A formula or model of corporate logos, popoular in the
late 1980'
s after AT&T broke off from
Bell in 1982 and developed a logog that originally, was intended to reference a lighted sphere, but more closely resembled the design of the Death
Star from the Star Wars movies. The corporate logos for several companies, including NeoData, Centrobe (Now EDS) were among the slew of tech companies to adopt similar abstracted variations of this concept, and in effect, resulted in a bunch death-
star like logos. The most famous and enduring of these is AT&T's logo, of course.
