I always thought it was odd that two such similar drinks were marketed in such contrary ways. Horlicks to make your sleep and Ovaltine to give you energy. Perhaps that was the point at which I realised marketeers weren't always scientific in their advice :(

Growing up in the US in the 1990s it was marketed as chocolate milk with vitamins (so therefore good for your kids).

They should call it Round-tine!
However it brings up a funny story: the original name is Ovomaltine, not Ovaltine, referring to the egg (ovum) and malt ingredients (I think there's no eggs inside anymore). But there was a typo in the trademark application for UK early on, and the name stood like that. It's still Ovomaltine in Italy, for example.
Now, on Wikipedia there is no source for this story, and it might be possible that they decided to change the name for easier pronunciation in English, or because the connection ovum->egg was difficult anyway, or other unknown reasons, but I want to believe the first version anyway.
