OnJanuary1,1925,whenAT&Tpresident,WalterGifford(WalterGifford)acquiredtheresearchdepartmentofWesternElectronicsCorporation,acompanycalledAnindependententityof"BellTelephoneLaboratories,"laterrenamedBellLaboratories.AT&TandWesternElectronicseachown50%ofthecompany.Inthe1920sand1930s,BellLabsresearchersintroducedlong-distancetelevisiontransmissionanddigitalcomputers,leadingthedevelopmentofsoundfilmsandartificialthroats.Twoimportantinventionsoftheinformationage-transistorandinformationtheorywereallresearchedbyBellLabsinthe1940s.ThemajorinventionsofBellLabsinthe1950sand1960sincludedsolarcells,thetheoryoflasers,andcommunicationsatellites.
After1984,inaccordancewiththeUSgovernment'sagreementtospinoffAT&T,BellcorewasestablishedfromBellLabs.BellcoreprovidesunifiedresearchanddevelopmentservicesforaseriesofsmallBellcompaniesafterthespin-off.

High-tech-yrityksenä Lucent on täysin tietoinen tarpeesta investoida sekä perustutkimukseen että tuotekehitykseen.Lucent on aina käyttänyt 11–12 % vuotuisesta myynnistään BellLabsR&D-rahoituksena,noin 40 %. vauhtia.
