Rupert Murdoch's News Corporation has confirmed it is considering plans to split the business in two.
A report earlier in News Corp-owned The Wall Street Journal said the group was looking to separate its entertainment businesses from publishing assets, including The Sun and The Times.
The move would see the group's 39% stake in broadcasting giant BSkyB separately listed from the embattled UK newspaper arm News International, which has been the focus of the phone hacking scandal that led to the closure of News Corp's News of the World tabloid paper.
In a short statement, News Corp said it was "considering a restructuring to separate its business into two distinct publicly traded companies".
Shares in News Corp jumped as much as 8% on Wall Street as investors cheered confirmation of the plans, which come after years of calls for the group to separate its publishing arm from the faster growing entertainment businesses.
In London, BSkyB shares raced 3% higher amid market speculation that the split will raise the possibility of News Corp reviving its plans to take full control of BSkyB.
It had to scrap a deal to buy the remaining stake of BSkyB in the wake of the phone hacking scandal, but a restructuring has the potential to effectively quarantine the scandal-hit papers from the rest of the group and pave the way for the deal to be resurrected.
News Corp's move would see film and television businesses - including 20th Century Fox and the Fox broadcasting network - grouped in one company.
The other company would hold all News Corp's publishing interests, such as The Wall Street Journal, The Times, The Sun, The Australian, The New York Post and publisher HarperCollins.
The entertainment arm would be by far the bigger operation, with the publishing division hindered in recent years by tough media market conditions and costs related to the UK phone hacking scandal.
