Dow Jones said on Thursday it did not know that Nicholas Negroponte, one of the five members of an editorial committee that will act as a buffer between Rupert Murdoch and the Wall Street Journal, has received money for his foundation from News Corp.

The connection between Mr Negroponte and News Corp, one of the key corporate backers of the One Laptop per Child foundation that makes inexpensive laptop computers for poor children, goes back to at least 2005 and has often been reported on.
