This marks the first time Nielsen will offer ongoing audience estimates of television viewing in out-of-home locations.
Nielsen is offering the national out-of-home measurement service as well as local out-of-home services in New York, Chicago, Los Angeles, Miami, Houston and Denver. Sample participants are asked to carry mobile phones that include metering technology developed by IMMI. The phones collect passive digital signatures from television telecasts that IMMI will match with audio signatures collected by IMMI from actual telecasts. The signatures are then transmitted to IMMI computer servers for reporting.
