Excuse me, but when you buy a CD, DVD, etc. it IS digital data. I’m so sick of this talk about digital music to mean downloads when CDs are digital too. Even worse is the DVDs that claim “Digital copy included” referring to an avi or the like. Of course it includes a digital copy. It’s a bloody DIGITAL Video Disc (subset of Digital Versatile Disc).
Another one is “BluRay DVD” - they’re two separate (and now competing) formats. That’s like saying Betamax VHS.
Another one that finally passed but was prevalent back when CD was new was “CD records” or “CD tapes”.
Oh well, I think I’ll go hop in my Ford Chevy and get out of here.
