They do this, first, because the internet, in effect, eliminates scarcity in the medium. There are as many web pages for advertisers as there are keywords that can be typed into a search engine, situations that game players might find themselves in, and so forth. Each one comes with its own context, and almost every context suits some product. The second reason is that if you can track the success of advertising, especially if you can follow sales leads, then marketing ceases to be just a cost-centre, with an arbitrary budget allocated to it. Instead, advertising becomes a variable cost of production that measurably results in making more profit.
