Sky's new Go service has been formally launched.
First announced last month, Sky Go allows its existing subscription customers to watch live TV across a range of mobile devices.
Sky Go enables customers to watch content from laptops, PCs and Macs and, rolling out in time for the beginning of the Premier League football season, from the iPhone, iPad and iPod Touch.
On laptops and computers customers have access to more than 30 live channels, including all five Sky Sports channels, Sky Movies, Sky News, Sky 1, Sky Atlantic and Sky Arts.
Customers with iPhones, the iPod Touch and iPad, have access to all five Sky Sports channels, ESPN and Sky News. More channels will be added over time, Sky said.
Each Sky home can register up to two Go-compatible devices.
The new service will be available in August to non-Sky TV customers, with monthly subscriptions priced from £15-£40.
Sky also expects to complement Go with its recent acquisition of public Wi-Fi network The Cloud, which offers wireless access in more than 4,500 public locations - across coffee shops, hotels, restaurants and bus and train stations.
The firm has also announced a subscription price freeze across all its broadband, TV and Talk products for at least 12 months from September 1st this year.
Andrea Zappia, Managing Director of Sky's customer group, said: "We're committed to keep innovating so that our customers enjoy the best possible entertainment experience. Sky Go is just the latest example of how we're giving people a better choice of programmes combined with better ways to watch."
Ms Zappia said the decision to freeze subscription prices, benefitting all its ten million customers, was designed to help customers who are facing rising household bills.
"With subscription prices frozen for at least a year, our customers can look forward to getting more than ever from Sky," she said.
