Care to speculate how many AdSense accounts exist today compared to June, 2003 when I first started out with AdSense?

I think in 2003 I worked out by cheque numbers that there were about 45,000 accounts however today Google gives us an approximation on the log-in page:

Watch the video tour and learn why over 2 million publishers of all sizes worldwide are using AdSense.

Just how accurate that is I have no idea.
