Despite a slow decline since its season debut, Lost saw a spark of life last night. Yesterday’s episode saw the return of the Oceanic 6…and the viewers. But, as we know, there isn’t anything Jack or Ben can do to topple American Idol. FOX easily won both categories this Wednesday.

8pm

• American Idol (24.4 million, 8.9/24 in 18-49) did about the same as last week.
• The New Adventures of Old Christine (2.0/6) and Gary Unmarried (2.1/5) both pulled in 7.3 million.
• A Lost* repeat (5.6 million, 1.9/5) picked up 1.2 million.
• Knight Rider (5.5 million, 1.5/4) remained steady.
• Privileged* (860,000, 0.3/1) lost 240,000.

• Life (5.2 million, 1.5/4) improved by 500,000.
