research division (Bell Labs), part of AT&T Technologies
During this term, Bell Labs developed many technologies that are crucial for today's computing. For instance, transistor, Unix, C, C++, AWK, Plan 9.
On September 30, 1996 Bell Labs was divested into…

Lucent
>This same linguistic root also gives Lucifer, "the light bearer" (from lux, 'light', and ferre, 'to bear'[5]), who is also a character in Dante's epic poem Inferno. Shortly after the Lucent renaming in 1996, Lucent's Plan 9 project released a development of their work as the Inferno OS in 1997.[4][6] This extended the 'Lucifer' and Dante references as a series of punning names for the components of Inferno - Dis, Limbo, Charon and Styx (9P Protocol). When the rights to Inferno were sold in 2000, the company Vita Nuova Holdings was formed to represent them. This continues the Dante theme, although moving away from his Divine Comedy to the poem La Vita Nuova.
>In 1997, the smallest then-practical transistor (60 nanometers, 182 atoms wide) was built. In 1998, the first optical router was invented.
>2000 was an active year for the Laboratories, in which DNA machine prototypes were developed; progressive geometry compression algorithm made widespread 3-D communication practical; the first electrically powered organic laser invented; a large-scale map of cosmic dark matter was compiled, and the F-15 (material), an organic material that makes plastic transistors possible, was invented.
>Lucent was merged with Alcatel SA of France in a merger of equals on December 1, 2006, forming Alcatel-Lucent.[2]

Alcatel-Lucent
>On 28 August 2008, Alcatel-Lucent announced it was pulling out of basic science, material physics, and semiconductor research, and it will instead focus on more immediately marketable areas, including networking, high-speed electronics, wireless networks, nanotechnology and software.[25]
Alcatel-Lucent was absorbed by Nokia in January 2016.
