"Comcast is interested in the same set of assets that Disney approached Fox about earlier this year", notes the outlet.

A week after reports of interest from Walt Disney Co in buying out much of Rupert Murdoch's USA film and television empire, the sources hinted at the prospect of a battle between other media suitors for the assets. The NBCUniversal parent is also eyeing Fox's movie studio, cable networks and its regional sports network.
