An independent voice
in audience research
Audience measurement specialist with over two decades of experience across the UK media industry.
Making media measurement work for everyone
"Measurement only has value if people understand what they're measuring — and trust it."
My Story
I’m Joe Lewis, an independent audience measurement consultant with over 20 years of experience at the heart of the UK media industry.
My career has been built on one consistent question: how do we know who is actually watching, listening, reading — and can we trust the numbers that tell us? It’s a question that has only grown harder to answer as media consumption has fragmented across an ever-expanding range of platforms, devices and formats.
I’ve spent those two decades working with media owners, agencies, advertisers and industry bodies to make sense of the data they use every day — helping them understand what it measures, where it falls short, and how to get more from it.
Beginning my career as a government statistician, I’ve subsequently held a number of senior roles across measurement vendors, such as GfK and the Nielsen/Fifty5Blue joint venture “AGB Nielsen”, as well as at Barb.
Today I work across the industry for multiple clients, including acting in a fractional role as Chief Research Officer at Origin, the UK’s advertiser-led cross-media measurement service, governed by ISBA and backed by the World Federation of Advertisers. Origin is the UK’s most ambitious attempt to solve the cross-media measurement challenge, building a single, independent currency that allows advertisers to understand their deduplicated reach and frequency across all media channels. I lead the research methodology and data quality work that underpins it.
Why Independent Consultancy?
The best advice in measurement is independent advice. I have no commercial stake in any particular measurement solution, platform or vendor — which means the guidance I give is always centred on what’s right for the client, not what serves any commercial relationship.
The measurement landscape has never been more complex ,or more consequential. With billions of pounds of media investment riding on the accuracy of audience data, getting measurement right matters. My job is to help organisations navigate that complexity with clarity and confidence.
Alongside my role at Origin, I am available for independent consultancy engagements, training programmes, research projects and speaking appearances. All independent work is undertaken separately from my Origin responsibilities.
What I Bring
Over two decades in the industry has given me a perspective that spans the full measurement ecosystem, from the technical architecture of panel-based measurement to the practical realities of how data is used in planning and buying. I’ve been involved in JIC evaluations, cross-media methodology development, large-scale audience studies and industry working groups.
I work with clients across the spectrum: media owners trying to demonstrate the value of their audiences, agencies navigating incompatible data sources, advertisers frustrated by the gaps in cross-media reporting, platforms seeking credible independent measurement, and industry bodies designing the frameworks that underpin it all. My approach is practical, evidence-based and I hope, clear. Good measurement advice doesn’t need to be complicated.
