Spend enough time in CTV and you start to hear the same shorthand repeated: direct is good, reselling is bad, with the goal to simplify the supply chain. That framing is easy to understand, but it breaks down when you look at the reality of how CTV actually operates.
Most publishers are not just selling the inventory that sits neatly inside their own channel. Outside of the largest players, there is rarely enough scale in owned-and-operated inventory alone to consistently attract demand. Streaming platforms have their own requirements for distribution, and buyers have their own requirements for scale, efficiency, and reach. For publishers, that means that revenue optimization requires a nuanced mix of relationships, partnerships, and deal structures that make the supply chain endemically complex. That complexity is a feature, not a bug, but it isnât beyond comprehension.
Letâs take a look at how it really works.
The Five Ways
There are a handful of common ways publishers can package their inventory–five, to be exact. These are the standard patterns behind how CTV supply actually gets to market, and for most publishers it is normal to be doing several of them at once.
- Inventory Share: The publisher and the platform split the inventory within the publisherâs channel. Each side controls and monetizes its portion independently. This is the foundational agreement that allows a channel to exist on a platform while still giving the publisher a direct stake in how its own inventory is sold. This is extremely common because most independent publishers share inventory as part of the price of distribution.
- Backfill: The publisher and platform fill each otherâs unsold inventory. If the platform cannot monetize an impression, the publisher can run demand against it. If the publisher cannot fill it, the platform steps in. This increases overall yield without…
