Programmatic Guaranteed vs. Upstream: What's the Difference?

If you buy CTV advertising, you've likely encountered two approaches to securing premium streaming inventory: Programmatic Guaranteed (PG) and direct buying. A newer option — Upstream — is changing what direct buying can do. Here's how they compare.

What is Direct IO (DIO)?

With traditional DIO, buyers negotiate directly with publishers such as NBCUniversal, Tubi, or Disney to secure inventory.  Some will refer to it as the “old school” way of buying TV (true!), but DIO still offers several advantages over programmatic:

• Zero risk for fraud. Direct publisher connections mean your ads run on verified, premium streaming apps. The bot traffic, device spoofing, and counterfeit inventory that plague programmatic CTV simply don't exist in a direct deal.

• Total brand safety. Publishers will tightly control the program and the ads that run alongside it, eliminating any risk of embarrassment.

• No intermediary DSP-SSP fees. Programmatic typically extracts 30–50% of advertiser spend through DSP, SSP, and data costs — the dreaded "ad tech tax." In a direct deal, that money stays in the media: resulting in better CPMs and better campaign performance.

• Broader access to premium inventory such as live sports, sponsorships, and custom integrations (think Super Bowl).

• Greater placement transparency.  You know exactly where your ad ran, against what content, and how the campaign performed.

This explains DIO’s resilience in the market: today, we estimate that $8B of CTV inventory (out of ~$30B) is still transacted this way by the larger brands and agencies.  And short of automation (more on that below), it is also what publishers prefer.  Rather than seeing their valuable impressions being picked off anonymously by a DSP, they get to know the brands, budget, and goals. A true partnership!

The main drawback of DIO is the lack of automation. Since it is labor intensive for publishers to process direct buys (and also prone to errors), it means that DIO is typically only available to larger brands spending significant amounts in a single campaign.

What is Programmatic Guaranteed?

Programmatic Guaranteed (PG) is a method of buying reserved CTV inventory through a demand-side platform (DSP) such as The Trade Desk, DV360, or Amazon’s DSP. The “guaranteed” element means inventory is reserved in advance — similar to a traditional DIO — but executed through programmatic infrastructure.

PG became popular not only for its programmatic automation, but also the digital-style controls it enables, in particular, the ability to buy audiences (as opposed to stand-alone programs or shows) and manage frequency across multiple publishers.

Today, an estimated $7B flows through PG pipes annually. The reason why Programmatic Guaranteed is not usurping DIO is articulated in the benefits associated with DIO (and listed in the bullet points above): fees, lack of transparency, etc. This should not be a surprise. After all, when buying PG, you’re buying guaranteed outcomes through a (programmatic) machine that, let’s face it, was built for auctions.

Introducing Upstream

Upstream brings together the best of Programmatic Guaranteed and DIO. In fact, if they had a love child, they’d name it Upstream.

Upstream, part of Infra TV, gives advertisers  direct API integration into the publisher ad server.  Since there is no DSP or SSP involved, there is no risk of fraud, no fees, and access to more brand-safe inventory, while keeping all of the benefits of programmatic. Upstream is not some SPO offering via header bidding (which in itself is programmatic) or worse, a curation effort.

Upstream is a parallel operating system alongside programmatic for publishers to sell their most priced and highest quality inventory with better automation, speed, and scale - without slapping on SSP fees.  For brands, Upstream unlocks access to the highest quality inventory, massive reach, and at a lower cost (no DSP fees!) without the need to transact large amounts.  Even smaller brands can now buy quality impressions like an NFL playoff game - inventory which is not even available in programmatic pipes!

The simplest way to put it: PG is DIO with programmatic pipes attached. Upstream is a whole new category, built from the ground up.

Is the Future Upstream or Programmatic?

The answer isn’t a matter of either/or - it’s both, depending on the need. Programmatic is not all bad, especially as it comes to precise targeting (e.g. accessing very niche audience segments or retargeting via CTV).  For certain brands or certain parts of a campaign, this granularity makes up for the issues surrounding programmatic.

Remember, however, that targeting is not an end-goal; it is a means towards performance.  Furthermore, in the world of TV advertising, reach and scale are often more important than targeting and direct-response metrics. For brands who want both scale and quality, Upstream is the way to go. While Upstream may lack certain targeting capabilities, it offers mass scale and can be measured and continuously optimized for performance. But don't just take our word for it; 400+ brands and agencies already prefer this approach working with Tatari today.
