Inventor Victor T. Hoeflich, founder of novelty manufacturing corporation American Merri-Lei of Brooklyn, New York, introduced his “Man-from-Mars Radio Hat” in March 1949.
In the press conference, he used teenagers as models. Sold in department stores across the U.S. and by mail, the hat retailed for $7.95. Designed after a pith helmet, it could be ordered in eight colors: Lipstick Red, Canary Yellow, Blush Pink, Rose Pink, Tangerine, Flamingo, Chartreuse and Tan. Later seven more color options were added.

While the transistor had been invented in 1947, it was still experimental and not widely available. And portable transistor radios did not appear until 1954.
