Television ratings for the first and second round of the NCAA tournament are up 6 percent from last year.

Overnight ratings released Monday show CBS earned a 5.4 rating
and 12 share, up from a 5.1 rating and 12 share for the first two
rounds in 2008.

On Sunday, the overnight rating was up 10 percent from 2008. The
final group of games, including a tight contest between top-seed
Louisville and surprise Siena, earned an 8.1 overnight rating and
14 share, the highest rating for the 5-7:45 p.m. EDT slot since an
8.2 in 2006.

A rating is the percentage of all homes with televisions
watching a program. The share is the percentage of all TV sets in
use at the time. Overnight ratings measure the country's largest
markets.
