The agreement enables Sky to offer exclusive coverage of the inaugural Dublin Super Cup on July 30 and 31 at the Aviva Stadium, featuring the first team squads of Manchester City, Inter Milan and Celtic, along with a League of Ireland XI. The deal runs until 2013.
Each year, the cup is guaranteed the participation of a top English Premier League club, Spanish La Liga team or Italian Serie A side, and a team selected from the best players from Ireland's top domestic league.
Sky Sports will broadcast standard and high definition coverage of the cup, along with offering a world feed for international viewers.
Barney Francis, the managing director of Sky Sports, said: "The Dublin Super Cup will be part of our summer of live football on Sky Sports. We look forward to showing three of the best-known teams in Europe and the finest Irish talent in four live matches."
Endemol Sport managing director Gregg Oldfield added: "This multi-year partnership will see the Dublin Super Cup become a landmark in Sky Sports' live summer football output.
"We are extremely proud to be joining forces with Sky and bringing a brand new, world class football tournament to one of the world's leading sports broadcasters."
The launch of the annual Dublin Super Cup follows a ten-year deal agreed last year between Endemol Sport and The Football Association of Ireland (FAI).
Alongside the Sky Sports deal, Endemol Sport said that it is finalising agreements with other broadcasters around the world, with a view to bringing live coverage of the cup to more than 100 territories across Asia, the Middle East, Europe, Africa and the Americas.
