21st Century Fox has made a bid to acquire the 61% stake it doesn't already own in Sky for £18.5 billion.
The offer is still subject to approval by Sky's current shareholders who would receive £10.75 for each share under the terms of the deal.
21st Century Fox is the founding shareholder of Sky and this combination will create a global leader in content creation and distribution as well as enhance the firm's sports and entertainment scale.
The acquirer entered into a bridge credit agreement with Goldman Sachs Bank USA, Deutsche Bank Securities and JPMorgan Chase Bank to finance the acquisition.
Deutsche Bank is acting as financial adviser to 21st Century Fox.
The acquisition is expected to complete before the end of 2017.
Rupert Murdoch (Fox's owner) had previously made an attempt to acquire the company in 2011, but the bid was derailed by the UK phone hacking scandal.
