Add EULA for registered Doom and info about the DUL
copy of DOOM right now and you will be safe from our wrath.
After the success of Doom, [[Id id Software]] gave [[Frans P. de Vries]], the then-[[Idgames idgames archive]] maintainer, permission to upload the alphas and press release due to their historic interest.
=== Shareware episode ===
The episode ''[[Knee-Deep in the Dead]]'' was released as [[shareware]] on the [[Wikipedia:{{wp|University of Wisconsin}} {{wp|University of Wisconsin]] [[Wikipedia:File Transfer Protocol|FTP]] }} server on [[Timeline#1993|December 10, 1993]]. === EULA === The registered version of Doom was under a standard end-user license agreement between the purchaser and id Software, limiting rights to copy, distribute, reverse engineer, and to some extents modify the program. === Data Utility License === id Software introduced the [[Data Utility License]] in 1994 in an effort to protect themselves from possible issues that they felt might arise in the then-nascent editing community. Several prominent [[editing utility]] authors were asked to sign this agreement and to enforce some of its terms in turn on their end users.
=== Doom II ===
[[Doom II]] was the first traditionally commercial release of doomDoom. It was first sold boxed in high street stores on [[Timeline#1994|September 30, 1994]] and no shareware or demo version was released.
=== Source code release ===
After the loss of the source code for the [[glDoom]] [[source port]] in 1998 due to a hard drive crash, some people, including [[John Carmack]], suggested that if the author had been required to distribute the changes he made to the code, then it would have been more likely that others would have had copies of the source. As a result, id Software re-licensed the source code for Doom under the terms of the {{wp|GNU General Public License|GPL}} on [[Timeline#1999|October 3, 1999]]. Many existing source ports followed suit by obtaining permission from their copyright holders to re-license their work.
