Guardian: Sky has unveiled a new premium set-top box and “best of the web” streaming service as it looks to keep apace with viewers attracted to new TV services including Amazon, Apple and Netflix. Sky said that the new service, called Sky Q, is arguably the biggest product innovation since it launched the Sky+ box back in 2001. Sky Q, which will launch next year, will allow viewers to watch shows on up to five different screens and has five times the amount of program storage capacity of its current set-top box.
