This week, Microsoft announced an expansion of the functionality of Cortana with the Cortana Skills Kit and Cortana Devices SDK that will dramatically expand the places we will find the AI assistant. In the press release, the company also stated that there are more than 145 million monthly active users of Cortana and on the surface, this seems impressive, but digging in a bit reveals there is more to the story.
For starters, we can get a small glimpse of the growth the platform is experiencing as Microsoft said in July of 2016 that there were 100 million monthly active users (MAU) of Cortana. Doing simple math, we can see that Cortana has added 45 million MAUs in about six months. Notably, during this period, the Anniversary update was released to consumers but it’s not immediately clear if this release encouraged more users to try out Cortana or it’s simply coincidental of the growth and release of a major update to Windows 10.
