Whether we believe it is right or not, many of us have become accustomed to the fact that a large number people download copyrighted material regularly using Peer-to-Peer file-sharing software. As a result, the entertainment industry is losing billions of dollars in revenue, and is suffering from the infringements of many copyrights. Who should be held responsible for this? Is it the fault of the people who misuse the software, or is it perhaps the fault of the software distributors for allowing this to take place? The recent case of MGM Studios, Inc. v. Grokster, Ltd examined these issues.
