How Advertisers Are Navigating the Shift to Addressable TV

Connected TV (CTV), addressable TV advertising, or streaming, whatever the label, the way people watch television has fundamentally changed. Viewers now move fluidly across live, on-demand, and ad-supported experiences, and advertisers are following the audience.

TV is undergoing a structural shift driven by consumer behaviour, with streaming accounting for a growing share of total viewership. Premium live moments—like the Olympics and the World Cup—now span both linear and streaming environments, accelerating this transition.

For advertisers, this evolution creates a meaningful opportunity: bringing data-informed relevance to the biggest screen in the home while maintaining the scale and impact TV has always delivered.

But advertisers must position themselves to keep pace as the channel continues to evolve.

Addressable TV Is Now Core to Modern Media Plans

Connected TV refers to internet-enabled devices that let viewers stream video content directly to the television screen, most commonly, smart TVs and streaming devices or consoles. What once felt incremental is now foundational: streaming is a primary way audiences consume premium video.

According to Nielsen, streaming represents a significant and growing share of total TV viewing in the U.S., continuing to climb as audiences spend more time with ad-supported platforms.

While CTV devices and streaming services have existed for years, today’s landscape looks materially different due to several key shifts:

• Streaming at scale. A large majority of U.S. households now have at least one connected TV device, and ad-supported streaming has become a primary source of premium video reach. For advertisers, this means TV-scale audiences increasingly live beyond traditional linear environments.
• Premium inventory across platforms. Viewers aren’t gathering in one place anymore. Instead, they move across a wide range of streaming destinations, including on-demand programming and live events, expanding reach while increasing planning complexity.
• Evolving audience behaviour. On-demand and ad-supported viewing is now mainstream across generations, reshaping how audiences engage with content and how brands connect with them.
• Programmatic expansion. Programmatic access to CTV inventory continues to grow, enabling more flexible buying and audience-based activation across environments.

Together, these dynamics have moved addressable TV from an emerging capability to a core component of modern media plans—allowing advertisers to apply more precise targeting to one of the most impactful screens in the home.

Connected TV, Connected Outcomes

As viewing has shifted away from a single primetime moment to always-on streaming, CTV now plays a central role in how brands connect with audiences at scale.

According to the IAB, CTV ad spend continues to grow at double-digit rates year over year, driven by demand for premium video environments combined with more precise audience activation. At the same time, the expansion of ad-supported streaming has increased inventory flexibility across platforms.

The opportunity goes beyond incremental reach. Addressable TV connects video exposure to audience signals, enabling coordinated messaging across channels. CTV can work alongside channels such as display, email, and direct mail to deliver more coordinated, relevant experiences that are rooted in audience signals rather than broad demographics.

Advertisers that treat addressable TV as part of a connected, data-informed strategy rather than a standalone video buy are best positioned to unlock its full value.

Fragmentation Demands Orchestration

Execution now determines performance. The complexity of the video ecosystem exposes weaknesses in siloed planning, fragmented identity, and inconsistent measurement.

Key challenges include:

• Budget allocation. Balancing spend across linear, CTV, and digital channels as viewing continues to fragment.
• Platform complexity. Streaming environments vary widely in audience scale, data access, ad formats, and performance.
• Evolving cost dynamics. As linear supply tightens and premium streaming expands, advertisers must evaluate value beyond historical CPM benchmarks.
• Measurement and accountability. The shift toward addressable TV highlights the need for clearer visibility into reach, frequency, and outcomes across environments.
• Market uncertainty. Economic cycles, election years, and global events increase pressure on performance and flexibility.

Navigating these challenges requires more than inventory access. Advertisers need a unified approach to identity, data, and orchestration to ensure addressable TV delivers both scale and measurable impact.

Why Identity Resolution Powers Addressable TV Advertising

As addressable TV matures, advertisers must focus on how data informs activation across a complex video ecosystem.

While CTV advertising is primarily activated at the household level, modern viewing is more nuanced. Multiple individuals with different behaviours and intent often share the same screen, making it increasingly important to understand TV consumption in the context of the broader customer journey.

Advertisers seeing the strongest results focus on a few core principles:

• Use identity-informed intelligence. While activation occurs at the household level, individual-level insights can inform messaging, sequencing, and cross-channel coordination in a privacy-safe way.
• Connect TV to downstream channels. Addressable TV is most effective when aligned with channels such as display, email, and direct mail, where engagement and outcomes can be observed.
• Prioritise outcomes over impressions. Advertisers are increasingly focused on understanding how exposure contributes to real business impact.
• Apply AI to manage complexity. Automation helps reduce fragmentation and deliver more relevant, consistent experiences at scale.

Zeta unifies household-level TV activation with individual-level intelligence across channels. By unboxing the household, advertisers gain clarity into who may be behind the screen, enabling coordinated sequencing, stronger engagement, and measurable outcomes.

The Future of TV Is Identity-Driven

Addressable TV has moved from experimentation to expectation. Streaming scale is here. Fragmentation is increasing. Performance pressure is not going away.

Advertisers that rely solely on household-level reach will struggle to connect exposure to outcomes. Those that combine TV activation with individual-level intelligence across channels will drive stronger coordination, clearer measurement, and measurable growth.

Zeta helps brands move beyond impression-based buying and into identity-powered orchestration across the customer journey.
