Today, FreeBSD is used by many IT companies such as IBM, Nokia, Juniper Networks, and NetApp to build their products. Certain parts of Apple's Mac OS X operating system are based on FreeBSD. Both the PlayStation 3 and Nintendo Switch operating system also borrow certain components from FreeBSD, while the PlayStation 4 operating system is derived from FreeBSD 9. Netflix, WhatsApp, and FlightAware are also examples of large, successful and heavily network-oriented companies which are running FreeBSD.
