For years, sponsorship and media rights have been priced on impressions — a model that overlooks how long a brand is visible, where it appears on screen, and whether audiences even notice it. As budgets tighten and scrutiny intensifies, this approach no longer satisfies boards, investors, or sponsors. Enter Cost per Exposure Second (CPeS): a next-generation metric that transforms every visible second of brand presence into a verifiable asset. Powered by AI-driven exposure scoring, CPeS enables executives to negotiate with precision, justify premium rates with evidence, and align sponsorship spend with measurable outcomes. The shift marks a turning point where transparency and accountability become the foundation of sponsorship value.
