Aviva Premiership rugby union will be broadcast on BT Sport for at least the next six seasons, it has been announced.
BT Sport has agreed a four-year extension to its current TV deal, meaning top-tier rugby will remain on the pay-TV service until the end of the 2020-21 campaign.
The deal includes live broadcast rights for up to 80 live matches per season from 2017-18, plus extended highlights for all 135 games per season from 2015-16.
BT Sport will also show the entire Singha Premiership Rugby 7s Series until the end of 2020-21, and continue to air midweek preview and review shows.
Mark McCafferty, Chief Executive of Premiership Rugby, said BT Sport has been "a fantastic partner" for English club rugby over the past two seasons.
As such, he said the league is "delighted" to agree the longest TV agreement in the history of Premiership Rugby.
"In the 18 months we have been on-air with [BT Sport] our live TV audiences have grown by 50 per cent so it is clear that the partnership is going from strength to strength," Mr McCafferty stated.
"Their innovative style has received great acclaim and we look forward to developing the partnership over the next six seasons."
He claimed that Aviva Premiership Rugby is "in great health", with a number of new commercial partners on board.
Mr McCafferty added that it is "testimony to the strength of the competition and its clubs" that the TV deal has been renewed more than two years before the current arrangement ends.
John Petter, Chief Executive at BT Consumer, said the broadcaster is "absolutely delighted" to extend its partnership with Premiership Rugby.
"2015 will be an amazing year for rugby in the UK and the popularity of rugby will continue to grow," he stated.
"We’re delighted to be a part of this and that our customers can look forward to another six seasons of the Aviva Premiership on BT Sport.”
