Comcast Research: TV Amplifies Recall, Engagement, Conversions
Comcast Advertising published new research titled "TV Makes Memories" showing that TV (traditional and streaming) acts as a full-funnel driver that strengthens other channels. The study reports that pairing TV with search yields up to 8.7× higher ad recall, with smaller lifts when paired with social (1.8×) and podcasts (1.6×). Adding TV increased downstream actions: TV + social raised website visit likelihood by 110%, TV + search raised brand discussion by 119%, and TV + audio raised information-seeking by 207%. The research also found search recall falls 23% when AI-generated summaries are used, suggesting TV helps brands remain top-of-mind as discovery becomes more automated.
Research from a major media sales house (Comcast Advertising) quantifies TV’s multiplier effect on search, social and audio and highlights an AI-driven drop in search recall — findings relevant to media planning, measurement and cross-channel strategy but not a platform policy or industry-shifting regulatory change.

Comcast Advertising Study Shows TV and Streaming Boost Results
Comcast Advertising, the advertising division of Comcast, released findings from its new Multiscreen Performance Report, which analyzes how TV and streaming campaigns impact the buyer journey. The study combines Comcast campaign data with independent measurement partners to examine attention, reach, consideration, and website activity. Key findings include: multiscreen TV campaigns deliver 2X incremental return on ad spend and 2.4X more website visits compared to single-tactic campaigns. Sports streaming campaigns, tied to events like the Milano Cortina Winter Olympics and FIFA World Cup 2026, achieved 52% unique reach and were 10x more effective at reaching hard-to-reach households than TV alone. The report emphasizes that TV and streaming together maximize reach, with traditional TV providing 71% of unique reach and streaming 21%, with only 8% overlap. Addressable advertising also delivered a 38% incremental sales lift. The report aims to help advertisers make more informed media investment decisions.
Unlock TV's Halo Effect to Boost Your Marketing Impact
TV advertising can have a halo effect, meaning it boosts performance on other marketing channels. The article explains that many marketers underestimate TV’s influence because attribution often emphasizes last-click results. Tatari researchers measure this effect by dividing website traffic into two groups: visitors who viewed a TV ad within the previous seven days and those who did not, then comparing conversion rates. Across 100 brands with social marketing-driven traffic, Group A’s CVR tended to be higher than Group B’s. Nine out of ten brands saw higher CVRs when exposed to TV ads; 60% of companies saw a CVR lift greater than 50%; and 33% saw a lift above 100%. The piece argues that campaigns should balance performance with reach, since broader TV exposure can amplify digital channels and raise overall brand impact. The data suggest TV can double or even triple conversion rates when aligned with digital efforts.
CMO-CFO Relations: A Two-Way Street
Funnel's Carl Ronander argues that CMO-CFO relationships are often one-sided, with marketers expected to adopt finance's language while finance fails to understand modern marketing's long-term value. He emphasizes the need for marketers to speak in credible data, while CFOs must recognize that digital's deterministic click-based era has ended due to privacy regulations and AI-driven zero-click searches. Ronander points to Nike's CFO David Denton and CMO Nicole Graham as a live test case. He references Funnel research showing only 13% of marketers communicate very well with finance, and LinkedIn B2B Institute data indicating 96% of B2B marketers expect campaign effects within two weeks—which he calls unrealistic. The article advocates for aligning on long-term investment frameworks, noting that CMO tenures are shrinking to 4.1 years, underscoring the need for mutual understanding and better reporting.
