Two letters C inside a circle, marking a work offered under a CC licence.
Also known as: CC logo, Creative Commons symbol
The double-C in a circle marks a work released under one of the Creative Commons licences. On its own it says a licence applies but not which one — the accompanying condition marks carry that, and without them the badge is incomplete.
Identifies a work made available under a Creative Commons licence, the family of public copyright licences published by the Creative Commons organisation.
Carries no licence terms by itself. Which permissions apply is given by the condition marks shown with it — attribution, share-alike, non-commercial, no-derivatives — so a bare CC badge does not tell a reader what they may do.
The organisation was founded in 2001 to offer an alternative to all-rights-reserved copyright, and the licences have been through several versions since.
A circle outline enclosing two capital letter C shapes set side by side, each an open arc facing right.
A single C in a circle asserts copyright; two C shapes mark a licence that grants permissions under that copyright. The Creative Commons badge does not waive copyright.
Both are built from circles.
