A Future Technology?

Three D movies and broadcasting always seems to be a future technology.  The industry tried again last year to sell 3D TV sets but once again failed in the attempt.  Although some movies are coming out in 3D, the movie industry has not adopted it on a major scale.  There are reasons why.  People don’t like to wear glasses when watching a movie.  3D is often used gratuitously rather than advancing a plot.  Some movies don’t lend themselves to 3D.  The technology is not new.  It has been around in various forms since the 1950s, but it failed to sell then too.  It seems 3D is a medium of a future that never quite comes.  The same thing happened to the picture phone.  AT&T introduced the concept in the early 1960s, but it didn’t sell then or anytime in the next 30 years.  It wasn’t until the internet was firmly established that people began “face-timing” one another and then they weren’t using a landline phone but their computers and later, mobile phones.  It is a mystery that some technologies fail to impress even when they have proven benefits.
