Also in January 2016, Netflix announced it would begin blocking virtual private networks (VPNs) since they can be used to watch videos from a country where they are unavailable. The result of the VPN block is that people can only watch videos available worldwide and other videos are hidden from search results, which can however be found on the Unofficial Netflix Online Global Search (uNoGS) website. At the same time, Netflix reported 74.8 million subscribers and predicted it would add 6.1 million more by March 2016. Subscription growth has been fueled by its global expansion. By the end of the year, Netflix added a feature to allow customers to download and play select movies and shows while offline.
