The Biggest Electronics Show In The World Is A Pretty Bad Indicator Of The Year Ahead In Tech

The annual Consumer Electronics Show in Las Vegas is the event that's supposed to set the tone in technology for the oncoming year.

Things have changed in recent years though. Technology has become less about whiz-bang gadgets and more about the Internet-powered apps and services we use. Twitter. Instagram. Snapchat. Dropbox. And so on. You don't really need 2 million square feet in the Las Vegas Convention Center to show off a bunch of apps.

Last year, Microsoft famously pulled out of CES, and it was the first time in recent memory that its CEO (either Bill Gates or Steve Ballmer) didn't deliver the opening keynote. Instead, we got a very bizarre presentation from then-Qualcomm CEO Paul Jacobs that included a cameo by Big Bird and a lip syncing Adam Levine.

Also missing last year? We didn't get a single blockbuster product announcement from one of the major tech companies. Instead, companies like Samsung, HTC, and Nokia waited to hold their own events to announce new flagship products later in the year.

So what did happen at CES last year if there weren't any big breakthrough products? There was still a lot going on. But one of the problems with CES in recent years is it hasn't been a good indicator of what the next year in tech would look like. In fact, most of the big themes of CES 2013 were either barely mentioned again following the show or turned out to be major duds.

Let's take a look back at some of the biggest themes of CES 2013 and see where we are now.

4K TVs

4K TVs, also known as Ultra HD TVs, were the biggest storyline of CES 2013. These sets represent the next evolution in picture quality because they have nearly double the amount of pixels across the screen as normal HD sets today. The downside? They're very expensive. 4K TVs can cost tens of thousands of dollars. Samsung just announced a 110-inch set that'll go for about $150,000. Plus, you can't take advantage of a 4K TV set unless the video was shot at that resolution. Today, most content is still shot in normal HD.

Even though 4K TVs are a few years away from being affordable, every tech company from Samsung to Panasonic made a big push in the space at last year's CES. Sharp even one-upped its competitors with a prototype 8K TV set.

We'll probably see more of the same at this year's CES, but don't expect to have one of these sets in your home for another few years.

Smart TVs

As a piggyback to the whole 4K thing, many of the new sets introduced at CES last year were Internet-connected Smart TVs. That doesn't just mean they came with a bunch of built-in streaming apps like Netflix, Pandora, and HBO GO. They also had new interfaces and recommendation engines to help you find new stuff to watch.
