That
...Internet survey usage data provided by 'web measurement firm' ComScore (THE data used by so many investors to gauge + predict the earnings results of Internet Ad companies like Google, Microsoft, Baidu, Yahoo, etc.) is based on a worldwide sample size of (ONLY) 2 million users.

For some perspective, the entire U.S. population is about 305 million. The world's population? About 6.7 Billion. Both stats courtesy of Wikipedia.com.
