CSI: Facts and Figures

[Fool4love]

I'm writing an article for a newsletter at my school about the popularity of forensic science TV shows, and CSI is going to be my main example (obviously). So i was wondering if anyone could help me with a few specifics such as:
How many viewers does each show get per episode? (on average over a whole season)
How much is the whole CSI franchise worth?
How many countries does the show air in?
Any other CSI facts would be appreciated.

Thanks

Average viewers - for CSI: LV is 30 million viewers. "as of February 2006, CBS reported that over 90 million viewers have tuned into the series this past year alone." - Wikipedia.

Go to: http://en.wikipedia.org/wiki/CSI_Crime_Scene_Investigation for the list of countries that it's broadcasted in.

The whole franchaise is worth $700,000,000 USD, I just watched it on ET a while ago.
