Figures showed that an extra 338,000 subscribers have signed up to Sky services in the United Kingdom over the previous year, helping United Kingdom revenues go up by four per cent to £6.4 million.
European broadcaster Sky Plc (LON:SKY) saw its bottom line hit again by the big hike in Premier League football costs, although revenues and subscribers continue to rise. EBITDA declined by 6% to £1.525 billion.
"HBO and Sky have for many years shared a common creative culture and a common vision for the development of high quality drama", added Jeremy Darroch, Group CEO of Sky. The company now boasts 22.4 million customers.
In its home United Kingdom market, Sky said it had outperformed a weak advertising environment and declared itself to be "pleased with the initial response" to its recent entry into the United Kingdom mobile phone market.
Overall, group revenue rose by 11pc or 5pc at constant currency rates.
Sky also entered the mobile market in January with a range of SIM-only deals and more recently starting offering handsets - and giving customers the ability to upgrade after 12 months.
Media group Sky has announced a multi-year $250m (£195m) co-production deal with USA television network HBO. Going into production later this year, users will be able to virtually visit the Natural History Museum, with Sir David Attenborough as their guide.
The company said that more than 100,000 new customers had joined in the most recent quarter, with 769,000 added in the previous year, taking the total customer base to 22.4 million.
This, it said, is despite the fact that most consumer businesses face a more "challenging environment" in the first three months of a new calendar year.
Pitches are being invited from production companies around the world and the partners say they expect to green-light at least two drama projects per year with the first project coming to screen in 2018.
Media tycoon Rupert Murdoch's Fox announced in December a deal to buy the 61-per cent stake in Sky it did not already own for £11.7 billion.
