Scientific Atlanta was a premier manufacturer of cable television equipment and broadband modems. Acquired by Cisco and later Technicolor, its legacy set-top boxes remain in widespread use.
Scientific Atlanta was a renowned American manufacturer of telecommunications equipment, best known for its pioneering work in the cable television industry. Founded in 1951, the company produced millions of digital set-top boxes, cable modems, and transmission network systems that powered home entertainment for decades. Notable product lines include the ubiquitous Explorer series of digital video recorders and cable boxes.
In 2005, Scientific Atlanta was acquired by Cisco Systems, integrating into their Service Provider Video Technology Group. Later, in 2015, the Connected Devices division—responsible for set-top boxes and modems—was sold to Technicolor (now known as Vantiva). While the Scientific Atlanta brand name has largely been retired from new consumer products, legacy devices are still widely supported by cable providers and used in households globally.
