21st Century Fox
21st Century Fox is the media and entertainment company that has been formed following News Corporation's separation into two distinct publicly-traded companies.
News Corporation and its subsidiary Sky Italia have been partners in Team Sky since the team first raced in 2010. The partnership will extend and increase this support for the team, which will continue to be known as Team Sky.
Sir Dave Brailsford, Team Principal of Team Sky, said: "We're excited to have this long-term commitment and to welcome 21st Century Fox on board.
"It feels like great recognition of the strength and value of the partnerships we've developed. 21st Century Fox is a perfect fit and is an appealing global brand that will be great to work with.
James Murdoch, News Corporation's Deputy Chief Operating Officer, said: "It's a great time to increase our commitment to Team Sky and to add the support of an exciting new entertainment brand. We're proud of the team's success so far, its professionalism and its approach to attracting new fans to the sport and increasing grassroots participation in cycling."
