Z Marketing Partners (fomerly known as MZD) has been doing great advertising for over 50 years all from our home base of Indianapolis, IN. In fact we believe we’ve been the longest active agency in the State of Indiana. To add some perspective, the USA has sworn in 11 presidents in that time. ZMP? 4. We’ve changed names 4 times: Starting with Rueben, then Rueben Montgomery, followed by Montgomery Zukerman and Davis, MZD, and now Z Marketing Partners (or ZMP).
