NFT, or Non-Fungible token, is an expression that has circulated extensively on culture and technology pages over the past year.

NFT can perhaps most easily be described as a form of digital ownership certificate that becomes primarily relevant in the sale of digital art.

But things like tweets, memes and classic YouTube clips have also had their NFT sold.

According to Björn Jeffery, tech analyst at Svenska Dagbladet, the ownership of an NFT can be likened to a logbook that verifies that the work is an original and where you can follow who has owned a specific object at different times.

If you buy an NFT, you get your name in the logbook for each object.

- It's really less about wanting exclusive rights over something, but more about wanting the original (...) that you own the rightful and first version, says Björn Jeffery, tech analyst at Svenska Dagbladet.

Sold and taken down

One of the world's most famous YouTube clips "Charlie bit my finger", is one of many items that have recently been sold as an NFT.

But the new owner did something unexpected and removed the clip completely from the website.

- I have never seen anyone do this before, but if I am to speculate, I think it is about wanting the attention of taking it down and that you will then put the clip back somewhere else, says Björn Jeffery and continues.

- Just removing it to have it on your hard drive and watching it in private use, seems a bit expensive.

Does not affect availability

However, the fact that an object is sold with an NFT should in practice not affect outsiders' access to the object, provided that the new owners do not take down the material.

On the other hand, NFT enables a form of collecting.

- There are quite a few who grew up and spent the majority of their lives on the internet.

And then it is clear that there is value in collecting that type of art phenomenon, or internet phenomenon, says Björn Jeffery.
