Google Now Tracking 88% of Website Domains

We all know Google is the primary market share leader in search, but I found this  recent study published by graduate students at University of California, Berkeley fascinating. The study showed that Google is now the leading analytic footprint on the top 100 sites in their study.

As you can see from the chart below, Google Analytics was found on 81% of the top 100 sites, while DoubleClick (owned by Google) was in second place, by being found on 70% of those sites. Microsoft came in third with Atlas showing up on 60% of those sites. Here is the chart:

Now, when you combine Google Analytics, DoubleClick, AdSense, Google Widgets, Google FriendConnect and others, Google has a 88% footprint on those sites:

What are your thoughts on Google’s stronghold on the web in general? Does it create privacy issues?
