.

We pricked up our ears in May for season two of the IAB podcast, which during its run featured some of adland’s biggest names and racked up over 8,000 listens.

The mid-point of the year brought us back to our flagship event – Engage returned to the Barbican, with star speakers including broadcaster Tina Daheley, author and campaigner Caroline Criado Perez and many more. June also began our work with members and the wider industry to address the concerns raised in the ICO’s Update Report into Adtech and Real Time Bidding.

July brought us a joint research project with Lumen and IPSOS MORI looking into where people were looking and what grabbed their attention the most, from this we produced five rules advertisers should consider to keep attention. Concluding the summer we released our Gold Standard e-learning tool, to educate teams about what the Gold Standard is and how it works. 

Direct to Consumer brands took centre stage in September, as we released our Born Online report which identifies 50 of the leading DTC brands founder profiles, customer basis and business goals. 

The last quarter of the year was no quieter, with Nonference returning to Tobacco Dock for the last time and Podcast Upfronts launching with top talent Jessie Ware and James O’Brien. We also launched our ‘Get into Digital’ guide to help new starters break into the advertising industry.

Finally, as part of our programme to prove the effectiveness of digital advertising we launched a bank of brand case studies, showing how digital has helped brands to grow.


We marked the start of the year with a refreshed brand identity, a new website and a brand new vision focussed on “Building a sustainable future for digital advertising”. This aims to drive the industry to work together to raise standards and ensure digital advertising thrives in the long term.

We also gave our voice a mic, launching episode one of the IAB UK Podcast featuring 40 of the industry’s leading lights to boil down and discuss some of the industry’s big complex issues. The podcast peaked at 3rd in Apple’s Business category and got a 5 score rating in Apple Podcasts.

Engage came early this year, taking place at its spiritual home, The Barbican, in June to a packed audience hearing about authenticity, bravery, and experimentation. Guest speakers included Keith Weed of Unilever, Lucy Jameson of Uncommon London, Tom Goodwin of Zenith, and the inspiring broadcaster and writer Stacey Dooley.

In August we launched “Find your voice” research working with IPSOS MORI to map out the future of voice in terms of technology, consumer expectations and how brands can and should utilise a voice strategy.

We also increased our nationwide presence by launching a Manchester Hub delivering quarterly meetings, presentations and networking events to members.

November saw the launch of a brand new type of event at Tobacco Dock called Nonference. “Don’t take notes, take part” was the rallying cry to get the 800 plus delegates from all levels of industry to learn by doing and try their hand at building blockchain in LEGO and creating their own digital out of home campaign against the clock.

The year saw The IAB Gold Standard grow from strength to strength with over 100 companies certified and registered showing their commitment to reducing fraud, improving the ad experience and increasing brand safety.

Appointing Mind as our chosen charity, we brought the brightest minds in digital together to solve some of the charity’s biggest business challenges through an Ideas Hack.

And finally, IAB UK was recognised as a Carbon Neutral Organisation by the Carbon Footprint Standard having offset our footprint by reducing energy emissions and planting trees in the UK as well as supporting efforts in protecting the Amazon rainforest.


On 5 January 2017, we announced that Jon Mew, former COO at the IAB will take over as CEO from the departing Guy Phillipson. 

Mew also made structural changes to the IAB, hiring James Chandler from Snap. Inc as Chief Marketing Officer, as well as appointing former Chief Strategy Officer, Tim Elkington to the role of Chief Digital Officer and Alex Kozloff to Chief Operating Officer.
