Nielsen's newly-launched hybrid audience measurement combines both user-centric (panel) and site-centric (tag-based) measurement to generate a comprehensive view of online behavior by incorporating visitors from mobile and tablet devices, secondary PCs and access points outside of the home and work locations to provide a Total Internet Audience measure.  This new data can be accessed through Nielsen NetView by selecting the "US (Hybrid)" country from the drop-down menu in the upper right hand side of the interface.  Please contact Client Services for more information.
