Cadbury's Curly Wurly
The Curly Wurly bar was launched in 1970 and was notably advertised on British TV by comedian and actor Terry Scott.
Curly Wurly underwent its first major revamp in around 1988 when the original font was replaced with a more updated logo. This logo introduced the multicolour scheme that is still used today.
In the mid-'90s the bar had another revamp, this time introducing the Cadbury's box, which was commonplace at the time, a new font, and also slightly altering the colour-scheme to its present colours. The white and yellow letters were removed, although yellow was still used for the outline of the font.
In 1998, the Curly Wurly bar underwent a slight overhaul to tie into the Cadbury Land series of adverts that were broadcast at the time. This overhaul notably had a chocolate mascot named CurlyWurly on the packaging.
Cadbury Curly Wurly
The Cadbury products overhaul in 2003 saw the introduction of a much-altered logo, now in 3D, although the same colour scheme was kept. The Cadbury swirl was also added.
As part of a revamp in 2009, Cadbury gave the Curly Wurly a more retro themed logo. Returning to 2D and adding curly lines around the wordmark. The Cadbury swirl was removed in a minor alteration in 2015.
