NEW YORK - Rupert Murdoch's News Corp. made an unsolicited offer yesterday to buy Dow Jones & Co. for $5 billion, but the deal, which would add the

to Murdoch's global media empire, faces doubtful prospects since the controlling shareholders of Dow Jones said they would vote against it.

The offer of $60 per share represents a huge premium of about 65 percent over Dow Jones' closing share price on Monday. However, Dow Jones said yesterday that the Bancroft family, the company's controlling shareholders, said they would reject the deal.
