Nielsen Catalina Solutions (NCS) signed an agreement with FourthWall Media to use FourthWall’s anonymous TV viewing data to link advertising with retail sales. NCS plans to use FourthWall’s data to expand its TV panel, it said Monday in a news release (http://bit.ly/1oUU1oP). The larger footprint will deliver greater precision across NCS metrics “and enable measurement of smaller TV networks and programming as well as more niche brands,” it said.
