Harman International Industries, Inc., headquartered in Stamford, Connecticut, designs and manufactures audio, video, and lighting products for automotive, professional, and consumer markets. Founded in 1980 by Dr. Sidney Harman to acquire the JBL loudspeaker unit, the company traces its roots to Harman Kardon, established in 1953 by Sidney Harman and Bernard Kardon. Harman operates multiple business divisions serving automakers with connected car systems (including products like Ready Upgrade, Ready Care, and Ready Display), professional venues and studios, and consumer electronics through brands including JBL, Infinity, Harman Kardon, AKG, Crown, Lexicon, Mark Levinson, Revel, and others.
