Only three news sites - CNN, Yahoo News and The New York Times – out of 22 appeared to use high levels of ad targeting, according to a Pew Research Center study. In these cases, 45 percent or more of the ads were different from one user to the next.
Another three news sites - CBS, USA Today, and MSNBC – exhibited moderate levels of targeting where between 29 percent and 40 percent of the ads were different across users.
