The BBC has reported that the Xbox Series X/S launch has caused record broadband data usage in the UK. The matter was only elevated due to a Call of Duty: Modern Warfare and Warzone update, which rested at 65GB in size - we reported on the contents of the update a few days ago.
Since the Xbox Series X/S launch was the first public experience of next-gen, a large amount of big titles also hit shelves that day, including Destiny 2: Beyond Light and Assassin's Creed Valhalla, plus even moreso, the Call of Duty: Black Ops Cold War pre-loads for next-gen were available.
Looking solely at those four titles, and not counting the many others of which were part of Xbox's launch line-up, approximately 360GB of content would be downloaded. Network providers managed to handle the strain on their systems, however, next-week the PlayStation 5 will release in Europe, meaning broadband data usage will once again go through the roof, as masses download next-gen software to their new console.
