Glee drew 13.6 million viewers, retaining 78 percent of American Idol's audience (20.2 million viewers), according to Nielsen overnight estimates. The show also claimed its highest-ever rating among 18-to-49-year-olds and the highest Nielsen rating of any scripted freshman show this season, according to Fox. Additionally, the episode improved 44 percent over the post-Idol-finale preview last May.
NBC placed a distant second in the demo behind Fox for the night, as The Biggest Loser (8.3 million viewers) improved 10 percent over last week in the demo. Parenthood (6.4 million viewers) remained strong against the encroaching Glee, dipping only slightly in the demo from the previous week.
