The unveiling, at a one-day meeting with investors in New York, followed the company's recent disclosure to securities regulators that the publishing unit would book an impairment charge of up to 1.4 billion US dollars this quarter before being spun off as a separate, publicly traded company.
The logo, in cursive lettering, is based on the handwriting of founder Rupert Murdoch and his father. It replaces the striped globe of the current News Corp brand.
Since the split was announced last June, News Corp's stock has climbed 65%. The Standard&Poor's 500 Index has risen 26% over the same period. Many investors believe the struggling newspaper company will no longer be a drag on growth of the entertainment businesses.
On Tuesday, the chief executive of the publishing group, which will continue to be called News Corp, touted the unit's future as a separate entity while acknowledging its difficulties as print advertising continues to decline across the industry.
Mr Murdoch did not hold out hope for an advertising turnaround for print newspapers, whose ad revenue has been siphoned off by web-based companies such as Google and Facebook.
"We're being very realistic and not expecting any big expansion," he said. "There's no doubt the internet has taken a lot of business."
The investor day was meant to reassure investors about the value of the new News Corp. It will contain the company's newspapers in the US, Britain and Australia; Dow Jones&Co, which owns the Wall Street Journal; its for-profit education business, Amplify; book publisher HarperCollins; and TV assets in Australia.
A separate company, to be called 21st Century Fox, will house its 20th Century Fox movie studio, TV channels such as Fox News and Fox Sports 1 and its investment in overseas TV providers such as Sky Deutschland and Sky Italia. The entertainment company's logo, featuring Hollywood-style spotlights, was unveiled earlier this month.
