에이티앤티(AT&T) - Hey Buddy

Western Electric was fully absorbed into AT&T as AT&T Technologies, and was divided into several units focused on specific customer groups, such as AT&T Network Systems and AT&T Consumer Products.

After its own attempt to penetrate the computer marketplace failed, in 1991, AT&T absorbed NCR Corporation (National Cash Register), hoping to capitalize on the burgeoning personal computer and UNIX networked server markets, but was unable to extract lasting financial or technological gains from the merger. After deregulation of the U.S. telecom industry via the Telecommunications Act of 1996, NCR was divested again. At the same time, the majority of AT&T Technologies and the renowned Bell Laboratories was spun off as Lucent Technologies. The industry as a whole had many other reorganizations since the 1990s, both due to deregulation and because of technological advances reducing demand and pricing power in telecommunications.
