What is CTV and how is it transforming the Future of Advertising

Television has entered a new era, with Connected TV (CTV) now at its centre. What began as an alternative to traditional broadcast viewing has evolved into the primary way audiences consume shows, movies, and live events. With 88% of U.S. households owning at least one internet-enabled TV device according to Statista, CTV has become one of the most influential channels in modern advertising.[1] By delivering video ads seamlessly across smart TVs, gaming consoles, and streaming devices such as Apple TV, Amazon Fire TV Stick, and Roku, CTV combines television’s visual impact with the precision of digital advertising. As content is delivered digitally, advertisers can use data signals to reach households based on specific interests, behaviours, lifestyles, or demographics, avoiding wasted spend on irrelevant audiences. This shift toward relevance makes campaigns more efficient, stretches budgets further, and drives higher returns on investment. At the same time, CTV ads appear alongside premium, high-quality streaming content, offering brands a more controlled and trustworthy environment than the open web.
 
Traditional television has always struggled to provide detailed reporting, but CTV offers a level of insight that marketers are more familiar with from digital advertising. As such, advertisers can see how many people watched an entire ad, how often they saw it, and even whether they later visited a website or app on another device. This level of transparency allows for real-time optimisation, helping brands refine their campaigns as they run rather than relying on assumptions or post-campaign summaries. The ability to track metrics, such as completion rates and cost per completed view, provides a clearer picture of campaign effectiveness, with many streaming services reporting completion rates exceeding 90% due to non-skippable ad formats.[2]
 
Accessibility for all businesses
 
As CTV has become more accessible, it has opened the channel to businesses of all sizes, shifting it away from a space once dominated by large national brands. With many platforms offering lower entry points, flexible spending options, and self-service tools that reduce reliance on agency partnerships, local and regional advertisers can now test new markets, monitor performance through intuitive dashboards, and scale their efforts based on real results rather than upfront commitments. As a result, the broader advertising landscape is changing rapidly, and streaming has become the default viewing method for many households.
 
This shift in behaviour means advertisers can no longer rely solely on linear television to maintain reach. CTV fills the gaps created by declining broadcast viewership, allowing brands to connect with audiences who have drifted away from scheduled programming. This is especially effective for connecting with cord-cutters and streaming-first viewers who spend less time on social media or traditional television, enabling brands to reach audiences often missed by other channels.
 
At the same time, programmatic buying has become central to how CTV campaigns are delivered. Rather than negotiating fixed time slots months in advance, marketers can now purchase impressions dynamically. Due to this, their ads appear to the right viewers at the right moments. This automated approach optimises both pricing and placement, making campaigns more responsive to audience behaviour and market conditions. As television and digital media converge, advertisers reshape long-held ideas about how television advertising works. CTV brings the emotional impact of large-screen video together with the intelligence and flexibility of digital planning. Advertisers now find new ways to be creative, measure success, and build campaigns that combine brand storytelling with tangible, data-driven outcomes.
 
The format also enables sophisticated cross-channel strategies, with CTV serving as a powerful awareness driver that enhances the performance of social media, display, and search campaigns. When audiences first encounter a brand on the big screen, they become more likely to recognise and engage with it later across other digital touchpoints. Furthermore, as CTV continues to mature, interaction is becoming a more natural part of the viewing experience. Simple features like on-screen QR codes and clickable links make it easy for viewers to respond in the moment, turning what was once a passive branding channel into one that can spark real, measurable action.
 
Navigating the challenges
 
However, despite the rapid growth of CTV, fragmentation remains one of its biggest challenges. Different services, devices, and apps create a complex landscape, making it difficult for advertisers to manage campaigns across them all. This fragmentation also affects measurement, as each platform has its own standards and reporting methods, making it hard to build a unified view of performance. Frequency control can also be problematic. A viewer might see the same ad several times through different services if those platforms are not linked or coordinated. Addressing another key concern, evolving privacy regulations require advertisers to be even more thoughtful about how they collect and use data across devices. Unlike traditional digital advertising that relies heavily on third-party cookies, CTV uses household-level targeting based on IP addresses and device identifiers. This approach naturally aligns with emerging privacy standards and regulations, offering a more sustainable path forward as the industry moves into a cookie-less era. The focus on household rather than individual targeting provides advertisers with meaningful audience insights while maintaining compliance with data protection requirements.
 
A view to the future
 
Looking ahead, interactive formats are set to evolve further, making CTV even more dynamic. Viewers will have experiences that allow them to engage with products directly from their TV screens, and shoppable ads will begin to transform television into a true commerce gateway. AI will play an increasingly important role in predicting audience behaviour and optimising creative variations for different households. At the same time, broadcasters and streaming services are exploring ways to unify measurement across linear and digital platforms, creating a more cohesive approach to television planning. With major players expanding their ad-supported tiers and more tools becoming available to smaller brands, CTV is on track to become one of the most significant advertising channels of the next decade. The appetite for ad-supported content remains strong among consumers, with many willing to watch ads in exchange for free, high-quality programming. This acceptance lays the foundation for continued growth and innovation in the space. As streaming adoption accelerates and viewing habits continue to shift away from scheduled programming, the importance of CTV as a marketing channel will only intensify.
 
In conclusion, CTV has reshaped how audiences consume video and how advertisers connect with them. By blending television's emotional storytelling with digital media’s precision and insight, CTV creates a new model for modern advertising – one that remains flexible, data-driven, and capable of delivering meaningful results. As streaming grows and viewing habits evolve, brands that invest in CTV now will better prepare themselves for the future of televised content and the next generation of advertising effectiveness. The convergence of premium storytelling, advanced targeting, and measurable outcomes positions CTV as a replacement for existing channels as well as an essential complement that elevates overall marketing performance.
