Nielsen's Cross-Screen Measurement Platform

I've had to deal with a whole lot of acquisitions and the integration of those acquisitions have never been fantastic except for this one. And people talk about how it's challenging to integrate technology, but this is a, this is a whole other level. This is the human element before even getting into the technology part. I believe that it's the same sort of principle behind Nielsen one that we developed in 2015 to do that job. But I don't know the pieces that they've used to create the enumeration to create the cross-screen measurement platform. Got up and gone for so long.
