Catherine Herkovic and yours truly share something in common: We're in our fourth decade of exploring, then explaining, what makes the television universe tick. In Herkovic's case, Nielsen has been the home base for her exploration, with management roles there involving both national and local television research. She started this year in a new capacity -- Senior Vice President and leader of the company's Local TV transformation program, helping transform two key elements of TV audience measurement. First, there are the products designed to collect and crunch viewership information, and second, there's the data-gathering and crunching technology inside those products. Priority one for Herkovic is to expand the capabilities of both.
