The radio hat was a portable radio built into a pith helmet that would bring in stations within a 20-mile (32 km) radius. It was introduced in early 1949 for $7.95 as the "Man-from-Mars Radio Hat."[1] Thanks to a successful publicity campaign, the radio hat was sold at stores from coast to coast in the United States.
The radio hat was manufactured by American Merri-Lei Corporation of Brooklyn N.Y. The company was a leading supplier of party hats, noise makers and other novelty items. Its founder, Victor Hoeflich, had invented a machine to make paper Hawaiian leis while still in high-school (1914), and by 1949 the company shipped millions of leis to Hawaii each year. An inventor and gadgeteer,[2][3][4] Hoeflich continued to develop and even sell machinery that manufactured paper novelty items.[5][6]
Battery-operated portable radios had been available for many years, but Hoeflich hoped a radio with innovative packaging and a publicity campaign could be a runaway success. The transistor had just been invented, but was still an expensive laboratory curiosity; the first pocket transistor radio was still 5 years away. This radio would have to use the existing vacuum tube technology and the tubes would be a prominent design feature. The loop antenna and the tuning knob were also visible. The hat was available in eight colors: Lipstick Red, Tangerine, Flamingo, Canary Yellow, Chartreuse, Blush Pink, Rose Pink and Tan.[7][8]
