Connected television advertising has emerged as one of the most dynamic and rapidly growing segments of the global AdTech market. As streaming platforms have scaled globally and linear television viewership has continued its long-term structural decline, the advertising technology infrastructure built to serve the connected television environment has become a major driver of overall AdTech market growth. For the late 2020s, CTV advertising is expected to remain one of the primary growth catalysts as the AdTech market tracks toward $1.26 trillion by 2030.
The CTV Advertising Landscape in 2026
Connected television advertising encompasses advertising served within streaming applications viewed on internet-connected television sets and streaming devices. The category includes advertising on subscription video on demand (SVOD) platforms that have introduced advertising-supported tiers — Netflix, Disney+, Max, Amazon Prime Video, and Peacock — as well as advertising-supported video on demand (AVOD) platforms that are free to consumers, including Pluto TV, Tubi, and Peacock’s free tier, and free ad-supported streaming television (FAST) channels.
The CTV advertising market has expanded substantially as major streaming platforms have launched and scaled advertising-supported offerings. Netflix’s advertising tier, launched in late 2022, had accumulated tens of millions of subscribers within its first year. Disney+ and Max made similar moves, driven by the need to find revenue models that could support the economics of premium content production without relying exclusively on subscription fees. The result has been a substantial expansion of available CTV advertising inventory, creating new opportunities for the AdTech infrastructure built to serve that inventory.
Why CTV Is a Distinct AdTech Challenge
Connected television advertising requires a different set of AdTech capabilities than the open web display and mobile advertising that has dominated programmatic infrastructure for the past decade. Several characteristics of the CTV environment create distinct technical requirements.
Identity in the CTV environment cannot rely on browser cookies, which do not exist in streaming applications. Instead, CTV targeting relies on IP addresses, device identifiers, and household-level identity graphs built from deterministic matching of known user data. This has created demand for identity resolution technology adapted to the living room environment, and has accelerated investment in household graph data and probabilistic identity modelling.
Measurement in CTV is also distinct from web-based advertising measurement. Viewability, as understood in the display advertising context, has a different meaning when the screen is a television viewed from across the room. Industry bodies including the IAB Tech Lab and the MRC have developed CTV-specific measurement standards, and the AdTech industry has invested in third-party verification capabilities adapted to the streaming environment. Attribution — connecting CTV advertising exposure to downstream business outcomes — requires different methodologies than last-click or multi-touch attribution models built for web environments.
The Programmatic CTV Market
Programmatic buying has extended into CTV, though the dynamics are different from the open web programmatic environment. Private marketplace deals and programmatic guaranteed transactions are more common in CTV than the open auction environments that dominate web display, reflecting streaming platforms’ desire to maintain more control over buyer access and pricing. The major streaming platforms have built out their own programmatic infrastructure, while also enabling access through independent DSPs and ad marketplaces.
The Trade Desk has been a prominent beneficiary of CTV advertising growth, as advertisers seek independent programmatic access to CTV inventory that allows them to buy across multiple streaming platforms through a single interface. The competition between platform-native advertising systems and independent buy-side platforms for CTV advertising budgets is one of the defining competitive dynamics of the current AdTech landscape.
CTV and Audience Data: The First-Party Advantage
One of the most significant characteristics of streaming platforms as advertising vehicles is the richness of the first-party audience data they possess. Streaming platforms know what their subscribers watch, how long they engage, what they search for, and — in many cases — demographic and household information collected at account registration. This first-party data provides a basis for audience targeting that is substantially more accurate than the third-party data-dependent targeting of the open web programmatic ecosystem.
This data advantage is one of the reasons CTV advertising has attracted premium CPMs compared with display advertising, and why streaming platforms have been able to build advertising businesses that command meaningful revenue alongside their subscription revenues. It also positions CTV as a beneficiary of the broader industry shift away from third-party data, as the programmatic ecosystem seeks alternatives to cookie-based targeting.
Brand Safety and Context in CTV
Brand safety considerations in CTV differ substantially from those in the open web environment. Streaming platforms operate within known content environments — professionally produced television and film content — that carry relatively low brand safety risk compared with the user-generated content and open web inventory that has been a persistent brand safety concern in display advertising. This characteristic has made CTV advertising attractive to brand advertisers who have historically been cautious about programmatic buying in open web environments.
The premium content environment of major streaming platforms, combined with the household screen context of television viewing, aligns well with the brand-building objectives of major advertisers. This alignment has driven sustained investment from brand advertisers who have extended their television advertising strategies into connected television, treating CTV as the digital extension of their broadcast and cable television buying.
The Growth Trajectory for CTV AdTech
CTV advertising spending is growing at rates substantially above the overall AdTech market’s 9.8% annual pace. Estimates from Magna Global, eMarketer, and other advertising forecasters project CTV advertising spending to reach $50 to $60 billion globally by 2028, with associated AdTech infrastructure growing in proportion. The technology layers required to serve CTV advertising — ad serving, targeting, measurement, verification, and yield management — represent a substantial and fast-growing component of overall AdTech investment.
For organisations across the advertising ecosystem — brand advertisers, media agencies, streaming platforms, and AdTech providers — the CTV opportunity is one of the defining strategic priorities of the late 2020s. The infrastructure being built today to serve the connected television advertising market will determine competitive positions in one of the fastest-growing segments of the global media economy.
