Strata Marketing Inc. is a Chicago, Illinois-based software company involved in connecting media buyers and sellers.

[2] The company that became Strata was founded in 1983 by Roger Skolnik, PhD, an adjunct professor at the University of Illinois at Chicago.

These experiences led him to develop methods for analyzing radio audience information and making it available for both sales and programming.

To develop and market software tools for these methods he launched Media Service Concepts.

For agency clients, Strata provides a suite of tools for planning, buying, stewardship, optimization and billing across all forms of media, including TV, cable, radio, print, digital and outdoor.
