nearly 20% of all TVs turned on were tuned to CBS to investigate Grissoms fate on Thursdays return of CSI. The ads teased Grissom may leave the series for good, however TVgasm can now report that he is only leaving while he is in his third trimester and it was getting difficult on production to hide his bump. Despite a strong peacock showing with EARL, OFFICE & ER, the night belonged to CBS. UGLY BETTY is still looking hot for ABC saving the day while nearly 20% of all TVs turned on GREY'S is still in rerun.
For the complete line up of Thursdays ratings 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.
