Око 1920, технологија је сазрела у довољној мери да је радио емитовање брзо постајало одрживо.<ref>{{cite web|url=http://www.makingthemodernworld.org.uk/stories/the_age_of_the_mass/07.ST.04/?scene=4 |title=The Invention of Radio}}</ref><ref>{{Cite journal|last=Guarnieri|first=M.|year=2012|title=The age of vacuum tubes: the conquest of analog communications |journal=IEEE Ind.

[[Charles Herrold|Чарлс Херолд]] је започео емитовање у [[Калифорнија|Калифорнији]] 1909. године и преносио је аудио сигнале следеће године. (Херолдова станица је коначно постала [[KCBS (AM)|-{KCBS}-]]).
