For the department of “forgotten products”: Rowntree’s Tokens. They were launched amidst a big fanfare in 1963 and disappeared off shelves in 1964 – a lifetime of under a year. Clearly the idea of a wealth of centres – 14! – but advertising them as all being just chocolatey with little differentiation wasn’t enough to drag people away from Cadbury’s Roses or Rowntree’s own Dairy Box.
