US regulators have cleared Walt Disney Co's plan to buy most of 21st Century Fox, removing a final barrier to the $71.3bn (£54.2bn) deal.
The approval requires the sale of Fox's regional sports networks in the US, due to competition concerns, the Justice Department's antitrust division said.
Disney, which had signalled willingness to sell the sports networks, said it was "pleased" with the decision.
The Justice Department said without the sale of the 22 regional sports networks, the deal may have led to higher prices for cable sports watchers in local markets, where Fox and Disney currently compete.
Currently, Fox's regional sports networks have more than 60 million subscribers and local rights to a majority of baseball and basketball teams.
Disney is the owner of ESPN and other local channels.
