The Dennis & Callahan Show, featuring John Dennis & Gerry Callahan, went on-air starting on October 6, 1997 from 10am to noon.  The talented duo took the day part, which was ranked eleventh at the time with men ages 25-54, to second in their first ratings book. The Show moved to morning drive (6AM-10AM) on September 7th, 1999. They quickly improved from a rank of eighth to third in the first book, and they hit #1 for the first time in the fall of 2003. D&C hit #1 again in the fall of 2004, and then again from the winter of 2006 through today with men ages 25-54.
