Aiwa
Founded in 1951, Aiwa made its mark in cassette decks in 1964 and gradually helped cultivate the large mini-system and personal stereo market of the late 1980s and early 1990s. Aiwa also had a large presence in the markets for headphones and DAT (Digital Audio Tape). Sony acquired the company in the early-2000s, but the brand slid downhill and today no longer exists, despite the website still being "active".
