Nothing new about FOX on a Tuesday night taking first and second with American Idol having 10.9/28 and House having 9.2/22. ABC takes third with Primetime (special) having 4.0/10.
Coming in forth was Dancing With the Stars having 4.2/10 . And rounding out fifth, with an "I, personally, cannot keep up with how many of these shows there are," NCIS having 2.6/7. No offense, just trying to create an even spacing to fill the top area.
For the complete ratings from last night and who won the night (in key demos), stick around after the jump. . .

How do I read these ratings?
A Nielsen rating may look like this:
8pm - NBC - TVgasm The TV Show - 10.0/18
Focus on the 10.0/18. The RATING, 10.0, on the left represents the actual number of households that watched a show. One rating point equals 1,102,000 households. The SHARE, 18, on the right represents the show's proportion of the total households watching television at that time.
For example, TVgasms TV Show has a 10 rating/18 share. That means 11,020,000 households are tuned in to the show and 18% of all the households with a TV turned on are watching that show.
Ratings and Share are customarily broken down for various DEMOs -- a demographic grouping of viewers, like 18-49 adults or 2-12 children or 18-34 women, etc. Advertisers, and therefore networks, covet the 18-49 adult demo, and so tend to concentrate on that number.
