Google had to modify its Super Bowl LIX advertisement after an AI-generated mistake was identified in the spot.

In the initial version of the advertisement, which highlighted Wisconsin cheese and showcased Google’s Gemini chatbot, it incorrectly asserted that gouda represents as much as 60 percent of global cheese consumption. This error was initially brought to light by [X user Nate Hake](https://x.com/natejhake/status/1886931460541534488). Although Google’s president of cloud applications, [Jerry Dischler](https://x.com/jdischler/status/1885806962605957555), maintained that the assertion was not an instance of AI hallucination, the company discreetly updated the advertisement to eliminate the erroneous claim.

A professor from Cornell later verified to [The Verge](https://www.theverge.com/news/604679/google-ai-super-bowl-ad-gouda-cheese) that it is improbable for gouda to be the most consumed cheese globally. The inaccurate figure seems to have stemmed from [Cheese.com](http://Cheese.com), and as noted by The Verge, a [Reddit discussion from ten years ago](https://www.reddit.com/r/todayilearned/comments/2h2euc/til_gouda_accounts_for_over_half_of_the_worlds/) had already disproved the assertion.

As AI-generated content becomes increasingly common in advertising, this event underscores the necessity of fact-checking prior to airing prominent commercials.
