Nielsen has launched its 2025 Upfront/NewFront Guide, a key resource for media buyers and sellers preparing for the 2025-2026 Upfronts/NewFronts planning season. The guide provides essential cross-media data and insights to navigate the evolving advertising landscape. It highlights trends such as the convergence of linear TV and streaming, with 41% of TV time now spent on streaming, and the importance of advanced audience profiles for better targeting. With Americans spending 70 hours a week on media, understanding these trends is crucial for optimizing advertising budgets. The guide aims to help buyers and sellers make informed, data-driven decisions in a complex, fragmented media environment.
