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��셳 give those eyeballs away, and until recently the industry consensus was that there was little if any value in advertising on the Internet. |
