Nielsen, after its rebranding efforts and under new ownership, has been on an acquisitions tear on its mainstay analytics side: it bought mobile analytics firm Telephia and blog buzz firm BuzzMetrics, last year, bought a stake in NeuroFocus earlier this year, and now has bought out Utah-based TV analysis company Audience Analytics and its Audience Watch software, reports THR. The technology acquired will become the primary delivery mechanism for Nielsen’s DigitalPlus product, which will provide metrics on interactive television data and VOD transactions, the company said. In addition, with this purchase, the company will develop a single platform to process TV, Internet, mobile and consumer data sets.
