Linux adoption

Linux adoption refers to the adoption of Linux computer operating systems by households, nonprofit organizations, businesses, and governments.Many factors have resulted in the expanded use of Linux systems by traditional desktop users as well as operators of server systems, including desires to minimize software costs, increase network security, and support open-source philosophical principles. In recent years several governments, at various levels, have enacted policies shifting state-owned computers to Linux from proprietary software regimes.In August 2010 Jeffrey Hammond, principal analyst at Forrester Research, declared, ""Linux has crossed the chasm to mainstream adoption,"" a statement attested by the large number of enterprises that had transitioned to Linux during the late-2000s recession. In a company survey completed in the third quarter of 2009, 48% of surveyed companies reported using an open-source operating system.The Linux Foundation regularly releases publications regarding the Linux kernel, Linux OS distributions, and related themes. One such publication, ""Linux Adoption Trends: A Survey of Enterprise End Users,"" is freely available upon registration.
