The Economist notes the rise of online advertising

The Economist commented today on Google's introduction of new forms and types of online advertising. They spend a lot of the article talking about the new types of advertising Google is allowing, but never quite gets to one of the most important differentiators of online: it's a measurable medium. With our latest data showing the marketing measurement increases executive satisfaction by 10%, to say nothing increasing average budget sizes, it's no wonder online advertising is getting traction.
