From 1994 to 1995, WADs were primarily distributed online over bulletin board systems or sold in collections on compact discs in computer shops, sometimes bundled with editing guide books. FTP servers became the primary method in later years. A few WADs have been released commercially, including the "Master Levels for Doom II", which was released in 1995 along with "Maximum Doom", a CD containing 1,830 WADs that had been downloaded from the Internet. The "idgames" FTP archive contains more than 18,000 files, and this represents only a fraction of the complete output of "Doom" fans. Third-party programs were also written to handle the loading of various WADs, since all commands must be entered on the DOS command line to run. A typical launcher would allow the player to select which files to load from a menu, making it much easier to start. In 1995, WizardWorks released the "D!Zone" pack featuring hundreds of levels for "Doom" and "Doom II". "D!Zone" was reviewed in "Dragon" by Jay & Dee; Jay gave the pack 1 out of 5 stars, and Dee gave the pack 1½ stars.
