Editor's note: Digital lifestyle expert Mario Armstrong is covering CES from Las Vegas for HLNtv.com and HLN.
This year, CES 2013 has more than 3,000 exhibitors showing off their latest tech in hopes of catching steam and becoming a major player. But not all promising products survive. Here's a quick look at some big buzz technologies launched at previous CES shows that didn't quite catch on.
3D TV (2010, 2011)
Seems like last year 3D TV was all we heard about at CES. You would have thought we'd all be wandering around with blue and red glasses on our faces by now, but for the most part, 3D TV has failed to catch on. It's still a feature in lots of TVs shipping now, but it doesn't seem like anybody's interested in talking about it -- or watching it.
HD DVD (early 2000s)
Format wars! With VHS vs. Betamax still visible in the rear view mirror (objects may be closer than they appear!) as the new millennium began, the major electronics manufacturers and movie studios decided to go for format wars, round 2 with HD DVD vs Blu-Ray Disc. Sure, HD-DVD may have been a better name, but it still lost out to Blu-Ray and was formally discontinued in 2008.
Apple Pippin (1996)
This one is a classic flop! Pippin was Apple's attempt to break into the home gaming console market by offering a machine others could make games for. Bandai took on the challenge, making games and marketing their version of the Pippin, but at $599 and way ahead of its time, it didn't go anywhere. The Sony PlayStation remained the market leader and poor Pippin didn't even make a dent.
Nintendo Advanced Video System (1984-1985)
Don't be fooled: In a way, this one is actually a CES success story. Nintendo introduced the AVS at CES in 1984, but it failed to take off. Rather than giving up, Nintendo took the opportunity to do a reboot, stripping out the "computer" features of the AVS to leave the simpler and easier to understand NES. You know, the Nintendo Entertainment System. It debuted at CES 1985 and the rest is history.
It's hard to believe, but LaserDisc launched at CES way back in 1974 and the very last LaserDisc was released in North America in 2000. Yet somehow in the intervening 26 years, LaserDisc was never really very popular. At the time, it was way more expensive than VHS and Betamax (though it did offer higher visual quality). It later enjoyed its popularity peak in the late 80s/early 90s, but ultimately couldn't compete with DVDs in the years that followed. Gone but not forgotten, LaserDisc is almost the technological godfather of the CD, DVD, and Blu-Ray player.
