USA Digital Millennium Copyright Act

1. Introduction

The Digital Millennium Copyright Act represents landmark legislation that shaped the modern digital content landscape. Enacted in 1998, the DMCA implements international copyright treaties while establishing crucial protections for both copyright holders and online service providers. The Act addresses the challenges of digital content protection and distribution in the internet age, creating a framework that balances creative rights with technological innovation.

The DMCA serves two primary purposes: protecting copyrighted works through anti-circumvention provisions and creating safe harbor provisions for online service providers. This dual approach has become increasingly important as digital content sharing and streaming services have become ubiquitous in daily life.
