That's bad news for Yahoo and AOL in particular, which are heavily dependent on display revenues. The Web
giants already have a history of under-performing compared to average industry growth, which was 25 percent in the third quarter. During the same period, Yahoo delivered 16 percent growth, while
AOL reported a comparatively dismal 10 percent. A downward trend "is already starting to emerge" at both AOL and Yahoo. That may be true, but third-quarter revenues didn't take into consideration the
ad network acquisitions both companies made recently, which could help spur growth in the near future.
Google, MySpace and Facebook would be less affected by a recession. Respectively, the companies delivered 62 percent, 135 percent and 200 percent growth in the third quarter. In general, Web advertising, which is still much cheaper than traditional advertising, should benefit from the continued shift of spending to the Web. Indeed, that shift might even be accelerated by a recession.
