The BBS collective produced three notable underground paths - the first was based around the exchange of h/p/a information in the form of text files and ascii diagrams, the second was based around minors trying to shuffle around porn from Adult pay-BBS systems and the last and most interesting, the warez scene produced a number of offshoots - the demo scene, the crack scene, the ansi art scene and the tracking scene, some of which produced scenes of their own.
