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.
