where does the term disc jockey come from
Disc jockey The term "disc jockey" was ostensibly coined by radio gossip commentator Walter Winchell in 1935, and the phrase first appeared in print in a 1941 Variety magazine, used to describe radio personalities who introduced phonograph records on the air.[28][29] Playing recorded music for dancing and parties rose with the mass marketing of home phonographs in the late 19th century, and Jimmy Savile is credited with hosting the first live DJ dance party in 1943. Savile is also credited as the first to present music in continuous play by using multiple turntables. In 1947, the Whiskey A Go-Go opened in Paris as the first discoteque.[30] In the 1960s, Rudy Bozak began making the first DJ mixers, mixing consoles specialized for DJing.
History of the floppy disk IBM Direct Access Storage Product Manager, Alan Shugart, assigned the job to David L. Noble,[8] who tried to develop a new-style tape for the purpose, but without success. The project was reassigned to Donald L. Wartner, 23FD Disk Drive manager, and Herbert E. Thompson, 23FD Disk manager, along with design engineers Warren L. Dalziel, Jay Brent Nilson, and Ralph Flores; and that team developed the IBM 23FD Floppy Disk Drive System (code name Minnow). The disk is a read-only, 8-inch-diameter (200Â mm) flexible diskette called the "memory disk" and holding 80 kilobytes of data. Initially the disk was bare, but dirt became a serious problem so they enclosed it in a plastic envelope lined with fabric that would remove dust particles.[9] The Floppy Disk Patent #3,668,658[10] was issued on June 6, 1972 with named inventors Ralph Flores and Herbert E. Thompson. The Floppy Disk Drive Patent #3,678,481[11] was issued July 18, 1972 with named inventors Warren L. Dalziel, Jay. B. Nilson, and Donald L. Wartner. IBM introduced the diskette commercially in 1971.[12][nb 3]
