CenturyLink

CenturyLink, Inc., later rebranded as Lumen Technologies, was a major American telecommunications company that provided voice, data, and broadband services to consumers and businesses. It originated as Century Telephone Enterprises, founded in 1968 to operate small local telephone exchanges in the United States. Through a series of acquisitions, most notably the 2009 purchase of Embarq and the 2011/2017 acquisition of Level 3 Communications, CenturyLink expanded into long-haul fiber networks and IP-based services, enlarging its enterprise and wholesale capabilities. In 2010 the company adopted the CenturyLink name for its consumer and business services; in 2017 it completed the Level 3 acquisition, creating one of the largest telecom networks in North America.

In 2020 CenturyLink rebranded corporate operations as Lumen Technologies, while the CenturyLink brand continued to be used for consumer internet, phone, and related services in the United States. The combined company offers a range of services, including residential broadband and voice, Ethernet, IP/MPLS, cloud and managed services, data center connectivity, and security solutions, serving telecommunications carriers, enterprises, and government customers. The CenturyLink/Lumen entity operates a global network with extensive fiber infrastructure, delivering services across North America and select international markets.
