Link to Articles for news sites in Google SERPs

[seoFan21]

I'm trying to figure out why when I search for "international news" or "world news", for example, some sites in the SERPs have links to news articles, while others don't.  For "international news", result of Fox News and New York Times have links to articles, while CNN (the top result), only have sitelinks.   I would appreciate any theories on why this happens.  Thanks.

I see news stories rather than sitelinks for CNN.

Are your results personalized, or depersonalized? Did you pray to Google this morning, or make a disparaging remark about Matt Cutts's cat?
