The International Herald Tribune reports that companies like Google, Yahoo, Microsoft and AOL are buying once-obscure online advertising firms for eye-popping prices. The issue reached new heights May 18 when Microsoft agreed to pay $US 6 billion for the online advertising company aQuantive. It was Microsoft’s largest acquisition, and a sign of its desire to build an Internet advertising business.
Earlier, Google agreed to buy DoubleClick, a competitor of aQuantive, for $US 3.1 billion, outbidding Microsoft. Since then, all of Google’s main competitors have bought online advertising specialists. Source: http://www.iht.com:80/articles/2007/05/20/news/msft.php
