The subscription service is growing, but not as Microsoft hoped for.

Some subscriber growth data for Xbox Game Pass were revealed today in a new financial filing by Microsoft. According to the filing, growth of Xbox Game Pass subscribers has been slower than what Microsoft hoped for over the past 12 months.

According to the document, Xbox Game Pass subscriber growth was up 37% for the 12 months ending on June 30th. However, Microsoft apparently had a growth goal for that time period of 48%.

Last year, for the period running from mid-2010 through mid-2020, Microsoft saw an increase of Game Pass subscriptions of 86%, which was well above their growth goal of 71%.

Though we see these percentages, we don't actually know how many Xbox Game Pass subscribers there are. Microsoft just doesn't share that data with anybody. The last we knew, which was January 2020, Game Pass had hit 18 million subscribers.

At present, Microsoft offers Xbox Game Pass for their Xbox consoles and for PC. Individual subscriptions go for $10 per month with an Xbox Game Pass Ultimate going for $15 a month that lets you use Game Pass on both consoles and PC. Speaking of which, Microsoft recently talked about some of the big games coming to Game Pass over the next few months. You can read all about those in the story about the upcoming Xbox Anniversary Celebration.
