Yahoo Inc. announced that its revenues for the third-quarter grew by a whopping 50%. This increase is unusual, in that Yahoo's main revenue source is online advertising, which is widely reported to be in a steep decline by analysts. In an example where less seems to equal more, Yahoo's main increase appears to be due to its entry into the paid search business, where it partnered with Overture to run advertising at the top of Yahoo's search results. Yahoo said that the paid listings helped attract advertising from businesses with small budgets. And, since the ads are topic specific to the Web page, it's likely that those seeing the ads have an interest in the product being pitched. Paid Internet listings are not flashy or interactive, but are there for information, and function much like the yellow pages.
