Sky’s UK broadband network has crossed the 1 Terabit threshold for the first time.
This means the network has delivered 1,000 gigabits of data a second - equivalent to half a million simultaneous viewings of a Sky Movies film online.
Sky said the figures show that an increasing number of its 4.4 million customers are making the most of unlimited broadband packages.
The firm explained that internet subscribers are able to stream movies, download music and play games online without being slowed down by traffic shaping.
Lyssa McGowan, Director of Communications Products at Sky, said it is a reflection of the way people use the internet today that Sky has reached the 1TB network milestone.
"Over recent years, data consumption has grown exponentially," she stated.
"Thanks to home Wi-Fi, we’re now seeing several people online at the same time in the same home - whether that’s at their PC or laptop or, latterly, browsing on their tablets and smartphones while watching television."
Ms McGowan said this has come at the same time as an explosion in online video, online gaming and, in particular, TV on-demand.
She noted that viewers are commonly watching content via an internet connection, with more and more of it in high definition.
"This level of data traffic explains why households want the peace of mind of totally unlimited broadband, with no risk of exceeding download limits, while a growing number want the super-fast speeds fibre provides," Ms McGowan added.
She said Sky is supporting this trend through the launch of "innovative services" like Sky Go.
"That’s why our cutting-edge broadband network has been built with video in mind," Ms McGowan claimed.
