The School-Bell Flywheel: peer reconvening and the delayed youth breakout of “Golden”

Purpose Diffusion models used in strategic marketing planning do not specify how calendar-driven transitions in peer-network density govern adoption timing among youth demographics, which may lead managers to withdraw support before conversion windows open. This study aims to introduce the School-Bell Flywheel, referred to as the BELL framework, which comprises four sequential processes: Build a Reservoir, Energize Rituals, Lift into Households, and Leverage Platforms. The framework aligns marketing resource allocation with network state transitions. Design/methodology/approach The study develops theory through integration of complex contagion theory, media richness theory and consumer socialization research, using an in-depth illustrative anchor case (Netflix’s KPop Demon Hunters and the delayed breakout of its song “Golden”) with a corroborating illustration from Disney’s Encanto. Findings The study proposes that summer visibility converts to mainstream adoption when reconvening peer networks enable crossing complex contagion thresholds. Under specified conditions, institutional device restrictions are proposed to amplify adoption by channeling influence into richer face-to-face interaction. The framework is formalized in six testable propositions. Practical implications The study provides a Sleeper-Hit Risk Map assessing delayed diffusion candidacy, a phase-by-phase resource allocation playbook, and measurement guidance distinguishing delayed diffusion from underperformance. Originality/value Existing diffusion models do not link delayed adoption to a predictable, recurring institutional trigger. This study identifies school-calendar reconvening as an institutionally scheduled network-state change that creates discrete adoption windows for youth entertainment products.
