- A portion went to the (then) RBOCs, which became Telcordia and was eventually sold to SAIC.
- Another portion, AT&T Labs, stayed with AT&T. At present, this portion seems to have survived SBC's buyout of AT&T.
- Yet another portion, Avaya Labs, was a consequence of the Avaya was spin-off.
- The remaining portion, which retained the name Bell Labs, ended up with Lucent.
Now with Alcatel's proposed purchase of Lucent in the news, the question as to what will become of Bell Labs has arisen. As this article points out, this is not simply a matter of industrial reorganization, as Bell Labs historically had close ties to government projects that have homeland security implications.
Should this be sufficient grounds for the US government to block the merger? Should the US Government take over these labs? Should the US Government keep out of the deal and see to their homeland security needs via other mechanisms? Is there enough of the "original" Bell Labs left for this to be a significant issue?
