Employees at American Bell who worked in AT&T facilities that housed Bell Labs and Western Electric offices often encountered
bureaucratic red tape, such as restrictions on using the one library in the same building because it was owned by Bell Labs.
American Bell contained two core units:
*American Bell Consumer Products - sold residential telephones/terminal equipment
*American Bell Advanced Information Systems - sold business telephone/terminal equipment, such as the
American Bell Merlin system, PCs, and mid-sized computers running on the company's proprietary
Unix operating system

.
On January 1, 1983, a year prior to the final breakup of the Bell System in 1984, American Bell Advanced Information Systems (AIS) was launched as an unregulated AT&T subsidiary with a mission to directly challenge IBM in the communications/computer space. Led by Mr. Archie J. McGill, who joined AT&T in 1973 after a rapid rise at the International Business Machines Corporation. McGill was charged with transitioning and positioning the telephone company for the era of deregulated head-to-head competition in the high-tech market. The new enterprise was introduced to the world with a splash on New Year's Eve 1983 at New York Times Square when the traditional New Year's Eve crystal countdown ball was replaced with a crystal version of the 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.
