According to TVByTheNumbers.com, the Sept. 23 episode of the music-filled TV program garnered an audience of 6.6 million viewers as had the Sept. 16 broadcast.  New TV shows typically go through weeks of declining viewership as audiences drift off after initial sampling.  In the important 18-49 demographic, the show dipped a minor 3% from last week's figure.

With the official start of the fall TV season, this airing of "Glee" was the first opposite what for now is the show's regularly-scheduled competition, including the series premiere of the highly promoted ABC comedies "Modern Family" and "Cougar Town" and the season premiere of NBC's "Law & Order: SVU."

This week's episode — titled "Preggers" — included performances of the songs "Tonight" from West Side Story and "Taking Chances." 

The Sept. 30 episode will feature newly minted Emmy Award winner Kristin Chenoweth as a former classmate of Will Schuester, the Glee club director played by Matthew Morrison.
