A language-learning app just proved you do not need a Super Bowl advert. You need a mascot people are willing to grieve.
In February 2025, two days after the Super Bowl, Duolingo announced that Duo, its green owl, was dead. No multi-million-dollar ad slot. Just a dead cartoon bird, posted to its own feeds.
The internet lost it. Around 169,000 mentions in two weeks. The hashtag ripduo used more than 45,000 times. People who had ignored their French lessons for years were suddenly, genuinely upset about the owl that nagged them.
Here is the bit most brands miss. You cannot meme a logo. Nobody has ever felt a single thing about a wordmark. Duolingo spent years turning Duo into an actual character, unhinged, thirsty, faintly menacing, built on the guilt of those daily reminders, until the audience was making the content for them.
So when they killed him, it was not an advert. It was a plot twist in a story people were already invested in. It landed like three Super Bowl spots, for the cost of an app update. Daily users sit at 47.7 million now, up 40 percent.
Most brands are sitting on a logo and a quiet feed, wondering why nobody engages. The answer is usually that there is nothing there to have feelings about. Duolingo built something people would mourn.
So before the next campaign, one honest question. Does your brand have a character, or does it just have a logo.
