First came the damning revelations, the reader boycotts, the police investigation, and the news of U.K. advertisers pulling ads from News of the World. Now, the repercussions from the News Corp. phone hacking scandal are spreading to the U.S., where some ad buyers are getting twitchy.

The scandal has buyers trying to reconcile the outrageousness of the charges surrounding Rupert Murdoch’s U.K. tabloid with News Corp.'s significant U.S. footprint, which includes Fox News as well as the straitlaced Wall Street Journal. Some said that while they haven’t suspended advertising in News Corp.’s U.S. properties, they're growing wary about doing business with the media giant.
