When Spangles were introduced to the British public in 1950 sweets and sugar were still rationed. Presumably because of the lack of actual sugar content Spangles only needed one ration point instead of the two required for most other sweets and chocolates. Because of this and the expensive and effective advertising Spangles became particularly popular to the confectionary-starved UK market.
It only lasted about a generation, however, and Mars decided it was all over for old-fashioned sweets in 1984. Spangles were re-introduced ten years later but only sold in Woolworths and with just two flavours – orange and blackcurrant. It was only a brief, last flourish and the translucent fruit flavoured sweets were finally discontinued soon after.
