Hello Americans was produced concurrently with Welles's other CBS series, Ceiling Unlimited, a salute to the aviation industry, and his work was considered a significant contribution to the war effort.

Orson Welles produced Hello Americans under the auspices of the Office of the Coordinator of Inter-American Affairs, created by PresidentFranklin D. Roosevelt in July 1941 "to provide for the development of commercial and cultural relations between the American Republics and thereby increasing the solidarity of this hemisphere and furthering the spirit of cooperation between the Americas in the interest of hemisphere defense."

"The best good-will propaganda is to sell South America to North America," Welles wrote coordinator Nelson Rockefeller. Welles could draw upon the research amassed earlier in 1942 for It's All True, the film project he had embarked upon also at the request of Rockefeller, who was a major RKO Pictures stockholder and Welles admirer as well as Coordinator of Inter-American Affairs. It was hoped that the dramatizations would counteract German and Italian propaganda and build solidarity among American republics in the hemisphere.

"The pan-American cause, with its inclusiveness, its celebration of diversity and its challenge to the values of white Anglo-Saxon Protestantism, was something to which Welles felt deeply attracted," explained biographer Simon Callow. "Welles constantly sought the most vivacious method of presentation … interviewing the great dead as if they were alive, evoking the country in question in sounds and atmospheres, dramatising the historical while never forgetting the present reality: conquistadores rub shoulders with civil engineers.

"They were good shows, I thought," Welles told filmmaker Peter Bogdanovich:

All inter-American affairs. I did the A-B-Cs of the Caribbean. And they were very amusing. I didn't really do much of it — the writers were awfully good. And it was a good form. A-B-C: "A" is for "Antilles," "Antigua," and so on. We went through like that and did little things and big things, with music and stories each week. I'm queer for the Caribbean anyway — not as it exists, but as it was in my mind in the 18th and 19th centuries. The Caribbean is just great stuff. All of it. The whole idea of all these empires fighting over tiny little islands, and black independence and Spanish pride and the War of Jenkins' Ear and those great earthquakes.

The series finished at the end of January 1943, when its sponsor concluded that the program failed to attract a sufficient audience.
