It’s hard to find someone who’s never tried Duolingo. Even their sound effects are recognizable (along with their chubby green mascot of course). Good job keeping the brand intact for so long.

Mimo’s animation is cute as a button. Given that these ads launched quite a long time ago, we can only assume that they’ve been melting hearts and attracting absolutely everyone to try coding lessons - from little girls to their grandfathers.

Strictly speaking, there’s nothing super special about these ads by Word of the Day, but if we now know what nomophobia is, you should too. The obvious lesson here is that simple educational content is highly shareable.
