Commercial softwar
Commercial software, or less commonly, payware, is computer software that is produced for sale or that serves commercial purposes.
Commercial software is most often proprietary software, but free software packages may also be commercial software.[]
All or parts of software packages and services that support commerce are increasingly made available as free software[citation needed]. This includes products from Red Hat, Apple Computer, Sun Microsystems, Google, and Microsoft Corporation. Microsoft Corporation uses "commercial software", to describe their business model.
