Best Buy, one of the last big-box electronics chain stores still in business, will be phasing out all CD sales by July 1, Target is expected to make a similar move, selling CDs only on consignment, which will essentially leave the aging digital disc to be relegated to a few last bastions, including Walmart, a motley collection of record shops with a CD section at the back, and of course, online distributors like the all-powerful Amazon.

Many of us have rich memories of our time with the Compact Disc, from the first cartridge we cracked open outside a Sam Goody, to the overstuffed wallets and CD towers in our living rooms that stored hours upon hours of digital music bliss. As such, we decided to see the CD off in style with this trip down memory lane. Follow us below as we chronicle the rise and demise of the late, great, Compact Disc.

The sample rate is based on the Nyquist theorem shout out to our fellow nerds , which, in this case, outlines the minimum rate needed to replicate all frequencies humans can theoretically hear. The resolution is still regarded by many as the optimal digital standard.

Born, as Sony states , nearly years after the first phonograph player, the CDP made its way to the U. Following an initial offering of around 20 available albums at launch, the CD exploded over the next few years.

The design was, in part, an effort to make it easier to flip through discs on shelving units designed for LPs, but it was also aimed at theft prevention. In addition to not needing to rewind, DVDs also came with cool extras like deleted scenes, interviews with actors and actresses, and even music videos. I remember when DVDs first started making it big, because Blockbuster would get about 2 DVD copies of the newest movies, and they were always sold out.

But where exactly did DVDs come from? It turns out that the history of DVDs is a bit more interesting--and older--than you might realize. Two guys named David Paul Gregg three first names, really?! David figured out the video encoding part, and James figured out the recording part. With their powers combined, they made the first laser storage discs. A strange format called LaserDisc was released in Atlanta, Georgia.

It used large discs--about 2. While this format never really took off, it was an important stepping stone to the invention of the DVDs that we know and love today. It took floppy discs.
