Originally made by Fry's since 1929, Cadbury's took over production of Crunchie bars in the early 1970s. The main colour at this time was orange but was switched to gold in the mid-1980s.
After more than 20 years, the Crunchie received a major overhaul for the first time. The heart in the "i" was changed to a yellow star, and the font was completely altered and stylized.
Like all Cadbury products, the Crunchie underwent a slight alteration in 2003. The yellow star was now a red explosion, and the text was mildly altered. In 2015, the Cadbury swirl was replaced with just the typeface in gold.
