Abstract :
Interesting early experiments and significant technical milestones are described in radiotelephony preceding the birth of the broadcasting industry at KDKA in 1920. The technical problems and difficulties which faced the burgeoning early growth and subsequent development are outlined and the most significant advances in the technology are outlined as they occurred in both AM and FM broadcasting. The descriptions are accompanied by comments concerning the past, present and possible future status and trends in both services and the manner in which they may be influenced by factors which are unique to each.
