A demand for entertainment on the go helped BSkyB to report slightly better than expected first-quarter profits in its final results before it expands into Europe. 

Britain's dominant pay-TV provider agreed in June to pay $9 billion to buy Rupert Murdoch's Sky Deutschland and Sky Italia to take its hunt for growth abroad by creating a media powerhouse with 20 million customers. 

BSkyB has decided its future growth lies in creating a European pay-TV leader that will operate in Britain, Ireland, Germany, Austria and Italy, after encountering its toughest market conditions in its 25-year history. 

The group today posted results for the three months to the end of September showing a record 309,000 users signing up to its Sky Go Extra service.

This allows subscribers to watch programmes on phones and tablet computers when away from home. 

"The investments that we have made in new connected TV services are delivering growing benefits to our business," chief executive Jeremy Darroch said. "Our mobile TV service Sky GoExtra achieved a record quarter of growth," he added. 

After growing rapidly in the last two decades by offering premium TV channels carrying movies and sports, Sky has recently focused on selling its existing customers more services, such as broadband, as the number of those new households signing up starts to slow. 

It said today it added 46,000 net new TV customers and 75,000 newbroadband customers, lifting adjusted operating profit by 11% to £316m and slightly ahead of forecasts at £311m.
