Freeware

Freeware (portmanteau of "free" and "software") is software that is available for use at no cost or for an optional fee, but usually with one or more restricted usage rights. Freeware is in contrast to commercial software, which is typically sold for profit, but might be distributed for a business or commercial purpose in the aim to expand the marketshare of a "premium" product. According to the Free Software Foundation, "freeware" is a loosely defined category and it has no clear accepted definition, although FSF says it must be distinguished from free software (libre). Popular examples of closed-source freeware include Adobe reader and Skype.
