Freeware
Freeware refers to proprietary software distributed without cost to users, though its usage terms vary significantly across publishers. Unlike free and open-source software, freeware typically doesn't include access to source code. Publishers establish their own licensing terms - some permit modification or redistribution while others restrict such activities.
This model often serves commercial purposes, such as promoting premium versions (freemium) or encouraging paid upgrades (shareware). The absence of standardised licensing distinguishes freeware, with each developer defining their own distribution and usage policies.
History[edit]
The concept of freeware originated in 1982 when Andrew Fluegelman introduced the term while distributing his communication software PC-Talk through non-commercial channels, adopting a shareware-like distribution model. Historically during the 1980s-90s, freeware primarily referred to software distributed without its source code. Notably, freeware remains adaptable - its classification can evolve into shareware or other models based on distribution changes.
