Derby ratings up 7 percent from '08

NEW YORK -- The Kentucky Derby's television ratings are the highest in 17 years.

NBC says Saturday's coverage of 50-1 long shot Mine That Bird's win drew a 10.2 overnight rating and 22 share. That's up 7 percent from last year's 9.5/21.

It's the highest overnight rating since Lil E Tee won in 1992.

The rating is the percentage of all homes with televisions tuned into a program, while the share is the percentage of all TVs in use at the time. Overnight ratings measure the nation's largest markets.
