Lucent origin and history to current day. Now part of Nokia but called Bell Labs once again.
"Significant changes occurred in 1984 when, as a consequence of a divestiture agreement with the U.S. Government, AT&T Corporation divested itself of its local exchange companies and the Bell System as it was known ceased to exist. As part of the divestiture agreement, AT&T Technologies assumed the business of Western Electric and Bell Laboratories. Concurrently, several thousand Bell Laboratories employees were split off to form Bellcore, the organization established to provide research and technical functions for the newly independent local exchange carriers.
In 1996, AT&T spun off most of Bell Laboratories and its equipment manufacturing business into Lucent Technologies, Inc. (AT&T retained a smaller number of researchers to form AT&T Laboratories.) As part of this transition, most development departments were integrated into the business divisions of Lucent Technologies in order to more effectively manage the business in what was now a competitive market. The research functions remained within Bell Laboratories. In 2007, a year after the merger of Lucent Technologies and Alcatel (forming Alcatel-Lucent), Bell Laboratories and the former Research and Innovations division of Alcatel were combined into a single organization.
2016 brought yet another consolidation, as Nokia acquired Alcatel-Lucent to create a new Nokia. Bell Labs and the former Nokia FutureWorks organization joined forces to create a larger Bell Labs, spanning more countries, yet retaining the same mission throughout its 90+ year history, to solve the great 10x industry challenges and produce disruptive innovations that improve the quality of life."
