Memorex CDX IV - 1989 - US
Memorex had these cassettes manufactured in South Korea. Brilliant looking tapes and high quality type IV as expected.
Established in 1961 in Silicon Valley, Memorex started by selling computer tapes, then added other media such as disk packs. The company then expanded into disk drives and other peripheral equipment for IBM mainframes. During the 1970s and into the early 1980s Memorex was worldwide one of the largest independent suppliers of disk drives and communications controllers to users of IBM-compatible mainframes, as well as media for computer uses and consumers.
Memorex entered the consumer media business in 1971 and started the ad campaign, first with its "shattering glass" advertisements and then with a series of famous television commercials featuring Ella Fitzgerald. In the commercials she would sing a note that shattered a glass while being recorded to a Memorex audio cassette. The tape was played back and the recording also broke the glass, asking "Is it live, or is it Memorex?" This would become the company slogan which was used in a series of advertisements released through 1970s and 1980s.
Over time the Memorex consumer brand has been owned by Tandy, Handy Holdings, Imation and as of 2016 Digital Products International (DPI). Today, Memorex is a brand for consumer electronics and accessories such as portable audio players, iPod accessories, flat panel TVs, Blu-ray Disc players, flash drives, CDs and DVDs.
