Programmatic advertising is the automated buying and selling of ad inventory through real-time auctions rather than manual insertion orders. When an ad opportunity arises, the platform's supply-side stack offers the impression to demand sources, which bid; the highest valid bid wins and its ad is served, all in milliseconds.
For OTT it is the engine behind scalable AVOD/FAST fill: it connects a service to broad demand without negotiating every deal directly, and techniques like header bidding put multiple demand sources in competition to raise yield. The trade-offs are revenue share to intermediaries, the need for brand-safety controls, and added technical complexity in the ad path.

Fora Soft Video Engineering Handbook
Programmatic advertising fills ad breaks through real-time auctions, and slow ad responses or failed creatives show up as gaps in playback. We wrote seven volumes covering the video stack; for programmatic ads start with Volume 3 on players and the economics of streaming, then Volume 2 on manifests and ad markers, with encoding in Volume 1. Written by Nikolay Sapunov, CEO at Fora Soft.
