Our Monthly Round-up of the key pieces for October includes: – five articles (curated for you), a Podcast, Media & AI section, the Work – & our usual Back to Henley chapter.
This is a Special Edition of ‘Our Monthly Review’ as we have included Six Observations from the Adforum London Summit, held 19-23rd October. We saw 21 agencies – with 38 worldwide consultants – over 4 days.
Our October highlights:
1. Our top pick for this month, we had to pick this opening growth piece from Mckinsey & Co, the report looks at the investment Marketers have made in mar-tech from cost centre to growth engine. We know we are seeing the Third Revolution in media after commercial tv and digitalisation. Marketers feel that mar-tech isn’t dead, it is just drowning in its’ own complexity. AI is giving leaders the chance for a “re-do” so marketing technology can finally realize its potential.

2. Secondly, a piece from Andrew Tindall. The most significant digital marketing finding of the past decade. Creators are brand-builders, not salesmen. At the IPA (Institute of Practitioners in Advertising) conference Jane Christian shared the first-ever creator econometric database. Analysing the returns of 220 creator campaigns globally, they’ve found that creators have the highest long-term ROI of any other channel.

3. Thirdly, on the turnround of M&S – back in 2018 customers were saying 3 things about Marks & Sparks: too expensive, not for me, and not real food. Archie Norman’s focus has been an amazing turnaround to firstly listen to customers – ‘be closer to the customer & closer to colleagues’. The insight team has done a fantastic job on focusing on customer centricity and the success shows just what can be done with a great leader.

4. Fourthly, we’ve become a fan of the Creative Salon, so we have picked this piece on John Lewis’s Rosie Hanley, before we see any Christmas ads John Lewis is winning already. Speaking at Advertising Week Europe earlier this year, Hanley explained that the return of ‘Never Knowingly Undersold’ was no nostalgic indulgence, but a strategic move backed by data. As they move into their ‘golden quarter’ have they cracked it once again.

5. Fifthly, we have chosen this piece from Michael Farmer’s substack, last month he produced a piece on how AI would decimate agency pricing. This piece focusses on agencies and ‘how did it all go wrong’. Within the next month – the network that won Cannes Network of the Year in 2025 may disappear altogether.

Podcast: An excellent WARC podcast this month, on ad agency strategists – and what’s next, it features the super-smart Tom Morton, and it’s a great listen.https://podcasts.apple.com/gb/podcast/ad-agency-strategists-face-a-turning-point-whats-next/id1563243327?i=1000730537177
Media: An interesting episode of Mediasnack: The Love Boat Episode: Inside the Breakup and Hookups of Major Agencies, which describes the ‘bold bets in the Red Ocean’. https://www.youtube.com/watch?v=TPGljhOsMyA
AI: A report from Google on AI ROI. Companies that were quick to adopt AI agents are seeing real returns. They’re using agents to improve customer experiences, free up employees for smarter work, and give departments like marketing, IT, and HR a productivity boost. This ROI helps justify bigger investments and get leadership on board for a broader AI scaling strategy. https://services.google.com/fh/files/misc/google_cloud_roi_of_ai_2025.pdf
Time for the Work: Congrats this month to McDonald’s & Leo Burnett Uk for their latest tv work – the McDonald’s World Menu heist. https://www.adforum.com/creative-work/ad/player/34725925/world-menu-heist/mcdonalds
Back to Henley: Our fortnightly feature in the Henley Standard continues where we interview local entrepreneurs. It’s called Let’s Get Down to Business. We were delighted this month to interview Tim Davies, Founder of DuelFuel® https://www.henleystandard.co.uk/news/henley-on-thames/499230/snack-creator-who-helps-exercise-and-recovery.html
Six Observations from the Adforum London Summit:
![]()
1. Pivotal Inflection Point: Whilst the marketing world remains cautiously optimistic, agencies are waiting the outcome of the Omnicom/IPG merger. Once announced there will be a cacophony of change reshaping the marketing industry. The three biggest holding companies will restructure around ‘defined crafts’ & business enterprise services – unifying methodologies & improving efficiencies. The operating systems will integrate capabilities across media, creative, CRM, and more, enabling connected networks to be faster with cheaper delivery. The three dominant mega-holding companies (with an estimated 60% of revenue coming from the media discipline) will drive growth and change – at the intersection of technology and marketing before other mergers are announced.
2. Economic Uncertainty: The underlying economic uncertainty in the UK is affecting clients and agencies alike – and that uncertainty also stems from global issues that are in play currently. Clients are sometimes deferring expenditure to 2026 rather than pressing the spend button in the last quarter of 2025. This behaviour has been happening for a few months already and is likely to continue until Q2 in 2026. Clients who may have pitched their accounts are appointing agencies but pausing any work until then.
3. Indies: Independent agencies (and to an extent technology companies) will continue to win clients where they can excel in creativity, strategy, and/or innovation. As in other markets we are seeing a proliferation of agency start-ups, team chemistry (i.e. have you worked together before) and the defining stature of the opening client remain key to success.
4. Media & Integrated Pitches: The third media revolution is underway, AI democratizes technology but also risks homogenizing brands by converging marketing efforts toward category averages ( a “race to the mean”). AI is normative by nature and that AI is compounding by nature – meaning brands that do not differentiate risk becoming bland with less empathy. AI is levelling the technological playing field, eroding and disrupting traditional revenue streams like translation and account management, pushing agencies to adopt technology rapidly. The fee-for-service (FTE) model disincentivizes technology adoption due to reliance on human hours. Clients are adopting models where media and creative collaborate from the outset, breaking down silos and enabling real-time campaign evolution based on data – we are seeing a 25% growth in Integrated Pitches.
5. Data & Tech: Data is now more critical than technology alone. Agencies are leveraging proprietary first-party data combined with large data assets to enrich media buys, enabling more effective, targeted campaigns. This shift is driving a blurring of traditional buy-side and sell-side roles, with agencies increasingly engaging in principal buying and direct publisher deals to enhance margins and client outcomes.
6. Social Platform: The use of social media, influencers and social content is now a central part of many campaigns and has seen significant growth in the last few years. This has in turn enabled agencies to develop strong propositions for clients. Such specialist agencies are totally social focused with multiple work and income streams as a result. The ‘Social Platform’ has become a far more serious communication strategy which can deliver strong and measurable results not only in performance but in brand building which will support the more traditional big brand ideas in above line media.
In Summary: The industry stands at an inflection point at the intersection of AI-enabled efficiency and human-led differentiation. It is undergoing accelerated reinvention driven by integration, AI, data, social and new commercial models. Agencies that blend data, creativity, and emotional intelligence – and prove commercial impact through new remuneration models – will define the next era of marketing growth.
For Marketeers, we can set up a 30 minute Teams/Zoom call on the Adforum Summit in London for you, or your wider leadership team, where we expand on the points above.
If you’d like to discuss how these insights can apply to your organisation, we’d love to re-connect.
Kind regards
