Formula One's future on terrestrial television appears all but over after Sky Sports announced it has agreed an exclusive contract to broadcast the sport from 2019.
Channel 4, new to the grid this season after the BBC surrendered its deal three years early, currently shares the broadcasting rights with Sky.
But its time in the sport looks set to be short-lived with Sky agreeing a six-year contract to be the exclusive rights-holder in the UK.

While Sky has said that the British Grand Prix, as well as highlights of the other races, will be shown on a 'free-to-air' basis, the news is likely to come as huge blow to the millions of fans who watch the sport on terrestrial TV.
Nearly three million people tuned in to watch Channel 4's highlights of Sunday's season-opening Australian Grand Prix on Sunday.

'I am delighted that we will continue to work together,' said Bernie Ecclestone, the sport's chief executive of Formula One Management's new deal. 'Sky's commitment to the sport and standard of coverage is second to none.'
Barney Francis, managing director of Sky Sports, added: 'This is a brilliant deal that takes Sky's partnership with F1 to the next level. Since 2012, we have demonstrated unrivalled commitment to F1, offering fans innovations including a dedicated channel and the very best broadcasting talent.
'We are delighted that we are strengthening our coverage for viewers even further, with live and exclusive F1 from 2019. We are pleased to support F1 and look forward to working with them to progress, develop and enhance coverage of the championship during the agreement.' 
As well as making the British Grand Prix available for free, Sky will also show highlights of qualifying and races without charge.

Sky Sports entered Formula One in 2012 and signed a seven-year agreement which saw it share the rights with the BBC.
It marked the first time the sport had not been broadcast exclusively on terrestrial television in Britain.
The subscription channel continued its deal alongside the BBC until the end of last season before the latter was forced to pull the plug on its contract in a bid to make a £35million cut to its sports budget.
Channel 4's deal will see it show 10 races live - without commercial breaks - and screen extensive highlights of the other races.
