What was the most popular american band in 1928?

This is a difficult question to answer because the late 1920s were very good years for so many musicians, and no one group or artist dominated. Radio had become a major force in making songs popular, and as a result, a number of bands and vocalists were heard on the air nationally. There were two new networks-- NBC (National Broadcasting Company) and CBS (Columbia Broadcasting System), and the biggest stars were being heard from coast to coast. There were as many popular vocalists as there were popular bands, in fact. But among the most popular bands in 1928 were Paul Whiteman and his Orchestra, Duke Ellington and his Cotton Club Orchestra, Fred Waring & the Pennsylvanians, and the Coon-Sanders Nighthawk Orchestra.
