Before ad exchanges, media inventory was exclusively purchased through direct negotiations with publishers. This worked fine in the early days. But as more publishers popped up, the process became lengthy and hands-on.
Ad exchanges helped alleviate this by streamlining ad buying with a technology-driven approach. This gave marketers the ability to purchase ad inventory on a per-viewer basis using real-time bidding (RTB), which brought us into today’s world of programmatic advertising.
But ad exchanges were only the start. More platforms designed to automate media buying came into the picture, and the online advertising ecosystem grew in complexity.
Today, the ad tech supply chain is made up of supply-side platforms (SSPs), data providers, ad networks, demand-side platforms (DSPs), and more. While each component plays a role, it can be tricky to understand how they fit together.
In this primer on ad exchanges, we spell out what ad exchanges are, how programmatic media buying works, and tips for marketers navigating the complex world of connected TV (CTV) advertising.
Ad exchanges provide a place for vendors to buy and sell TV inventory using programmatic real-time bidding. These digital marketplaces connect advertisers, supply-side platforms (SSPs), demand-side platforms (DSPs), and publishers. Popular ad exchanges in the connected TV (CTV) industry include OpenX and Magnite.
The benefits of ad exchanges are many. They enable a more data-driven approach to advertising, which means less ad waste and more relevant viewing experiences. What’s more, the efficiency of programmatic advertising can’t be beat.
One major concern with ad exchanges is ad fraud. Since ad exchanges operate in a digital space with numerous intermediaries, there's a risk of fraudulent activity such as bot traffic or ad stacking.
Another limitation is inventory quality and breadth. Because ad exchanges rely on relationships with publishers to access their inventory, advertisers may face restrictions in reaching their desired audience or accessing premium placements depending on the ad exchange they use.
Let’s back up and look at what options marketers have when buying CTV inventory to explore this further.
CTV ad inventory can be bought in two ways: programmatically using an ad exchange or via direct sales. Here’s how the two compare.

Programmatic ad buying provides more flexibility and efficiency than the direct sales approach. For this reason, almost 90% of CTV buys are transacted programmatically. But within the programmatic category, marketers
face another crossroads between open and private marketplaces.
Ad exchanges come in two different flavors: open ad exchanges and private marketplaces. The difference between the two comes down to inventory quality and access.
Because PMPs combine the premium content that media buyers demand with the efficiency of programmatic buying, they’re often the best option. But to gain access to a PMP, advertisers need to establish relationships with publishers or work with a CTV provider like Strategus with a network of inventory partners.
Machine learning, also referred to as AI, is the driving force behind ad exchanges. It’s what allows ads to be bought on a per-viewer basis without any human intervention during the bidding process.
More specifically, the programmatic ad-buying process works as follows:
What occurs behind the scenes is painstakingly complex. But for the viewer, it’s seamless. So why are there so many moving parts? Let’s take a closer look.

Serving as the central hub, ad exchanges connect SSPs and DSPs, facilitating the real-time auction of ad impressions. The instantaneous nature of these auctions allows for efficient and competitive ad buying, ensuring that the highest bidder secures the ad space.
On the flip side of SSPs, DSPs represent advertisers. They evaluate bid requests from SSPs and use algorithms to decide which ad impressions to bid on and at what price. DSPs play a crucial role in ensuring that advertisers' messages reach the right audiences.
Ad networks may also participate in the bidding process as resellers. These aggregate inventory from multiple sources and offer it to advertisers, providing additional options for reaching their target audience. Many ad networks buy inventory from ad exchanges and then mark it up — only further complicating the CTV supply chain.
Data is the backbone of programmatic advertising. Data providers supply valuable information about user behavior, demographics, and preferences. Advertisers leverage this data to make informed decisions and target specific audience segments effectively.
Given the complexity, the question arises: how can marketers simplify the process of CTV media buying while still capitalizing on its potential? This is where managed CTV services enter the picture. Rather than navigating the intricacies of ad exchanges and forging relationships with multiple vendors, many marketers opt for a managed services approach, which offers personalized guidance and hands-on execution.
The CTV ecosystem grows in complexity each day. Countless ad networks, DSPs, ad exchanges, and more vie for media buyers’ attention. Getting the full benefit of CTV requires integrations across the ecosystem, as well as expertise.
Agencies and brands looking to take advantage of this growing channel must either build out a roster or vendor partnerships and commit substantial budget to monthly minimums, or partner with a managed services CTV provider.
