Rowntree
& Co. Ltd started to sell their Black Magic chocolates for the first time
in 1933. Who now can forget the famous voice-over by
Steve Hudson: "Who knows the secret of the Black Magic Box?"
In 1969 Rowntree
& Co. Ltd and John Mackintosh & Sons Ltd became Rowntree Mackintosh Ltd.
The company changed its name to Rowntree PLC in 1987. In 1988 Nestle SA bought
Rowntree PLC.
