A while back I linked to an article explaining just how mind-blowingly massive a petabyte of digital storage is (see How Much is a Petabyte?). Today, the same website put up a similar post that visualizes physical vs digital storage. It's pretty awesome to see how we have progressed over the years. With the invention of CDs, DVDs, and MP3 players, the world has found much more space to store data. Why is this so important to us humans? It's probably just something hard-coded into our DNA. We like to store and retain everything we can.
From the site...
"Recording information is an inherent part of our humanity. As we evolve, we create more efficient means of storing this information. Since the creation of computers, we have greatly increased our ability to store and access large quantities of information."

People may see the stats at the site above and think, "Wow, that's a lot of data. How can companies afford to host all of that, isn't it expensive?" While this is a natural response, people still have to realize that all of this storage that companies offer for free (which costs them millions) is offset by other, paid, services that they also offer. The Apple App Store, for example, brings in nearly $200 million a month (see How Big Is the Apple iPhone App Economy?). That's insane! Google, while offering many free things, also makes an insane amount of money on advertising, and even their version of the App Store, the Android Market (currently $5 million a month and growing).
I'm not sure what my point is. I don't know where I was going with this post, but I think it's clear that advancements in digital storage are tremendous. Now that the world has already experienced all this storage and technology, can anyone imagine what life would be like if all of the sudden we didn't have any of it? Imagine their being no Google, iPods, and dare I say, Facebook. How different would the world be?
Pretty scary thought...
