CTV in LATAM: From Branding Accessory to Performance Powerhouse

The historical categorization of Connected TV (CTV) as a 'brand awareness' line item is dead. In the current LATAM media ecosystem, we are seeing a violent pivot toward performance-driven allocation. The data coming out of regional giants and tech platforms is no longer anecdotal; it is structural. If you are still treating CTV as a secondary reach extension, you are misreading the P&L of your media mix.

The ROAS Halo Effect Recent insights from Roku and Amazon Ads have shattered the siloed view of CTV performance. The data indicates that CTV drives an 87% higher ROAS across the broader media mix. This isn't just about viewability on the big screen; it is about the halo effect. In markets like Brazil and Mexico, where the multi-device journey is fragmented, CTV acts as the high-intent anchor that validates search and social conversions. When a user sees a high-impact creative on the living room screen, the subsequent lower-funnel click on a mobile device isn't just organic—it’s an assisted conversion that the industry is finally beginning to attribute correctly.

The Professionalization of Streaming Analytics The shift from 'guessing' to 'measuring' is fueling a new demand for specialized talent. The launch of the first 'Diplomatura en Analytics para Streaming' by UTN Buenos Aires is a clear signal of the market's maturity. We are moving past basic metrics like Video Completion Rate (VCR) into a granular understanding of how interactions and community engagement translate into lifetime value. The industry is no longer satisfied with knowing a stream happened; we need to know who stayed, who churned, and how that specific interaction influenced the next purchase cycle. This academic shift validates that the 'Gut Feeling' era of LATAM media buying is officially over.

Data and Retail Media Convergence The recent IAB Now 2026 summit in Buenos Aires, which gathered over 1,700 professionals, placed Retail Media and AI at the center of the agenda. In Latin America, the fusion of CTV with retail data is the next frontier. We are seeing the rise of 'Where Marketing is Born' as a concept that blends technology with transactional reality. By integrating first-party retail data into CTV buying strategies, advertisers are bypassing traditional intermediaries to achieve a level of precision that was previously reserved for search engines.

The Strategic Mandate For directors and CMOs, the directive is clear: move beyond the vanity metrics of linear TV. The transition to an analytics-heavy media buying strategy is no longer a luxury for early adopters; it is the baseline for survival. Those who fail to integrate cross-platform ROAS data and invest in streaming analytics will find themselves overpaying for reach while their competitors are buying outcomes. CTV is now the primary engine of the LATAM media stack. Treat it accordingly.
