Since 2000 Cornerstone Research has been dedicated to providing quality software for radio.  With over fifty years’ experience in radio programming, research, software sales and development, we understand your business.  And we love radio!

If you’ve been in radio for even a short while, odds are you’ve used one of our programs.  Cornerstone Research is the team behind three of radio’s most-used software tools: , XTrends, Analyst, and Hook Exchange!

XTrends is radio’s favorite ratings analysis software.  For diary markets, XTrends is radio’s ONLY extrapolation tool, and for PPM markets, our clients prefer XTrends’ simple interface and personal data delivery.  Every major group uses XTrends, most of them group-wide, including Clear Channel, CBS, Cumulus, Emmis, Cox, Hubbard, Entercom, Radio One, Greater Media, Lincoln Financial and Bonneville.


Analyst is radio’s premier delivery vehicle for music research data.  Many of radio’s top researchers provide their callout and music test data in Analyst.


Hook Exchange is a service that offers high quality song hooks and one-of-a-kind sophisticated software to aid in the creation, management and distribution of hook lists.

"XTrends is a fantastic service. The program is easy to use and understand and has made my ability to analyze the PPM numbers on a weekly basis a very simple process."
