S4C was launched on 1 November 1982 in Wales, one day before Channel 4 in the rest of the United Kingdom, and used the "WALES4CYMRU" logo. S4C stands for "Sianel Pedwar Cymru" which is Welsh for "Channel Four Wales (C4W)".
In 1988, the ident changed to a computer-generated ident featuring an animation of the streamlined S4C logo, the colours of the logo were blue, green and red and the font was "Bodoni". The early 1990s saw a more "traditional" ident from S4C, depicting a piece of Welsh slate with colour blue green and red washing over the letters S4C.
On 7 March 1995, S4C introduced a new logo, with a red tilde resembling a dragon's tongue at the end of the S4C wordmark and the font was "Futura". Although no actual dragons appear in these idents, they nevertheless have a them of fire - for example a bin that burps flames and a fan that spreads flames - as symbolic of a dragon.
This logo was introduced on 18 January 2007. It was part of a total rebrand of the channel made by Proud Creative. In the rebrand, stereotypical Welsh icons such as dragons were avoided in favour of an "inherently Welsh" tone.
A new S4C logo and brand developed by Sugar Creative Studio was introduced on 10 April 2014; the new design was developed around a concept of providing "context" to S4C's target audience and programming. The design revolves heavily around a trapezoidal shape used within the channel's new logo, which is prominently used within aspects of the channel's overall marketing and branding.
