Although the Best Buy electronics chain has not actually stopped selling CDs in their stores as of July 1st (something widely reported of late), CD's are certainly fading away quickly.
A visit to you local Best Buy will likely reveal a dusty corner in which lurks a small collection of "select CD titles", huddling together for warmth and companionship.
Switching to Old Fart Mode™, I can recall the advent of the CD and the promise of unsullied digital sound reproduction that would last forever. The glorious silence as I cranked up my first CD (Queen, of course), then the booming digital cascade that followed...
While I may be exaggerating the "forever" part, they were definitely seen as a huge "next step" towards some kind of musical Nirvana - now, they are perversely fighting for shelf space with vinyl albums, which have curiously made a comeback among (I guess) the hipster types.
True, we still largely listen to digital music (of which CDs were the mainstream vanguard), but now we stream or download in a variety of formats, and the idea of having a CD collection has apparently become quaint - like bicycles with shopping baskets.
