I am interested in the topic relating to item 1 since that is one area I have always been interested in…PBS did a great documentary back in the 1990’s called “Empire of the Air” which highlights the contributions of Marconi, DeForest, Armstrong and Sarnoff. The DVD is still available on Amazon…So perhaps a section on the contributors to radio would be great to have on this site ( there are many other contributors as well such as the Canadian inventor Fessenden for example …)
