Sky is to launch a new TV channel that will make live games including Premier League matches available to non-sports subscribers for the first time. The new channel, Sky Sports Mix, is aimed at encouraging a higher proportion of the broadcaster’s 12 million-plus subscribers to add its sports packages to their monthly TV plan. About 5 million to 6 million Sky customers have a sports package, which costs about £25 a month, with subscribers on the cheapest tier paying about £20.
