Add a little fuel to the fire on whether or not Fox should pick up a second season of "Terminator: The Sarah Connor Chronicles" as the action series based on the popular movie trilogy finished its first season strong.

The first hour of the doubleheader earned a 4.7 rating/7 share according to Fast National ratings from Nielsen Media Research, finishing second in the 8 p.m. hour behind a Barbara Walters special "The Royal Family" on ABC. It finished ahead of "My Dad Is Better Than Your Dad" on NBC, and sitcoms on CBS.

The audience for "Sarah Connor" actually grew in the 9 p.m. hour, finishing at 5.0/8, according to Zap2it. It finished fourth, however, behind the second half of "The Royal Family," "Deal or No Deal" on NBC and comedies on CBS.

Fox finished fourth for the night with a 4.9/7, behind ABC's 7.7/12, NBC's 5.7/9, and CBS' 5.4/9.

However, Fox did extremely well in a key demographic of adults 18 to 49, tying ABC for the night with a 3.1, followed by a 2.8 household rating from NBC and CBS at 2.6.

Fast Nationals usually provide a snapshot of what Americans are watching by pulling numbers from the top urban markets that includes both live viewing and same-day timeshifted viewing. A rating point generally represents more than 1.1 million households while the share indicates the percentage of televisions turned on that was tuned to the specific program. These numbers typically shift when final ratings are issued.
