Description

The U.S. Copyright Office is amending its regulation governing the group registration option for news websites. The final rule clarifies the definition of a "news website" to specify the works eligible for this option, accommodating a range of modern news publishing practices. The amendment allows news websites to focus on a variety of subjects within a topic area rather than requiring coverage of a broad range of news on all subjects. This rule is effective August 13, 2026, and aims to expand eligibility and encourage registration under the group registration option for news websites.
