What does DVD stand for?

The answer is: Digital Versatile Disc. There was a brief war when DVD technology came out in the mid-90s — those who thought it should stand for “digital video disc” and those who argued for “digital versatile disc.”Computer companies were concerned that branding the technology with the term “video” would mean consumers wouldn’t be able to understand all the many other potential applications. The versatility of DVDs were one of their strongest attributes, so the “V” officially stood for “Versatile” as determined by the DVD Forum — but people just say “I’m gonna watch a DVD” anyways, and "digital video disc" is also considered acceptable today.Source
