How do these news web-crawlers thrive?

What is the business model for all these web crawlers which fetches the top news from blogs / news websites and display? Do they thrive only on the revenues from ads (or) is there any other means of earning profits ??

The main goal of the news web-crawlers isn't to turn a profit, instead they are doing their thing to provide search engines with the most accurate and recent news in the search results.
