IMMI, a San Mateo, CA-based mobile-based ad tracking and research firm.
The IMMI phone randomly samples 10 seconds of room audio every 30 secondsâ€¦these sample are uploaded continuously to the IMMI servers. IMMI also tracks all local TV and radio outlets, and then compares mobile-uploaded signatures with the IMMI-monitored TV and radio broadcasts. The mobile phone also receives a signal from an IMMI â€œBluetooth beaconâ€ when the panel member is at home, so the servers can interpret media exposure as â€œinâ€ or â€œout-of-homeâ€.
