On-Line Advertising |
|
Just a few short years ago, before the dot-com crash, any Web site with lots of visitors was thought to be a money machine for advertisers. BlueMountain.com, a greeting card company with 11 million visitors a month, sold for $780 million, even though it had no revenues. But, shortly after the crash, you couldn¡¯t give those eyeballs away, and until recently the industry consensus was that there was little if any value in advertising on the Internet. |

To Tell the Truth |
|
The device that is widely used to detect lies today, the polygraph, is simply too unreliable. It is too inaccurate for the results to be admissible in court cases. A 2002 report by the National Research Council concluded that the polygraph can¡¯t distinguish innocent people from guilty ones. In response, the U.S. Department of Energy began relying less on the use of the polygraph to conduct security checks on its employees. |
