24/7 Wall St.

A massive trade exhibition like the Consumer Electronics Show which officially opened today in Las Vegas carries with it a low of ‘wow’ — and this year’s show is no exception. There’s not much impact on share prices though, because most of the products that companies are showing off won’t be on the shelves for some time yet or they’ve just hit the shelves and companies are trying to get some traction in the market.

Here’s a rundown of some of the tech heavyweights and what they’ve put on display.

Apple Inc. (NASDAQ: AAPL) does not have a booth at CES but it’s hard to escape the feeling that every smartphone, tablet, and Internet TV is in some way being compared to the iPhone, iPad, or Apple TV. Apple’s shares are up fractionally at $524.06 in a 52-week range of $418.66 to $705.07.

Intel Corp. (NASDAQ: INTC) is pushing its low-power consumption Atom processor in a variety of applications, some of which won’t be available until around Christmas 2013. Intel’s shares are up 0.2% today at $21.30 in a 52-week range of $19.23 to $29.27.

Advanced Micro Devices Inc. (NYSE: AMD) is also pumping its low-power consumption processors aimed at the tablet market, where the company has virtually no presence Shares are up 0.4% at $2.68 in a 52-week range of $1.81 to $8.35.

Sony Corp. (NYSE: SNE) is pushing numbers — specifically, lots of pixels in its Ultra HD 4K-pixel monitors — which, while impressive, show just how badly the once-dominant maker of consumer electronics gear has missed the bus. Sony’s shares are down 2.8% at $10.66 in a 52-week range of $9.57 to $22.35.

Nvidia Corp. (NASDAQ: NVDA) introduced a new Tegra-4 processor and hand-held gaming platform called Project Shield that runs Android games like those found on smartphones and tablets using Google’s operating system. Shares are down 1.5% at $12.58 in a 52-week range of $11.15 to $16.90.

Google Inc. (NASDAQ: GOOG), like Apple is not at the show, but has announced new partners for its Google TV platform and other partners, like LG Electronics, Vizio, and Sony, are showing off new hardware as well. Google’s shares are down about 1.1% at $726.85 in a 52-week range of $556.52 to $774.38.

Qualcomm Corp. (NASDAQ: QCOM) said it is sending out samples of a camera chip that can record 4K Ultra HD video from a cellphone. Shares down about 0.3% at $63.84 in a 52-week range of $53.09 to $68.87.

Samsung Electronics is getting props for beating Apple to the punch with a voice-controlled TV again with 4K Ultra HD resolution.

Added to the list of heavyweights not present are Microsoft Corp. (NASDAQ: MSFT) and Amazon.com Inc. (NASDAQ: AMZN).

The consumer electronics industry is making another push into TV this year, and not just with the 4K Ultra HD devices with screens up to 85 inches in size. Internet-connected TVs are the next big thing, the device that will fit in with the smartphones and tablets consumers are already using to stream content and play games on the relatively tiny phone and tablet screens they already own. Pushing — or, in industry parlance, throwing — content to the big screen from your little hand-held device is the next holy grail.
