I am working on a project that deals with Statistics and gathering data.  

I am gathering data, comparing Google's stock market value compared to
the percentage they have of the digital media market.

?Google, whose shares more than doubled last year, has considerable
potential to grow. Stahlman estimates that Google's share of the $2
trillion digital services market, which he says has the potential to
expand to $10 trillion annually, is about 0.3%. He arrived at his
theoretical price -- not a price target, by any means -- by
multiplying the 6.2 multiple that Microsoft now fetches on an
enterprise-value-to-trailing-12-months-sales basis by what he sees as
Google's potential $100 billion in revenue. ??

""Mark Stahlman, the technology strategist at broker Caris & Co.,
figures Google will ultimately garner 1% of the global digital-
services economy, which will include everything from buying books to
paying a fee to store your medical and financial information. As a
result, Stahlman says, Google's revenues could grow to a cool $100
billion, which would justify a long-term target of $2,000 on the
shares. ""

I want to do an experiment to see if this is true if google has 1
percent of the global digital services economy, would it result in
$2000 per share price.


H0  :  Google?s Stock price (goog) is independent from the percentage
they have in the global digital media market.

H1 :  Google?s Stock price (goog) correlates directly with the
percentage they have in the global digital media market.

The day Google went Public on August 19, 2004 is the first day I can
track the stock price accurately.
I only want to use data that is accurate, but I will be interested in
seeing some data that forecasts or projects the percentage that they
will have with in 3 months, but no further.
Therefore, the main objective is getting accurate numbers of the total
Digital media services (global digital- services economy) from start
date of August 19, 2004 up to today.

I would then like the number, or percentage that google will has of
the digital media.
Ideally the dollar value is the best. 
Hence.  100 billion divided by 10 trillion is 1 percent!  

So the dollar values of each will be the best data.  
This data can be by weeks, days, or months or quarters.  

What makes up the the global digital- services economy? 

What is referred to as the global digital- services economy?


Please ask for any clarifications.
