에이티앤티(AT&T) - Rethink Possible

In 1998, AT&T announced a US$1 billion alliance with BT to offer global voice over IP (VoIP) services, called Concert, sparking rumors of a potential merger. But the parties fought for control of the project and could not even agree on the alliance's name. By mid-2001, customers were being directed to sign contracts with the parent companies, and Concert Communications Services, as the venture was eventually known, was scrapped in October that year.


In 1999, AT&T acquired the Olivetti & Oracle Research Lab, from Olivetti and Oracle Corporation. In 2002, it closed down the research part of the lab.
