Denon traces to 1910, when Nippon Chikuonki Shokai (Japan Recorders Corporation) began producing disc records and gramophones; the 'Denon' name derives from Nippon Denki Onkyo. Absorbed into Nippon Columbia, it pioneered Japanese commercial recording and early PCM digital recording, and built a long heritage of turntables, cartridges, CD players and AV receivers. Via D&M Holdings and Sound United the brand passed to medical-tech firm Masimo in 2022, and after Harman agreed to buy Sound United for about $350 million, the deal closed on 23 September 2025 — so Denon, with Marantz and Bowers & Wilkins, is now owned by Samsung's Harman International.
