Sony announced it will discontinue sales of its 3.5" floppy disks at the end of March 2011. The move marks the death of the floppy disk as Sony is one of the last major manufacturers of this ancient storage medium.
The 3.5-inch floppy was a ubiquitous and necessary component for storing and transferring files between personal computers for nearly three decades. Sony pioneered the 3.5-inch floppy disk in 1981, eventually replacing the 5.25-inch floppy disk that had previously been the popular storage format.
However, as the size of files and programs grew, the floppy disk was pushed aside by inexpensive and larger-format storage medium. Thanks to the creation of storage methods such as CDs, DVDs, Zip, and USB drives, Sony saw its Japanese sales of floppies decline from a record 47 million disks in fiscal 2002 to 12 million in fiscal 2009.
