Are you KIDDING?
Seems you weren't really paying attention to the industry during the dotcom bubble. EVERYTHING was gonna be sold online, and MP3 had been around for quite a while at that time. You realize that Napster was already in full swing? The whole idea that you could sell digital content ONLINE. omg, why did no one ever have that idea before those guys patented it? /sarcasm
napster was p2p sharing
the company that filed this patent sold encrypted/DRM's music online in 1998. and the way he sold it and DRM'd it is pretty much the way iTunes started doing it a few years later. it was a cool idea but ahead of it's time. why buy music online that can only be played via the special player software when you can just buy a CD and rip it?
i think that was the year the first 1MB MP3 players came out. i had a dual celeron PC i built while in the army and was borrowing everyone's CD collections and ripping them
