The rise of social media platforms worldwide has sparked a new movement of user-generated content. This trend raises concerns about copyright protection, infringement, and fair use on sites such as Facebook, TikTok, and Pinterest. Copyright infringement occurs on social media when individuals share, repost, or alter protected content without the necessary permission or credit. This problem is made worse by the simplicity of sharing digital material, the unclear limits between fair use and infringement, and the international aspect of social media, which complicates enforcement across different jurisdictions. This paper addresses the intricate issues of copyright infringement and the definitions of fair use within social media. The analysis breaks down the various criteria for demonstrating fair use and attempts to align them with the context of social media through several legal cases. It also explores the obstacles users encounter when trying to assert their copyright rights. Additionally, it highlights the challenges copyright holders face regarding the violation of their exclusive and moral rights. Ultimately, this paper aims to present a clearer perspective on the fair use doctrine in the context of the Internet. By examining the legal framework, assessing its practical implications, and identifying possible solutions, this paper aspires to convey to both creators and users that nurturing an online environment where creativity can thrive while maintaining respect for intellectual property rights is essential for progress.
