To succeed in digital advertising, advertisers and publishers need to master the art of working within—and beyond—the boundaries of Walled Gardens. It’s not rocket science; success comes down to crafting a strategic digital game plan and executing it well.
The big three Walled Gardens—Google, Meta, and Amazon—consume a significant portion of the digital ad revenue pie. But what exactly are Walled Gardens, how do they shape the advertising world, and where do independent adtech players like Next Millennium fit into the equation? In this guide, we’ll explore:

In the world of digital advertising, a Walled Garden is a closed platform where the provider maintains complete control over every aspect of the advertising ecosystem.
Independent adtech organizations—like ad networks, ad exchanges, SSPs (Supply-Side Platforms), DSPs (Demand-Side Platforms), and ad servers—fill the gaps by offering more customization and flexibility. These alternatives are ideal for advertisers needing unique data sets or specialized targeting, even if they don’t match the scale of the big players.
The concept of Walled Gardens has deep roots, dating back to the 1970s in the telecommunications industry. John Malone, founder of Telecommunications, Inc. (later acquired by AT&T), coined the term to describe telecom companies’ ownership of everything transmitted via their networks. Fast forward to the digital age, and the idea was adopted by major tech companies as they began to dominate their ecosystems. Apple, for example, created its iOS environment—a seamless yet closed loop of devices, apps, and marketplaces.
The power of modern Walled Gardens truly emerged when privacy regulations like GDPR came into play. With third-party cookies on the decline, companies like Google, Facebook, and Amazon doubled down on their first-party data, creating secure, closed environments for targeted advertising. While this move safeguarded user privacy and complied with new laws, it also excluded independent ad tech companies from accessing the data goldmine, forcing them to innovate new ways to connect advertisers and publishers effectively.
By understanding Walled Gardens and their limitations, advertisers can navigate these ecosystems while exploring open alternatives to optimize their campaigns. Knowledge is power, and knowing the difference between ad networks and ad exchanges is a great way to supercharge your digital advertising strategy.
The big three Walled Gardens—Google, Meta, and Amazon—consume a significant portion of the digital ad revenue pie. These platforms thrive on vast amounts of behavioral, search, and purchase data collected from their billions of users. This environment of first-party data creates an intensely rich, enticing lure for advertisers to target audiences with precision. Let’s break it down:
That’s a lot of juicy user data wrapped up in these exclusive ecosystems! The sheer scale and depth of these Walled Gardens make them incredibly powerful tools for advertisers, but navigating them requires a strategic approach to make the most of their opportunities while understanding their limitations.

However, the closed structure of Walled Gardens isn’t without drawbacks. Advertisers and publishers face restrictions on data access, limited reporting, fewer ad format options, and challenges with broader targeting. These limitations can stifle creativity, innovation, and competition, making it harder to stand out in a saturated market.
If you’re feeling boxed in by Walled Gardens, programmatic advertising offers a compelling alternative.
Programmatic advertising automates the buying and placement of ads, leveraging technology and real-time data to reach users more effectively. It pulls from multiple data sources—such as mobile usage, social media interactions, and browsing habits—to tailor ads to user profiles dynamically.
Unlike Walled Gardens, programmatic advertising operates on a network of open ad exchanges and independent platforms. This means advertisers gain access to a broader array of ad inventory across multiple publishers, enabling greater flexibility and customization. Beyond simple demographics, programmatic ads use insights like purchase history and device behavior to create highly targeted campaigns.
