In an in-depth conversation with Colin and Samir, Instagram head Adam Mosseri discusses the platform's strategic evolution toward horizontal and long-form video. The shift marks one of Instagram’s biggest product changes since its launch, driven directly by changing viewer behaviors on televisions. Mosseri explains that supporting horizontal and long-form video1:35 addresses YouTube's rapid expansion onto connected television screens, where mobile time has flattened while TV viewing continues to grow. Mosseri displays mockups of long-form uploads2:38, showing horizontal landscape formats and dedicated 2x1 grid placements in the Explore tab designed to bridge short-form clips directly into full-length features.
A central focus of the interview is creator compensation and the economic sustainability of platform payouts. Mosseri details why platform bonuses remain ROI negative10:15 for short-form video: paying creators does not reliably stimulate enough high-quality, incremental viewing hours to recoup cash outlay. Because audiences often substitute other videos rather than churn entirely if a specific creator leaves, Mosseri emphasizes that Instagram must prioritize scalable, self-sufficient revenue models such as brand partnerships and subscriptions13:25 rather than indefinite capital subsidies, while keeping direct performance payouts break-even.
Mosseri also provides tactical insight into the mechanics governing Instagram's recommendation engine today. When evaluating content performance, he highlights the power of sends per reach45:55 as the single most critical signal for unconnected distribution to non-followers. While traditional video platforms optimize heavily for gross watch time, Instagram measures social utility—specifically whether viewing inspires direct messages, shares to friends, or comments. This philosophy also explains why carousels are surging23:25, as multi-slide formats allow user pacing, get second-chance feed exposures, and drive deeper intentional engagement.
Finally, the conversation pivots to generative AI and its impact on culture and creators. Addressing synthetic personalities like the viral account Jean Philanthrope52:15, Mosseri explains the platform's push to require transparency labels while guarding against false positives. He acknowledges that comedians frequently face stolen jokes retold by AI avatars54:08, forcing Instagram to refine algorithmic definitions of originality. Acknowledging growing public anxiety and hostility toward AI1:05:35, Mosseri argues that tech companies must design AI tools that empower human artists rather than displacing them.
