LONDON — HBO and pay TV operator Sky have extended their existing deal, which covers the U.K. and Ireland, to include Germany, Italy and Austria.

The new agreement means that Sky will have the exclusive rights to broadcast first-run HBO shows in Germany, Austria and Italy until 2020, bringing those markets in line with the U.K. and Ireland. The shows will air on Sky’s premium channel Sky Atlantic; where possible, episodes will air simultaneously with the U.S. The pact also makes more HBO content available via its on-demand platforms.

The agreement is the first content deal covering all Sky territories in Europe that it has negotiated.

For the first time, all the episodes of current seasons of shows like “True Detective” will be available to view on catch up as the season transmits. As well as watching the shows on TV sets subscribers can watch them on the mobile TV service Sky Go, via streaming and download. Once downloaded, content is available on devices for 30 days, and for 48 hours after start of viewing.

Customers who use Sky’s streaming platforms NOW TV and Sky Online will also have access to episodes of HBO shows on demand.

Gary Davey, managing director, content, at Sky, commented: “Sky and HBO share many common values, as well as a passion for high-quality television like ‘Game of Thrones’ and ‘Veep.’ Our partnership, in its sixth year, now escalates to a whole new level. HBO has an amazing slate planned for 2016 including ‘Vinyl’ and ‘Westworld,’ but it will also see the premiere of our first co-production together, the ‘Young Pope,’ starring Jude Law.”

Sky, which has 21 million subscribers across Europe, has a combined programming budget of £4.9 billion ($7.44 million) a year.
