Here are the ratings for Episode 321 Desire from TVGuide.com
The fast overnights have CSI eking past Grey’s, 19.99 to 19.75 million viewers (though ABC, of course, rules the key demos).
However, we think TV Guide got it wrong. Many, many other sites (including ABCMediaNet) are reporting that Grey’s beat CSI for the 16th time in a row. We’d like to believe ABC.
