The notion of addressable TV, a scenario in which broadcasters and marketers "narrowcast" content on a one-to-one basis to a viewer, is still very much in the early stages, but it can become a reality if marketers use consumer data to reach specific individuals.

This was one of several topics discussed wih Jen Soch, Managing Director of Global Accounts for MEC, a unit of WPP. 

Soch was a speaker as last week's BRX Video Summit in New York.
