OPRAH Winfrey’s visit to “30 Rock” generated a collective yawn from viewers.

Winfrey’s cameo on Thursday night’s episode didn’t move the ratings meter, with “30 Rock” averaging only 8 million viewers – down 500,000 viewers from last week’s record-setting episode.

The episode also finished third (9:30-10 p.m.) in both viewers and adults 18-49 (behind “CSI” and “Grey’s Anatomy“) and shed 300,000 viewers from its lead-in, “The Office.”
