DeMarco anchored the 5/6 broadcast with the KCBS music, and Lower 3rds. (KCBS uses the lower 3rds differently than WCBS - they tend to use capital letters a lot on the 2nd line.)
You guys are mentioning ratings from 10/15+ years ago. It's a different time now. Numbers are going to keep going down in this day and age. People don't watch Evening News broadcasts. Period.
