Got a kick looking at the Web Analytics Solution Market Share that I saw today on WebAnalyticsbook.com; Sebastian Wenzel always comes up with valuable information that I don't see anywhere else:

What the chart doesn't reveal is the total amount of money spent on each platform in November and December (which would be hard to find out, but much more revealing).

For one thing, Google Analytics is free, that's partly why it has such a big market share.

Interstingly, Omniture/Visual Sciences/Websidestory/HBX has 10 times the Market share of Coremetrics.  

Yes, we're talking about companies and money spent.
