Connected TV grew up on a borrowed promise: browser-style addressability on the living-room screen. The identifiers underneath that promise — device IDs, ACR matches, stitched identity graphs — are thinning every quarter as privacy policy tightens and platforms wall their gardens. The panic response is to buy a better graph. The durable response is to notice what CTV actually is: a household medium, on a screen that geography describes natively.
The state of CTV identity in 2026
Third-party cookies never lived on television. CTV addressability was assembled from device identifiers, ACR data and probabilistic household graphs — each an approximation, each with a match step, each losing coverage as consent regimes and platform policies narrow what can be joined to what. The infrastructure still works; it just reaches less every year, at the same price.
What signal loss costs a campaign
Illustrative arithmetic — substitute your own vendor's rates, the shape is what matters: a 60% onboarding match, times 70% graph household coverage, times 50% identifier presence in the bid stream, leaves roughly 21% of the audience you paid to build actually reachable. The rates vary by vendor. The multiplication does not.
CTV was always a household medium
The television is the one screen a household shares. The buying unit was never really the individual — IDs were a workaround to make a household medium behave like a browser. Geography needs no workaround: a census block group describes households directly, and the cohort built from it maps to the screen without a match table in between.
Geographic cohorting, mechanically
Every U.S. census block group is scored on public demographic data, live search and social intent, and foot traffic; block groups sharing a data signature form a cohort; threshold methodology decides which geographies qualify; the cohort activates as a segment. Household-native from the first step — which is why AMAP measures up to +85% CTV addressability versus ID-dependent segments.
The scale is already sitting there
In the August 2026 AMAP Index pull, the Fantasy Sports and Sports Betting cohort alone showed 21,698 addressable screens and 10.8 billion monthly addressable impressions in the New York DMA — household-level scale with no match table gating any of it. The same geography carries CTV.
Activating in your seat
The cohort ships to The Trade Desk and every major DSP as geo-native targeting for CTV and display, or plans directly against DOOH inventory. One definition, every screen, nothing to decay.

Common questions
How does audience targeting work in CTV without cookies?
The audience is defined by geography — census block group cohorts scored for the target behavior — and CTV buys against geography natively. No cookie, device ID or match step is involved.
What happens to my CTV reach as device IDs disappear?
ID-dependent reach shrinks with every hop that loses coverage. Geography-defined reach does not change, because no identifier is required to qualify a household.
Do geographic cohorts replace my ID-based CTV buys or extend them?
Both patterns run today: some buyers replace decaying prospecting segments outright, others layer cohorts to recover the households their graph no longer reaches.
