Non-Preemptible (NPE) TV Buys, Explained: Why More Brands Are Paying for Guaranteed Airtime

A non-preemptible (NPE) buy is a TV ad placement that is guaranteed to air, unlike preemptible or “remnant” buys, which are purchased through a bidding system and can be bumped from the schedule at the last minute. On CTV, the same structure is usually called a guaranteed buy, and the commitment is to deliver a set number of impressions rather than a set number of spots.

Preemptible or remnant inventory works the opposite way. You’re bidding for units the network can resell or reschedule if a higher rate comes in, or if the schedule changes. Most performance-driven brands start here, and for good reason: it’s an efficient way to find out what actually works for your brand on TV. But for brands looking to increase certainty around where and when their TV ads run, NPE buys can offer several important advantages.

The Differences Between NPE and Remnant TV Inventory

When is NPE the Right Choice?

Here’s the scenario that usually brings a brand to this conversation. A client starts testing in the remnant marketplace, and something works, either a specific network, a specific program, or a specific daypart. The CPA and response rate holds. So they ask the obvious question: how do we get more of that, consistently? The answer comes down to deciding if it’s worth the cost. 

At Tatari, we closely track pricing and clearance throughout the year and use analytics to help clients hit their desired budgets and performance goals. Based on that data, clearance in the remnant space can vary by approximately 25–40% from week to week. 

Some of that is manageable. Our rate bidding is aggressive and efficient, which mitigates part of the variance. But outside of bidding, a variety of factors can still cause advertisers to be bumped from spots at the last minute, which makes it harder to predict exactly how much inventory will clear.

News is a common example. Breaking news can significantly change a network’s schedule, even removing ad breaks altogether, and remnant units may be bumped on the day they were scheduled to air. Instead, an NPE buy is guaranteed to run and can provide greater certainty that an advertiser will hit its target investment.

NPE Helps Brands Hit Budgets More Accurately

For brands with less flexibility in their budgets, NPE can be an effective way to balance out the variability of remnant clearance. If a client has to spend a specific number against a specific quarter, guaranteed inventory reduces the risk that a light clearance week leaves money on the table.

NPE buys give advertisers more control over the shape of the campaign:

• When ads air: specific weeks and dayparts/programs, rather than wherever clearance lands.

• Frequency caps: defined limits, negotiated up front.

• Lead time: this control assumes inventory is available at the time of negotiation, typically a month or two in advance.
  
  

How do NPE and Guaranteed Buys Work on CTV and Streaming?

CTV and streaming work on the same logic with different units. When an advertiser pays an NPE or guaranteed rate, the publisher commits to delivering a specified number of impressions rather than airing a specified number of spots. Programmatic guaranteed deals on CTV are the same idea expressed through a programmatic pipe: fixed CPM, reserved volume, committed delivery.

Clearance on streaming is generally less volatile than on linear TV. But if a campaign requires 100% delivery, i.e., a hard impression target over a defined flight, a guaranteed buy may still be worth considering. We typically look at guaranteed inventory for clients who need to deliver a specific number of impressions over the course of a campaign.

Guaranteed inventory on streaming commands a higher CPM for the same reason NPE commands a premium on linear: the publisher is committing to deliver the agreed-upon impressions in full, and that commitment has a price. Increasingly, linear and streaming are planned together rather than as separate budgets (what we call convergent TV), so this decision gets made once, across both. If you’re weighing whether a higher CPM is justified, our piece on why all impressions are equal, but some are more equal than others covers how we think about paying up for quality.

When Should a Brand Choose NPE?

Two situations come up most often.

The inventory you want is selling out

Networks and programs do sell out, and for some brands, maintaining a consistent presence in a particular environment is critical. A mattress brand may want to ensure consistent clearance on HGTV, for example, rather than hope for it.

Credibility and scale matter as much as CPA

Tatari often works with startups and brands on the rise, where establishing credibility and creating an association with quality and scale can be especially important. A brand focused on awareness and reach may prioritize appearing alongside established advertisers or within high-profile programming — a client may look to high-profile sporting events alongside established brands like Geico and T-Mobile and use a guaranteed NPE placement to secure that environment.

Sports is worth calling out specifically, because the ground has moved. Marquee games now sit across streaming as well as broadcast. Amazon’s Thursday Night Football, Netflix’s Christmas Day games, Peacock’s Sunday Night Football as an example, means the guaranteed-placement conversation for premium sports now happens on both sides of the linear/CTV line, often within the same negotiation.

As advertisers expand beyond direct response and put more emphasis on brand-building campaigns, NPE buys can also help ensure they achieve their intended reach within specific networks, programs, or audiences.

3 Considerations Before Making an NPE Buy

Prove the Performance

Because decision-making at Tatari is data-driven, we don’t recommend an NPE buy simply because a network or program is popular. Before considering one, we take a deep dive into historical performance to confirm a publisher, network, or program has consistently delivered strong results.

What we look at:

• CPA: has cost per acquisition held steady across the period?

• Response rate: is response consistent across airings, or concentrated in a few?

• Incremental lift: is the placement driving results, or capturing demand that would have converted anyway?

• Historical data: Data-driven insights to understand whether performance has been durable enough to justify paying a premium for guaranteed inventory.
  
  

Size the Commitment

We wouldn’t typically recommend a client book 100% of a network’s media spend in NPE. A layered approach works better.

Example: $500K on HGTV for the quarter:

• 50% in NPE guarantees the presence and the budget delivery.

• 50% in weekly remnant, layered on top maintains consistent, efficient performance and preserves some ability to lean in or pull back as results move.

That structure gets you the certainty you’re paying for without paying the premium on every impression.

Time it to the Market

Marketplace conditions are a key factor when planning an NPE investment, and they can invert the usual math. Holidays, major sporting events, etc. all may spike demands and alter programming plans. Early planning can produce an actual cost benefit.

In each case, lower-cost remnant inventory becomes harder and harder to clear as more advertisers enter the market. For example, we have seen instances where a client who committed to NPE before the start of the quarter and locked in rates on the network ended up paying lower rates than advertisers who kept bidding in the remnant market and had to keep raising their rates to maintain clearance in a very competitive environment.

Assessing the Benefit of NPE

Ultimately, the question is whether the increased cost and reduced flexibility of an NPE buy are justified by the value of greater certainty, stronger placement, and/or better alignment with the advertiser’s objectives.

When the data shows that efficient performance can be maintained at the higher rate, NPE can give brands a clear and confident path to securing the inventory that matters most.

Frequently Asked Questions (FAQs)

Can NPE buys be cancelled?

Generally, no. NPE inventory is taken out of the market and held for the advertiser, so networks typically don’t allow cancellation. Terms vary by network and by the size and length of the commitment, but advertisers should plan on an NPE buy being a firm commitment for the flight they’ve booked.

How far in advance do you need to book an NPE buy?

Typically one to two months in advance. The specific weeks, dayparts, and frequency caps you can secure depend on what inventory is still available at the time of negotiation, so earlier is better — particularly heading into a tight marketplace.

How much more do NPE buys cost than remnant?

On linear TV, NPE rates have historically run 20–50% higher than remnant rates, based on Tatari’s media buying data. On CTV and streaming, guaranteed inventory commands a higher CPM than non-guaranteed. The premium is negotiated against dollar commitment, campaign timing, length of commitment, and available inventory.

What’s the difference between NPE on linear and guaranteed on CTV or streaming?

The commitment is measured differently. On linear, NPE guarantees that your spots air. On CTV and streaming, a guaranteed (or programmatic guaranteed) deal commits the publisher to delivering a set number of impressions at a fixed CPM. Streaming clearance is generally less volatile than linear to begin with, so the case for guaranteed on CTV usually rests on hitting a hard impression target rather than on protecting against preemption.

Is an NPE buy the same as an upfront buy?

No, though they overlap. Upfront refers to when inventory is bought — committed ahead of the season, usually at volume. Non-preemptible refers to what protection that inventory carries. Upfront commitments frequently include non-preemptible units, but NPE can also be negotiated outside of an upfront, in scatter or quarter by quarter.

Does NPE guarantee performance?

No. It guarantees clearance, not results. An NPE buy ensures your ad airs where and when you bought it — it does not make that placement work harder than it did in testing. This is exactly why we look for consistent historical performance over a full quarter before recommending one.

What added value comes with an NPE buy?

Networks often include extras such as on-screen banners, billboards, bonus impressions, and integrations. These can contribute to campaign performance, but they should be measured rather than taken at face value when you’re evaluating the true cost of the buy.

Should a brand put its entire network budget into NPE?

We wouldn’t typically recommend it. A layered approach — a guaranteed NPE base with weekly remnant layered on top — protects presence and budget delivery while keeping blended efficiency down. On a $500K quarterly investment in a single network, roughly half in NPE is a reasonable starting point.
