Disney said to be nearing a deal with 21st Century Fox

Under the terms of the talks, Disney would buy big parts of Fox's empire in an all-stock transaction, including its movie and television studios

The Walt Disney Company is in advanced discussions to buy significant parts of 21st Century Fox, the media company run by the Murdoch family, people briefed on the matter said on Tuesday.

And a deal between the two companies could end up splitting up the Murdochs as an operating team, with James Murdoch potentially leaving his father and brother to work at Disney.

Fox is also in negotiations with Comcast, but the talks with Disney are moving faster, these people said. An agreement with Disney could be announced as soon as next week, these people added, speaking on the condition of anonymity
