Amazon's first-party data is rightly celebrated. The ability to target audiences based on actual purchase behaviour, rather than inferred interest, is a genuine structural advantage over most other advertising platforms. But in conversation after conversation with brand and agency partners, we find that the media benefits of Amazon's ecosystem are less well understood than the data story.

In the latest edition of our monthly #AskVector series, we address that gap directly. Here is what your brand can access through Amazon's media ecosystem, and why it deserves serious attention in your 2026 planning.

Amazon at scale: the UK viewing picture

The starting point is reach. There are an estimated 53.1 million digital video viewers in the UK in 2025, and those viewers are spending an average of 3.92 hours per day watching TV and digital video. That is a significant daily media habit, and understanding where it is distributed matters for planning.

Prime Video holds a 22% share of commercial viewing in the UK, making it the largest single commercial streaming platform by audience share. Netflix follows at 18%, with Disney+ at 5% and Channel 5 at 4%.

The practical implication is significant: Vector's brand partners can now access almost half of all commercial viewing through Amazon alone, combining Prime Video's 22% share with the additional inventory now accessible through the Amazon DSP's partnership with Netflix. No other single planning relationship delivers that breadth of premium streaming reach.

The ad formats available

Understanding what Amazon's media ecosystem can deliver means understanding the range of formats available. These span several distinct environments and viewer contexts.

In-stream video ads are premium non-skippable placements delivered within streamed content. They offer the undivided attention of an engaged viewer, in a lean-back viewing environment, with the measurability of digital.

Interactive CTV ads take the lean-back format a step further. Voice or remote-click shoppable overlays allow viewers to interact directly with an ad from their sofa, moving from awareness to intent without leaving the content environment. This is a format that simply does not exist in traditional television advertising.

Pause ads appear when a viewer pauses content, delivering an interactive brand creative at a moment of natural attention. The viewer has chosen to stop; the brand fills that pause with a relevant message.

Binge ads and sponsored viewing operate on a different model. A "brought to you by" brand association offers viewers ad-free episodes in exchange for exposure at the start of a viewing session. The result is a positive brand association — the brand has given the viewer something — rather than an interruption.

Home screen and sponsored tile ads on Fire TV place static or video brand tiles on Fire TV's main menu, reaching viewers at the precise moment they are deciding what to watch. It is high-visibility placement in a low-clutter environment.

The media benefits

The formats above are only meaningful in combination with the benefits that Amazon's infrastructure provides.

Massive reach. Tens of millions of monthly Fire TV and Prime Video households globally, with the UK share accounting for a substantial proportion. This is not niche inventory.

Data-driven targeting. Amazon's commerce and viewing data enables audience segmentation that goes far beyond the demographic and interest categories available elsewhere. Brands can reach people based on what they actually buy, search for and watch, rather than what they are assumed to want.

Closed-loop measurement. This is the benefit that differentiates Amazon most clearly from traditional TV advertising. Amazon can connect ad exposure to browsing behaviour to purchase outcome, creating a measurable chain from the top of the funnel to the point of sale. That level of attribution has historically been impossible in a premium video environment.

Premium content. Ads appear in trusted, high-quality environments including Prime Video originals, Fire TV Channels and live sports content. Brand safety is a given rather than a variable.

Omnichannel synergy. Amazon's media formats do not operate in isolation. They integrate with Sponsored Ads, DSP display campaigns, and Amazon Marketing Cloud analytics, creating a unified view of how media investment is performing across every touchpoint in the customer journey.

What this means for your 2026 media plan

The case for Amazon as a media platform, rather than simply a retail or performance channel, has never been stronger. The scale is there. The formats are mature. The measurement capability is genuinely differentiated. And the data that underpins all of it continues to expand.

For brands still treating Amazon primarily as a place to run Sponsored Products, the media capabilities described above represent a significant untapped opportunity. For brands already active on Amazon DSP, the addition of Netflix inventory and the continued growth of Prime Video's audience makes the case for increasing investment clear.

2026 planning is the right moment to reconsider where Amazon sits in your overall media architecture.
