How much of this is toolbar spam?
The graph shows the relative amounts of people who use Google to search for (i.e. navigate to) Ask, NYT, and CNN.
So, if toolbar spam is involved, it's Google's toolbar.
Hmm. I just checked with quantcast, and the graphs are similar: http://www.quantcast.com/ask.com http://www.quantcast.com/nytimes.com http://www.quantcast.com/cnn.com
also it gives an estimate of 110M visitors per month. Not too shabby.
