DVD was originally for Digital Video Disc. But others opposed this and suggested that the DVD should be – Digital Versatile Disc. The reason for thisThe argument was that the name given the widespread use film, even for non-video applications. Toshiba, one of the largest producers of electronic goods to date, and continue the interpretation of the Digital Versatile Disk. The course is still not completed ..
