contents	Multiple news sources over the years have reported on the problematic effects of Digital Rights Management, yet there are no reforms for DRM development, simply removal. The issues are well-known to the public, frequently repeated even when addressed: impact on the software and to the devices that run them. Yet few, if any, have discussed it in recent years, especially with the intent of eliminating the shown issues. This study reviews Digital Rights Management as a general topic, including the various forms it can take, the current laws that affect DRM, and the current public reception and responses. This study describes the different types of DRM in general terms and then lists both positive and negative examples.
