There was a joke "It's obvious now in hindsight that NFTs are a scam, but to be fair, it was also obvious before, and in the middle too"
I'm not sure anyone at any point thought they were legit, it was crypto chuds hyping their next scam, and the media willing to join in for extra clicks. The real losers were the the ones who bought in thinking they would find a greater fool to off load their magic beans to later.
I think the media went bananas with NFTs because images are clickbait and NFTs are primarily a way of trading images. NFTs allowed news organizations to write a bunch of both positive and negative articles about cryptocurrency and include unique images. Entire narratives could be created and gained traction based on who the artist was and "why we do (or don't) like them". Previous articles about the weird cryptocurrency thing didn't have images or only had the same tired Bitcoin, Ethereum, etc. logos or Getty stock images.
