It is commonly used in MP3 players, computer BIOS code and thumb drives. Originally developed in Japan by Toshiba, it has become quite popular for products requiring non-volatile erasable memory. Flash devices have a limited number of erase cycles (typically 10,000 to 1,000,000 cycles), so they're not as good a choice for applications in which the data changes constantly. However, since it has no moving parts (unlike a hard disk), it is an excellent choice for storing the operating code for small personal electronics like PDAs, cellphones, digital cameras and the data in items like MP3 players.

JVC (Japan Victor Corporation) and Matsushita (Panasonic) developed the VHS format to compete with Sony which developed the Beta format as the first home video cassette recorder. VHS originally stood for Vertical Helical Scan, but now means Video Home System.
