The takeover battle for Sky pits two dynastic titans of world media against each other head to head.
Billionaire Brian Roberts, 58, is chairman and chief executive of Comcast — the business founded by his father Ralph in 1963 — and controls a third of the shares. The father of three is also a top squash player with a gold medal and four silvers at the Maccabiah Games in Israel, known as the Jewish Olympics. He is taking on another billionaire, 86-year-old media mogul Rupert Murdoch, who is still co-executive chairman, alongside son Lachlan, of 21st Century Fox.
Another son, James, is chief executive of the company that owns the film and TV operations of the Murdoch family empire. Caught in the middle is Jeremy Darroch, chief executive of Sky since 2007.
The struggle for control of Sky involves the employers of the some of the biggest names in television on both sides of the Atlantic.
Comcast owns the NBC network whose best known presenters include Today show anchors Hoda Kotb and Savannah Guthrie, and NBC Nightly News anchor Lester Holt.
Familiar Fox faces include news anchor Martha MacCallum and Fox News Sunday presenter Chris Wallace, while Sky News is fronted during the week by Kay Burley, in the mornings by Sarah-Jane Mee and at night by Dermot Murnaghan.
