Welcome to the third lesson in our course on AdTech M&A. In our previous discussions, we explored the consolidation trends shaping the open internet's programmatic ecosystem, identifying how the convergence of DSPs and SSPs creates "rationalization" M&A opportunities. You learned that these deals often happen at the single-digit EBITDA multiples that align with your strategic interests.
Today, we shift our focus from the open web to two of the fastest-growing and most disruptive areas in digital advertising: Connected TV (CTV) and Retail Media Networks (RMNs). These channels represent a strategic pivot away from the cookie-based advertising of the past and toward new ecosystems built on first-party data and direct consumer relationships. For you, understanding the M&A dynamics in these emerging battlegrounds is critical for identifying forward-looking acquisition targets that can future-proof your company's position.
The New Frontiers: CTV and Retail Media
While the open web consolidates, CTV and RMNs are experiencing explosive growth. They are not just new channels; they represent a fundamental shift in how media is consumed and monetized.
- Connected TV (CTV): This refers to streaming content via apps on smart TVs and other devices. It combines the high-impact, lean-back experience of traditional television with the data-driven targeting and measurement of digital advertising.
- Retail Media Networks (RMNs): These are advertising platforms operated by retailers (like Amazon, Walmart, or India's Flipkart) that allow brands to buy ads on the retailer's digital properties, leveraging the retailer's invaluable first-party shopper data.
These channels are attracting immense investment, and with it, a wave of strategic M&A. Let's examine each in turn.
Connected TV: The Digital Transformation of Television
The migration of advertising budgets from traditional linear TV to CTV is one of the most significant trends in media. Viewers are moving to streaming services, and ad dollars are following them.
This rapid growth creates a fragmented and complex ecosystem, which is a fertile ground for M&A. The primary drivers for acquisitions in the CTV space are:
- Scale and Reach: Aggregating ad inventory across thousands of different streaming apps and platforms.
- Technology: Acquiring critical infrastructure for ad serving, measurement, attribution, and dynamic ad insertion.
- Data: Gaining access to viewership data to enable better targeting and analytics.
The M&A roundup below provides recent examples of this consolidation in action. Notice how acquirers are buying specific capabilities to strengthen their position in the CTV value chain.

This report from Ciesco highlights key M&A deals in the media and advertising space. It provides concrete examples of the strategic acquisitions being made to win in CTV.
Please review the table titled "M&A Deals 4 CTV, Video & Screens". Pay close attention to the "Rationale" column. You'll see acquisitions aimed at screen-based advertising (T-Mobile/Vistar), location-based targeting (Via Media/Local Factor), and core ad serving infrastructure (Mediaocean/Innovid).
These deals show a clear pattern: companies are buying technology and data assets to simplify the buying process and improve monetization across the burgeoning landscape of digital screens.
Retail Media Networks: The Power of First-Party Data
As third-party cookies disappear, the value of first-party data—information that companies collect directly from their customers—has skyrocketed. No one has more valuable first-party data than retailers, who know exactly what people buy. RMNs are their way of monetizing this asset.
The following video provides an excellent primer on why RMNs have become so powerful.
Retail Media Networks Explained | Retail Dogma
This "Retail Media Networks Explained" video from Retail Dogma clearly lays out the business case for RMNs in a post-cookie world.
First, watch the segment from the beginning, which explains the challenge advertisers face with the decline of third-party cookies. Next, see how RMNs solve this problem from this explanation of how retailers use their first-party data. Finally, focus on the concept of "closed-loop attribution". This is the unique selling proposition of RMNs.
This "closed-loop attribution"—the ability to directly connect an ad view on a retailer's site to a purchase—is the holy grail for advertisers. It provides a level of accountability and ROI measurement that is difficult to achieve in other channels. As a result, the RMN market is booming.
Given your M&A background, the financial implications are clear. Retail media is a high-margin business that can significantly impact a retailer's profitability, making it a core strategic priority and a driver of M&A.
E-Commerce/Retail M&A Trends & Deal Analysis Report 2026 | M&A Insights Blog
This M&A insights report quantifies the growth of retail media and connects it directly to M&A strategy.
Start by reading the section on "Retail media becomes a core P&L engine." Note the forecast for the market to reach $230B by 2028. Next, review the point on how RMNs impact profitability. The mention of 70–90% margins is a key reason this sector is attracting so much investment. Finally, read the section on "Retail-media tech stack consolidation." This highlights the "build/ally/buy" decision facing retailers and signals a key M&A battleground for the underlying technology.
The M&A activity in RMNs often revolves around acquiring the technology to run these networks. Look at the deal table from the Ciesco report again, this time focusing on the RMN examples.

This report also provides excellent examples of RMN-related M&A.
Review the table "M&A Deals 4 Commerce, Retail Media & Shoppable Content". Notice deals like DoorDash acquiring Symbiosys to "Build RMN platform" and Kevel buying Nexta for "Off-site RMN enablement." Crucially for your context, note the deal: Flipkart acquired a majority stake in Pinkvilla for "Commerce-linked media." This is a prime example of a major Indian player making a strategic move in this space.
The Convergence: Walmart Acquires VIZIO
The most powerful trend is the convergence of CTV and Retail Media. The landmark example of this is Walmart's $2.3 billion acquisition of VIZIO, a smart TV manufacturer. This deal perfectly encapsulates the strategic pivot we are discussing.
This was not a retailer buying a hardware company. This was Walmart, which operates one of the world's largest RMNs (Walmart Connect), buying a CTV operating system (VIZIO's SmartCast) to create an end-to-end advertising flywheel.
The "E-Commerce/Retail M&A Trends" report provides an excellent case study on this transaction.
E-Commerce/Retail M&A Trends & Deal Analysis Report 2026 | M&A Insights Blog
This report provides a detailed breakdown of the Walmart/VIZIO transaction, which is a masterclass in modern AdTech M&A strategy.
First, see how the report lists the deal under major consolidators, explicitly stating the rationale was to build its retail media stack. Next, read the detailed case study. Absorb the strategic rationale: "Expand Walmart’s high-margin retail-media inventory and first-party data reach via CTV; integrate commerce signals with CTV ad buying." Note the ~1.35x Price/Sales multiple paid. Finally, read the "Analyst take" at the end of the deal list. The key takeaway is that "Scale + data" strategies like this are winning because they "raise ad/SaaS margins."
By acquiring VIZIO, Walmart can now use its vast repository of shopper data to target ads to VIZIO TV owners. More importantly, it can offer its suppliers (like CPG brands) the ability to track whether a household that saw a TV ad went on to purchase the product in a Walmart store—the ultimate closed loop.
Conclusion
Today we've evaluated the strategic shift toward the high-growth channels of CTV and RMNs. These aren't just niche opportunities; they are reshaping the entire advertising landscape and, consequently, the M&A priorities of major players.
Here are your key takeaways:
- A New Data Paradigm: Both CTV and RMNs are thriving because they offer powerful advertising capabilities in a privacy-first world, built on viewership and purchase data rather than third-party cookies.
- M&A is About Capabilities: Acquisitions in these areas are focused on securing technology (ad stacks, measurement), data, and scale to build integrated, high-margin advertising businesses.
- Convergence is Key: The most sophisticated strategies, exemplified by the Walmart/VIZIO deal, involve converging retail media with CTV to create a powerful "flywheel" that connects media exposure directly to commercial outcomes.
- Opportunity for You: While headline-grabbing deals like Walmart/VIZIO command strategic premiums, the ecosystem of enabling technologies for CTV and RMNs is vast. This is where you might find smaller, high-value technology providers—the "picks and shovels" of this new gold rush—that could fit your target acquisition profile of 3-4x EBITDA.
We have now analyzed the major consolidation trends in both the established programmatic world and these emerging ecosystems. In our next lesson, we will begin to synthesize these insights. We'll move from analyzing the market to defining your specific strategy, starting with how to formulate a strategic M&A mandate to guide your company's global acquisitions.
