“Smallville” earned a 2.7 rating/5 share, according to Fast National ratings from Nielsen Media Research, slightly about its average from last season, but still nearly 13 percent off its highest rating last year. “Supernatural” also did well clocking in with a 2.3/4, its highest rating in the past two years.

The second episode of the J.J. Abrams series picked up an 8.2 rating/13 share. It lost nearly 7 percent of the audience brought in by the season premiere of “House” on Fox, but it didn’t matter. The 8.2 was a 39 percent increase over the series premiere, and helped lead Fox to a Tuesday night win.

The Fox series earned a 3.5 rating/6 share according to Fast National ratings from Nielsen Media Research, off 12 percent from its previous series low in its second premiere last week. It even finished lower than its lead-out show “Prison Break,” which ticked a bit higher with a 3.6/5.

The series premiere of the Fox series struggled to get past NBC’s “America’s Got Talent,” earning just a 5.9 rating/9 share according to Fast National Ratings from Nielsen Media Research. However, Fox once again dominated the key advertising demographic of adults 18 to 49 pulling in a 2.9 rating, followed closely by ABC with a 2.7, meaning that while total viewers may not have been out there for “Fringe,” the ones that matter to advertisers were.
