SCO UNIX
SCO : Santa Cruz Operation(思高集团的前身)
SCO Group : 思高集团
自Unix系统实验室被AT&T卖给了Novell公司后,Novell公司为避孕法律纷挣,他把自己的Unix改名为Unixware.同时将Unix商标赠送给X/Open── 一个由众多Unix厂家组成的联盟,这样这个联盟内的所有成员均可使用Unix商标.
从此以后,Unix便不再是专有产品了.但后来Novell由于自身的经营问题,只能将Unixware卖给SCO公司.
八十年代初,微软与SCO合作开发发行的XENIX. 又一说,SCO的前身是由微软XENIX开发部独立出来的.
此后,SCO公司将SVR3移植到386上,并将其命名为SCO UNIX.

本月初(编者注:时为2003年11月)，当Novell宣布以2.1亿美元收购SuSE时，SCO首先站出来反对，其表示这一合并违反了SCO与Novell之间签署的一项非竞争协议。据SCO公司的总裁兼首席执行官达尔-麦克布莱德(Darl McBride)表示，Novell在上述协议中明确同意其将不与SCO公司的Unix业务竞争，签署这一协议时Novell把其在Unix系统中拥有的V源代码版权出售给了SCO的前身Caldera公司。
