Founded in 1961 in Silicon Valley, Memorex began as a supplier of computer tapes and later became known for its famous “Is it live, or is it Memorex?” ad campaign featuring Ella Fitzgerald. The brand expanded into media like disk packs and peripherals for IBM mainframes, becoming a major independent supplier of drives and controllers. Today, under Imation, Memorex focuses on consumer electronics including blank CDs/DVDs, flash storage, and accessories, with media manufactured by CMC Magnetics, Ritek, and Moser Baer.
