Proprietary software From Wikipedia, the free encyclopedia Proprietary software, also known as non- free software, is computer software for which the software's publisher or another person reserves some rights from licensees to use, modify, share modifications, or share the software. It sometimes includes patent rights.

Proprietary software is usually created by businesses who want to sell their software, but some programs that are free to use are still proprietary because the user is not allowed to change them. With proprietary software, only the people that make the software can see and change the code.
From Wikipedia, the free encyclopedia This is a list of proprietary source-available software, which has available source code, but is not classified as free software or open-source software. In some cases, this type of software is originally sold and released without the source code, and the source code becomes available later.
From Wikipedia, the free encyclopedia This is a list of notable software packages which were published under a proprietary software license but later released as free and open-source software, or into the public domain. In some cases, the company continues to publish proprietary releases alongside the non-proprietary version.

Proprietary software, also known as non-free software, or closed-source software, is computer software for which the software's publisher or another person restrict's the user's freedom to run, edit, contribute to, or share the software. It may restrict patent rights.

Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors usually provided the source code for installed software to customers. Customers who developed software often made it available to others without charge.Closed source means computer programs whose source code is not published. It is available to be edited only by the organization by which it is developed. In 1969, IBM, which had antitrust lawsuits pending against it, led an industry change by starting to charge separately for mainframe softwareand services, by unbundling hardware and software. Bill Gates' "Open Letter to Hobbyists" in 1976 decried computer hobbyists' rampant copyright infringement of softw...
The owner of proprietary software exercises certain exclusive rightsover the software. The owner can restrict use, inspection of source code, modification of source code, and redistribution.
Proprietary file formats and protocols
Proprietary software often stores some of its data in file formats which are incompatible with other software, and may also communicate using protocols which are incompatible. Such formats and protocols may be restricted as trade secrets or subject to patents.
A proprietary application programming interface (API) is a software library interface "specific to one device or, more likely to a number of devices within a particular manufacturer's product range." The motivation for using a proprietary API can be vendor lock-inor because standard APIs do not support the device's functionality. The European Commission, in its March 24, 2004 decision on Microsoft's business practices, quotes, in paragraph 463, Micr...
A dependency on the future versions and upgrades for a proprietary software package can create vendor lock-in, entrenching a monopoly position.
Proprietary software which is no longer marketed, supported or sold by its owner is called abandonware, the digital form of orphaned works. If the proprietor of a software package should cease to exist, or decide to cease or limit production or support for a proprietary software package, recipients and users of the package may have no recourse if problems are found with the software. Proprietors can fail to improve and support software because of business problems. Support for older or existing versions of a software package may be ended to force users to upgrade and pay for newer versions (planned obsolescence). Sometimes another vendor or a software's community themselves can provide support for the software, or the users can migrate to either competing systems with longer support life cycles or to FOSS-based systems. Some closed-source software is released by their owner at end-of-life as open-source or source avail...
Some formerly open-source software was made proprietary later. Sometimes for commercialization reasons, sometimes as security or anti-cheat measurement (Security through obscurity). A famous example of such is the Doom source port ZDaemon which was prone to aimbotcheaters.
Proprietary software is not synonymous with commercial software, although the two terms are sometimes used synonymously in articles about free software. Proprietary software can be distributed at no cost or for a fee, and free software can be distributed at no cost or for a fee.The difference is that whether or not proprietary software can be distributed, and what the fee would be, is at the proprietor's discretion. With free software, anyone who has a copy can decide whether, and how much, to charge for a copy or related services. Proprietary software that comes for no cost is called freeware. Proponents of commercial proprietary software argue that requiring users to pay for software as a product increases funding or time available for the research and development of software. For example, Microsoftsays that per-copy fees maximise the profitability of software development. Proprietary software generally creat...
Examples of proprietary software include Microsoft Windows, Adobe Flash Player, PS3 OS, iTunes, Adobe Photoshop, Google Earth, macOS (formerly Mac OS X and OS X), Skype, WinRAR, Oracle's version of Java and some versions of Unix. Software distributions considered as proprietary may in fact incorporate a "mixed source" model including both free and non-free software in the same distribution. Most if not all so-called proprietary UNIX distributions are mixed source software, bundling open-source components like BIND, Sendmail, X Window System, DHCP, and others along with a purely proprietary kerneland system utilities. Some free software packages are also simultaneously available under proprietary terms. Examples include MySQL, Sendmail and ssh. The original copyright holders for a work of free software, even copyleft free software, can use dual-licensing to allow themselves or others to redistribute propriet...
Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing the software, and this results in reliance on the publisher to provide updates, help, and support.
