Black Friday is generally the day people go crazy and buy a lot of things at shops. The most was the Nintendo Switch console this year.
Adobe Digital (through Nintendo Today) posted up a list of the highest selling items that people bought on Black Friday. The Switch beat the rest out by racking data from 4500 websites selling a huge number of items.
The top selling items are:
1) Nintendo Switch
2) Hatchimals & Colleggibles
3) PJ Masks
It has been a great year for Nintendo thanks to the release of the Switch. 2018 is expected to be an even bigger year as more stock is being made to avoid stock shortages.
