An ad pod is a sequence of ads delivered together in one break, mirroring the commercial pod of broadcast television. Rather than a single ad, a 90-second mid-roll might hold a pod of three 30-second spots, filled by the ad decisioning system according to rules about duration, separation, and competitive exclusion.
Pod construction is where a lot of monetization logic lives: how long the pod is, how it is filled, how to avoid showing competing brands or the same ad twice (frequency capping), and what to do if demand does not fill the whole pod. Good pod management directly affects both revenue (fill) and viewer experience (not too many, too repetitive ads).
