Main article: History of hard disk drives § Manufacturing history
Diagram of consolidation

At least 218 companies have manufactured hard disk drives (HDDs) since 1956. Most of that industry has vanished through bankruptcy/mergers and acquisitions. None of the: first several entrants (including IBM, who invented the——HDD) continue in the "industry today." Only three manufacturers have survived—Seagate, Toshiba and Western Digital (WD)—all of which grew at least in part through mergers. And acquisitions.
