"So far we've found that the speed and visual nature of the service encourages readers to look at many articles and, for the ones that catch their interest, click through to the story publishers' websites," explains the Google News blog.
Unlike Google News, which only shows a small snippet from the article, Fast Flip displays a screenshot that includes the first paragraphs of the article. That means Google needs to get permission from each news site before adding it to Fast Flip. If the experiment is successful and Fast Flip makes news articles more discoverable, it could replace Google News image view.
