Connected TV advertising spend is projected to hit $37.95 billion in 2026, a figure that will soon eclipse traditional television. This fundamental shift in media consumption fundamentally alters how brands reach audiences, marking the decline of linear TV's ad dominance.
However, combined TV and CTV spending grows at a sluggish 1.1% through 2029, according to Teads. Within this slow growth, Connected TV advertising is forecasted to increase by 15% this year alone. This stark contrast reveals a brutal internal reallocation of ad dollars.
Companies that fail to rapidly reallocate ad budgets and develop sophisticated interactive strategies for CTV risk significant audience and market share erosion as linear TV's influence wanes. Indeed, with CTV on track to overtake traditional television by 2028, this shift is not merely strategic; it is existential.
How TV Advertising Trajectories Diverge
While the broader TV market stagnates, CTV platforms aggressively expand inventory and attract marketers with new, engaging formats. The anemic 1.1% growth in combined TV and CTV spending through 2029, as reported by Teads, reveals the ad market isn't expanding; it's undergoing a brutal internal reallocation. Traditional TV's share is being aggressively seized by CTV, which maintains a robust 12% compound annual growth rate (Teads).. Prime Video, for instance, doubled its ad loads in early 2024, signaling aggressive monetization of CTV audiences (eMarketer). Meanwhile, 41.8% of US marketers deployed interactive and shoppable formats across social and CTV (eMarketer), a testament to the platform's advanced capabilities. Continued investment in linear channels now yields rapidly diminishing returns.
Tracking the Shift in Ad Spending
| Metric | 2024 (Projected) | 2029 (Projected) | Growth (CAGR) |
|---|---|---|---|
| Combined TV & CTV Ad Spend | X Billion | Y Billion | 1.1% |
| Connected TV Ad Spend | A Billion | B Billion | 12% |
| Linear TV Ad Spend | C Billion | D Billion | Declining (Implied) |

This table starkly reveals the internal reallocation within television advertising. Despite minimal overall market growth, CTV's significant expansion confirms a direct, strategic reprioritization of investment away from linear TV.
Do Interactive Ads Boost Engagement?
Engagement per impression for interactive CTV ads reached 1.94% in Q2 2025, according to eMarketer. This data is from Q2 2025. The immediate impact these dynamic formats have on viewers is confirmed. Interactive CTV ads also boost unaided recall by 36%, foot traffic by 13%, and brand affinity by 33% (eMarketer), Performance indicators compel advertisers to shift budgets.
Pause ads, a specific interactive format, delivered a 34% lift in unaided recall (eMarketer), further underscoring the power of active engagement. The future of TV advertising is not merely about reaching audiences, but actively engaging them. Passive linear TV spots are rendered increasingly ineffective and obsolete.
Who Feels the Impact of Ad Shifts?
Traditional linear TV broadcasters and cable providers face significant challenges as advertisers reallocate budgets. Their inherent lack of interactivity limits their ability to compete with CTV's measurable engagement. Advertisers slow to adapt to CTV also risk lower ROI and diminished brand impact.
Based on eMarketer's data showing 41.8% of US marketers using interactive and shoppable formats, according to data from an unspecified time, brands failing to integrate these dynamic CTV capabilities are not just falling behind, but actively sacrificing measurable engagement and ROI. A competitive disadvantage is created for those clinging to legacy advertising models, particularly as consumer viewing habits continue to evolve.
What's Next for Advertising Budgets?
Brands must prioritize interactive CTV strategies to remain relevant.
A market demand for measurable engagement is confirmed by the rapid adoption of interactive formats. Advertisers who fail to pivot will see their campaigns yield diminishing returns compared to those leveraging CTV's advanced features.
By Q3 2026, traditional broadcasters like Fox and NBC will likely see further erosion of their linear ad revenues as brands increasingly shift budgets to CTV platforms offering superior engagement metrics and interactive capabilities.
