If you weren't already aware of just how much information offline marketers possess about you, the sheer number of catalogs you received over the holiday season should clue you in. Going forward, several of our BT experts agree that we're likely to see this offline information being merged with online data.

Datran's Knoll says such online and offline integration represents the next evolution of behavioral data, enabling marketers to gain greater insights into each individual person. However, he also notes that such integration will need to be done in an anonymous way.

Proclivity's Gilbert agrees with Knoll. He notes that additional contextual data enable marketers to better target -- and retailers to better serve -- consumers. "I think we're going to start to see a lot of convergence between the offline and online world," Gilbert says. "We're literally allowing some of our retailers to better service a customer in the store, on the website, and when they call in to a call center."
