Creative Commons is a non-profit organization internationally active in providing free licenses that creators can use in order to make their work available to the public. With the creative commons (CC) licenses, the creator has basically given others permission in order to use their work but under specific conditions.
Whenever a work is created, an article or a photograph was taken, there is a copyright that protects it so that it cannot be used in certain ways. On the other hand, the CC licenses allow the creator to choose how they would want others to use their creativity.

YouTube utilizes CC licenses in its content. With it, the content creators can grant others to use their work as sort of a standard. YouTube users can use the Creative Commons CC BY license in marking their videos. When they use the CC By license, the system will generate a signature to the video automatically. This indicates that you are using Creative Commons content and will show the source video’s titles below the video player. The creator retains the copyright of the video while others can reuse your video but under the terms of the license.
