Addressable Advertising
Addressable advertising delivers different ads to different households or devices watching the same program — the targeting paradigm that underpins all of CTV and the growing addressable-linear footprint inside traditional pay-TV.
Addressable advertising is the structural answer to a problem broadcast TV could never solve: every household watching the same show wanted to be sold something different, and the medium had no way to do it. The category exists in two distinct shapes that are now converging. Addressable linear TV — the older surface, anchored in the cable industry’s set-top-box footprint — uses MVPD ad-decisioning systems to swap targeted spots into the two minutes per hour of inventory the operator controls inside live linear feeds. Comcast’s FreeWheel and the On Addressability consortium represent the consolidated sell-side here; the addressable-linear pool is small relative to total linear inventory but commands a meaningful CPM premium. Addressable CTV is the bigger story: streaming inventory is IP-delivered and therefore addressable by default, which is why eMarketer’s CTV forecast and the addressable-advertising forecast are increasingly the same conversation.
The buy-side stack is familiar — The Trade Desk and the holdco DSPs route demand; SSPs like Magnite and PubMatic intermediate; smart-TV OEMs (Samsung, Vizio, LG) increasingly behave as both inventory sellers and identity owners by virtue of their ACR data. The activation layer is where the category is most actively rewiring itself in 2026: as third-party cookies retire and CTV walled gardens harden, the holdco identity stacks (Omnicom’s pending IPG combination, Publicis’s Epsilon-CoreID assets) are repositioning as the connective tissue between first-party advertiser data and addressable inventory.
The constraint on growth is no longer supply or buyer appetite — Go Addressable’s 2025 intent survey shows 43% of large advertisers planning to increase spend in 2026, with overall satisfaction at 86%. The gating constraint is measurement currency. Until Nielsen, VideoAmp, iSpot, and Comscore reach a stable detente on cross-screen addressable measurement, the category’s premium pricing has a ceiling — and that ceiling is the next 24 months of trade-press argument.
