Fox could face further competition from the U.S. cable giant Comcast, however, after it forced Sky's independent directors to drop their previous backing for Fox with an unexpected £12.50-a-share bid for the group in February.
Murdoch's company still faces significant regulatory battles in Britain, including the culture secretary's statement that Fox would have to divest itself of Sky News to win government approval because of concerns about media plurality.
"American consumers have benefitted from head-to-head competition between Disney and Fox's cable sports programming that ultimately has prevented cable television subscription prices from rising even higher", said Makan Delrahim, assistant attorney general and head of the Justice Department's Antitrust Division.
Fox has increased its bid by just over 30% since its first offer in December 2016. 21CF now anticipates that the acquisition will complete in the third quarter of 2018.
According to The Hollywood Reporter, an executive for 20th Century Fox has filed a lawsuit to put a stop to the sale of 21st Century Fox's studio assets to Disney, which he claims violates securities rules.
"We strongly believe that a combined 21CF and Sky will be a powerful driver for the continued growth and vibrancy of the United Kingdom and broader creative industries. The enhanced scale and capabilities of the combination will enrich Sky's ability to continue on its mission for years to come, especially at a time of dynamic change in our industry".
"We have long recognised the unique position that Sky occupies", said Gilbert. Since then, Variety reports that Disney has ramped up its efforts, countering with an unprecedented $71.3 billion deal.
Sky's independent directors accepted the latest Fox offer.
Rupert Murdoch's company further added that Disney has provided its consent to the increased debt that would be incurred by 21CF as a result of the increased Sky offer.
Only this time, it's not Comcast standing in the Mouse House's way, but a shareholder named Robert Weiss, who recently filed a lawsuit to stop the historic Disney-Fox merger.
