Google owns nearly 80% of ad space
It's all over the Internet right now that Google has almost 80% of Search Advertising in the US. This may not look good for them now that they are attempting to look less like the monopoly that Yahoo is making them out to be. But for those looking to advertise online, this goes to prove that Google is the place to do it. The other ad carriers do have something to offer but until we have at least a 50/50 split between Google and Yahoo, like in Japan, then most of your eggs should be in the Google basket.
