SXM Media Offers Cookieless Listener IDs

Trackers gonna track: SXM Media, the ad sales arm of SiriusXM, Pandora, and Stitcher, has launched a cooklieless personal identifier to track its listeners.  The system collects “a variety of consented listener signals and inputs” to determine which devices belong to the same individual, and uses the resulting “AudioID” for ad targeting and measurement.  Initial deployments will be limited to SXM Media’s own properties but the company plans to add audiences on other platforms later this year.
