Broadcast Platform

A Broadcast Platform is a traditional one-to-many media outlet that transmits scheduled audio or video programming over licensed television or radio spectrum to mass audiences. It monetizes primarily by selling advertising spots against its linear schedule.

Broadcast platforms supply linear inventory measured by reach/GRPs and integrated into campaign planning via audience measurement systems and daypart-based pricing. Inventory is historically sold by direct deals and upfronts, while modern broadcasters add OTT/streaming endpoints to enable addressable ad insertion, programmatic access and cross-platform campaign coordination. Because targeting is more contextual and reach-focused than granular digital targeting, buy-side planning emphasizes reach, frequency and brand-safe environments.

The market comprises public and commercial broadcasters, national networks, regional stations and their ad-sales organizations operating under regulated spectrum regimes. Sellers are broadcasters and network sales houses; buyers are advertisers, brands and media agencies purchasing spot buys, upfront commitments or programmatic/SSP-enabled inventory. Hybrid linear+streaming models create mixed revenue streams (linear spot sales, OTT subscriptions and addressable ads), driving convergence of TV and digital ad pricing and measurement standards.
