Rating : - Consists entirely of pop-sociology fluff. Devoid of technical or business content.
There are interviews with elderly people recollecting the first time they heard a radio program. There is footage from old radio programs, that is, from the work done by actors in studios. There are images of glowing radio tubes, with no attempt to explain what is going on. There is footage of Frank Sinatra singing about the radio business. There is commentary on Lee de Forest's love life. The disc consists entirely of pop-sociology fluff. This disc is an insult to the viewer.

There is little or nothing on this disc relating to the inventive process, technological or commercial developments, intellectual property issues, or business efforts, in the history of the radio industry.

There is little in the disc to hold the attention of any intelligent child or adult. The disc under review is a real challenge to the mind. What this means is that the task of finding anything interesting in the disc is a real challenge.

The disc claims to have been inspired by Tom Lewis' excellent book, Empire of the Air. I found little resemblance, except in the titles. Tom Lewis' book, Empire of the Air, is a captivating, fact-based, account of the business and commercial interests of the various inventors of the radio, and radio broadcasting. Mr.Lewis' book does not digress into the wasteland of pop-sociology fluff, as does the disc. Tom Lewis' book gets FIVE STARS.

Tom Lewis' book Divided Highways, an accounting of the recent history of the U.S. highway system, also deserves FIVE STARS. If you are further interested in engineering and inventions from the early 20th century, I would also recommend John Van Der Zee's highly readable book about the Golden Gate Bridge: The Gate: The True Story of the Design and Construction of the Golden Gate Bridge. John Van Der Zee also gets FIVE STARS.

But the disc under review is pure junk, an insult to anyone in the radio business or radio industrym, and an insult to any curious child or adult. ZERO STARS for the disc.
