There are still some technical hurdles to clear before you're watching zany sitcom antics flying toward you, but the trend is clear. The satellite begins full operation in March, and existing DirecTV set-top boxes will simply need a firmware upgrade to support the 3D programming. Unfortunately, you'll still need to pick up a 3D-capable HDTV to play it back, and that's where the market lag will play a role in determining how fast 3D will penetrate.
Although 3D content has a long history stretching all the way back to 1922 -- when the first public 3D movie was displayed -- a number of optics and display challenges, as well as market realities, relegated 3D to a periodic novelty for decades. With the vast majority of the technical hurdles now solved and 3D displays making steady inroads at seminal trade shows like CES over the past couple of years, 2010 is poised to be 3D's breakout year. The emergence of a string of blockbusters like Avatar, Alice in Wonderland and more rounds out 3D's emergence -- or re-emergence -- on the big screen. Soon, consumers will come to expect the same experience in their home theater as well.
