From Expansion to Consolidation: Mergers, Bundles, and the Impact on Advertisers
Over the past decade, the streaming ecosystem has shifted from a handful of early players to a sprawling landscape of F.A.S.T. (Free Ad-Supported TV), Subscription Video On Demand (SVOD), and hybrid models. Once dominated by explosion and innovation, the market is now entering a phase of consolidation, strategic partnerships, and bundling, as major players seek scale, content libraries, and long-term profitability.
For advertisers, this continues the challenge of understanding how and where they can most efficiently reach their target audiences as the landscape continues to shift from one of expansion to consolidation. It will be important to clearly understand access to inventory, ownership, and platform overlaps to effectively plan your advertising spend.
Recent Mergers and Acquisitions
Netflix & Warner Bros:
In Q4 of 2025 Netflix announced that it had to agreed to buy Warner Bros. This deal includes Warner Bros’ film and television studios and streamer HBO Max. This transaction would give Netflix access to content like HBO series “Game of Thrones” and “The Sopranos”, franchises including Batman, Superman, Wonder Woman, and Harry Potter, and classics such as “Casablanca”.
As to what will happen to HBO Max if the Netflix deal goes through, it is still up in the air. As of now Netflix has shared that both services will continue to operate separately and no content is changing until the transaction is officially closed. This is one to keep an eye on as the transaction closes to see if Netflix decides to maintain two separate streaming platforms in hopes of driving increase crossover subscribers or if they combine the two services. Another thing to keep an eye on is where content lands as that can affect subscribers and the makeup of the audience. If you have already laid in your campaigns for either or both of these platforms don’t forget to check-in to see how changes may affect your buys.
[As of December 22nd, 2025 - Paramount, who recently closed a $8 billion merger with Skydance, is moving forward with its hostile $77.9 billion bid for full takeover of Warner Bros. which includes networks like CNN.
Paramount is one of Hollywood’s remaining legacy studios. Additional to its traditional film and TV production, it owns streaming service Paramount+, networks like CBS, MTV, and Nickelodeon.]
Disney+, Hulu, and ESPN:
While this acquisition happened prior to this year, the company still continues to merge the 3 brands together with Disney CEO Bob Iger announcing during the Q3 earnings call that Hulu and Disney+ will become a single standalone app. As for the fate of Hulu it is a bit unclear. As of now, Disney has plans to eventually eliminate the standalone Hulu app, but there is no set timeline and as of December 2026 consumers can still subscribe to Hulu standalone. In 2026, Hulu content will be folded into the combined Hulu and Disney+ app. As content across these platforms continue to change its important to keep an eye on your media buys to understand what inventory you are purchasing so you do not accidentally double purchase the same or end up with a blend across the full portfolio when you are only wanting a specific set of inventory.
Why this matters to advertisers
As the streaming landscape continues to consolidate, it is increasingly important for advertisers to understand exactly where their inventory is running and who ultimately owns it. Platform ownership is not always obvious, and depending on the buying path or partner, access to specific inventory can vary. What may appear to be separate services or apps can, in reality, be part of the same parent company or ad ecosystem, which can impact everything from audience reach to measurement and reporting.
At the same time, the rise of bundling and mergers means inventory is often packaged together across multiple properties. While this can create efficiencies, it also introduces the risk of unintentionally double-purchasing the same audience or inventory across what are perceived as distinct platforms. For advertisers trying to reach a very specific audience aligned with one service, buys may now include additional properties that do not match the intended strategy, diluting performance or inflating frequency.
In a period of constant change, clarity is critical. Advertisers and agencies need to ask more detailed questions about what inventory is included in a buy, how audiences are defined and deduplicated, and how platform changes may impact campaigns already in market. Taking the time to fully understand these details helps protect budgets, improve efficiency, and ensure media investments are aligned with both targeting goals and business outcomes.
What Advertisers Should Do Next
As streaming platforms consolidate and bundle, advertisers must look beyond platform names to understand true inventory ownership, audience overlap, and how buys are packaged. Asking the right questions and monitoring changes closely helps avoid wasted spend, protects targeting precision, and ensures media dollars are working as efficiently as possible. As you review and finalize 2026 plans, it is especially important to check in on any campaigns already placed to understand whether platform changes could impact performance. Ongoing reporting reviews throughout the year can also help identify shifts in results tied to evolving inventory and audience composition.
If navigating these changes feels overwhelming, it doesn’t have to be. An agency that is well versed in the streaming landscape can help simplify the process. Partners with deep experience and established relationships across both direct platform buys and streaming aggregators are best positioned to understand how mergers affect inventory access, targeting, and measurement. A partner like Avail Media, can help advertisers stay ahead of changes and make confident, informed decisions.
