An out of date page?? That's all?
Run a google search on the US government reports on nanotech, the National Science Foundation, etc and you'll see where that page is wrong...one serious indicator of development is the funding for R&D, that number is well above the revenue figure and was growing at 25% till 2008 before the WW recession. It is still over 18%. Total research dollars since 2000" $65 billion. Over $15 billion a year.

The total VALUE of products incorporating nanotech is actually much higher than the revenue total. Here are some snippets:
