Final answer:
The popular malted drink among children in the 1930s and '40s was Ovaltine, due to its strong marketing campaigns including sponsorships of radio shows like "Little Orphan Annie" and "Captain Midnight". The correct answer is option 1) Ovaltine
Step-by-step explanation:
The malted drink that was popular among children in the 1930s and '40s, especially due to its sponsorship of radio programs like "Little Orphan Annie" and "Captain Midnight", was Ovaltine. Ovaltine, a brand of milk flavoring product made with malt extract (except in the Blue packaging in the US), sugar, and whey, has its origins in Switzerland and became famous worldwide.
Ovaltine was keen on marketing to children and families, understanding the power of the new medium of radio. By sponsoring wholesome, adventurous shows that captivated the imaginations of young listeners, Ovaltine effectively associated itself with the excitement and heroism that these narratives inspired. This marketing strategy helped to solidify the brand's presence in the American household and ensured its success for decades to come.
Other options like Nesquik, Horlicks, and Milo, though also malted drinks, did not have the same level of involvement or association with these iconic radio programs during that era. The association of Ovaltine with radio show giveaways and secret decoder rings further entrenched its popularity with children of that time, making it a cultural phenomenon.
