Today's newsstands don't sell a broom, the price of Internet advertising has plummeted and newspapers earn less from advertising than they did forty years ago.

When you search for "running shoes store" in Google you are looking for a running shoes eCommerce, while when you open the newspaper El mundo, whether digital or paper, what you are looking for is news. Trying to catch your eye with a running store banner or steal your page is much less efficient because it wasn't what you were looking for.
