Getty Images Pringles recently unveiled its latest flavor, "CryptoCrisp," as a one-of-a-kind digital collectible known as an NFT--and the bids to get one went up to more than $2,000. Taco Bell's NFT taco GIFs sold out in a mere 30 minutes. The New York Times sold a column about NFTs for a whopping $560,000. NFTs were even the subject of a sketch on Saturday Night Live, which SNL subsequently auctioned off as an NFT. The winning bid garnered roughly $360,000. It's clear that NFTs are big business, at least for the moment. NFTs, which stands for non-fungible (or not interchangeable) tokens, are unique digital assets that exist on the blockchain. The original function of NFTs was to verify digital art, because they can function as certificates of authenticity. Now luxury fashion labels, real estate companies, pro sports leagues, and even legacy art auction houses such as Christie's, Sotheby's, and Phillips are selling NFTs. Tom Brady recently announced that he is launching an NFT company that will feature collaborations with famous athletes, entertainers, and artists.
