on the rise of 3D games.  The most compelling development is the stereoscopic 3D glasses that will be used in the upcoming Avatar game, based on James Cameron’s next film. 



While 3-D films have been around for decades, innovations in digital projection technology are ushering in a new age of eye-popping action.  A Santa Monica, California start-up called Real D is leading the crush to cash in.   As Michael Lewis, co-founder and CEO of Real D told me, “Cinema is the tip of the sphere to get the consumer indoctrinated in new generation of 3-D.”



Real D’s business model is built around the licensing of its software and hardware.  Light is circularly polarized from the digital projectors onto a special silver screen, which helps capture the images.  Instead of donning clunky headsets or red and green lenses, viewers wear lightweight stereoscopic glasses that can be recycled or trashed after use.  Competitors, such as Dolby, have introduced 3-D systems requiring costly washable glasses.  Unlike Real, Dolby’s projection technology can be utilized using a theater’s existing white screens.  I doubt it will be long before 3D glasses occupy another shelf in the living room, right next the Rock Band drumsticks.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
