Finally know which households heard the ad — not just which ones it was sent to.
Phantone closes the attribution gap that every broadcast advertiser has lived with for decades. Not an estimate. Not a panel. A verified impression, per household, per second.
Here's what a broadcast campaign looks like with Phantone.
- 01
The advertiser or network watermarks the TV spot or ad break before it goes to air. The audio is unchanged. The signal is in.
- 02
The spot airs nationally — on cable, satellite, OTA, CTV, or streaming. Every device with the Phantone SDK in the room hears it.
- 03
The SDK decodes the signal in real time. The impression is logged — campaign ID, creative ID, timestamp, household hash — and delivered to the advertiser's endpoint within 500ms.
- 04
The advertiser sees verified impressions in real time. Not estimated reach. Not GRP projections. Verified, timestamped, cryptographically signed events — per household, per second.
- 05
Second-screen experience fires for viewers: a product offer, a 'learn more' unlock, or loyalty credit — timed to the moment the spot ends.
What the viewer experiences.
Appears 30 seconds after the spot. No app required beyond the brand or partner app.
What you see.
Phantone gave us attribution data we've never had access to before. The experience moments are what make it different.
