Chris Espey is a digital media and advertising technology professional with experience across publishers, programmatic media, marketing platforms, enterprise technology and commercial growth.
This site shares perspectives on the evolution of advertising, platforms, data and marketing technology — with advisory services available for selected projects.
Chris’s career has followed the major shifts in digital advertising and marketing technology — from early digital media sales and publisher monetisation, through the rise of programmatic, the growth of marketing platforms, and today’s expansion of retail media, CTV, data-driven advertising and AI-enabled platforms.
This experience provides a practical view of how the advertising market has evolved, how platform businesses are reshaping media investment, and where commercial opportunities are emerging.
The advertising industry is undergoing a fundamental shift.
Platform ecosystems are expanding beyond their core products into advertising. Retail media is reshaping commerce. Connected TV is redefining video. Customer data platforms are becoming central to marketing infrastructure. And AI is accelerating how campaigns are planned, created, and optimised.
Having worked across publishers, adtech, and marketing platforms, this perspective is shaped by the full evolution of digital media — from early display and direct sales through to programmatic, data-driven marketing, and platform ecosystems.
Five areas shaping the modern advertising and marketing landscape.
The evolution of programmatic into platform-driven ecosystems across DSPs, retail media, and walled gardens.
Programmatic has moved well beyond open-exchange RTB. Today's landscape is shaped by walled gardens, identity fragmentation, supply path optimisation, and the increasing weight of platform-owned demand. Understanding how these layers interact is central to modern media strategy.
The rapid growth of commerce-led media networks and their role in performance marketing.
Retail media is now one of the fastest-growing channels globally. Commerce platforms — from Amazon to grocers, marketplaces, and ride-sharing — are leveraging first-party transaction data to build genuinely differentiated advertising propositions.
The shift from traditional broadcast to streaming and the implications for advertisers.
CTV is restructuring how video is bought, measured, and valued. Streaming has compressed the gap between brand and performance media, while reshaping inventory, frequency, and attribution models.
The role of CDPs, measurement frameworks, and data-driven marketing infrastructure.
Marketing technology is moving from a tooling discussion to an infrastructure one. CDPs, identity, consent, and measurement frameworks are now strategic decisions that shape what's possible in media and customer experience.
How AI is transforming creative, media buying, and marketing workflows.
AI is meaningfully changing parts of the marketing stack — creative production, audience modelling, planning, and optimisation. The interesting question is where it shifts the operating model versus where it simply automates existing workflows.
Display, publisher partnerships, and direct insertion-order media.
Real-time bidding, exchanges, DSPs, and the maturing of the supply chain.
Customer data, identity, and marketing platforms moving to the centre of strategy.
Walled gardens, commerce networks, and platform-led advertising models.
Generative tooling and automation reshaping creative, planning, and optimisation.
Retail media is often described as shopper marketing with better data, but the shift is bigger than that. It is changing how brands connect media investment to commerce outcomes.
Advertising is becoming a major revenue opportunity for platform businesses with audiences, data and transactions. The challenge is building an ad business that creates value without damaging the customer experience.
Programmatic advertising has evolved from automated buying into core media infrastructure. The next opportunity is a stronger commercial narrative around quality, data, measurement and value.
