TEAC was founded in 1956 as the Tokyo Electro Acoustic Company.

TASCAM - consumer to professional audio products, mostly recording.
ESOTERIC - High-end consumer audio products.
TEAC Consumer Electronics - Mass market audio products.
Data Storage and Disk Publishing Products - Floppy drives, DVD and CD recorders and drives, MP3 players & NAS storage.
TEAC is known for its audio equipment, and was a primary manufacturer of high-end audio equipment in the 1970s and 1980s. During that time, TEAC produced notable reel-to-reels, cassette decks, CD players, turntables and amplifiers.
Of particular note is that TEAC produced an audio cassette with tape hubs reels that resembled reel-to-reel tape reels in appearance. Many manufactures of the time used these TEAC cassettes in advertisements of their tape decks because the TEAC cassettes looked more professional than standard audio cassettes, and because reel-to-reel tape recordings were known to be of higher quality than cassette recordings.
