A look back at London Underground's Cadbury's vending machines

The vending market can be an ever changing beast - with new technologies, changing habits and different products changing in popularity, things can change quickly.

MyLondon recently looked back at one particular type of vending machine that used to be very popular on the London Underground, but were phased out without any official announcement - Cadbury's vending machines.

The change has been enough to prompt various theories and discussion online, which shows how much vending machines can have an impact. Interestingly, the article concludes by revealing that whilst Dairy Milk is easily the UK's best selling Cadburys bar, on the London Underground it proved to be the Whole Nut variety that took the crown.
