This means more than half of all Sky TV subscribers can now stream content over the web to their main television set.
"Our focus in the last 12 months has been on driving take-up and usage of connected TV services to enable more customers to benefit from a much richer entertainment experience," Sky stated.
"The investment we have made to put Sky at the heart of the ‘connected home’ has delivered results."
Sky said the rapid roll-out of connected TV has driven a threefold increase in on-demand viewing.
The service provider claimed its expanded Box Sets offering has proved "particularly popular".
"Box Set usage grew rapidly throughout the year to hit 86 million downloads in Q4 2014, a fourfold increase year-on-year," Sky noted.
"With more than 250 Box Sets now available on Sky and more of the latest titles than anyone else in the market, titles like '24' and 'Grey’s Anatomy' achieved over ten million downloads each.""
