new American Bell Advanced Information System's "Globe" logo. In 1984, the American Bell Advanced Information Systems name was changed to AT&T Information Systems. Logo The AT&T Globe logo, originally designed by Saul Bass and sometimes informally called the "Death Star" for its visual similarity to the weapon of that name in the Star Wars movie franchise, originated for use with American Bell. When Judge Greene banned AT&T from using any Bell marks whatsoever after the breakup, except for usage of the Bell Labs name, AT&T switched over to the Globe logo. Post-breakup Since AT&T was required to divest the Bell logo and trademark to the Baby Bells, American Bell was renamed AT&T Information Systems on January 1, 1984. The business unit, American Bell Advanced Information Systems, was absorbed into AT&T Network Systems, while American Bell Consumer Products, renamed AT&T Consumer Products, became a unit of AT&T Technologies. AT&T Information Systems held its status as separate from any other AT&T company until 1986, following several FCC decisions which loosened restrictions set before the breakup. It was completely absorbed into American Telephone and Telegraph Company in 1989.
