Many people see unauthorized music downloading as harmless and don't fully understand its consequences. Illegal downloading presents a serious issue on college campuses and can be costly to the university administration in terms of resources, such as excessive use of bandwidth and time spent responding to infringement notices sent by the RIAA (Recording Industry Association of America). The RIAA is very active in enforcing DCMA for their clients, and UC assists in the enforcement of these complaints. For more information on how the RIAA works with Universities, go to the FAQ's on the RIAA site. Considerable progress has been made in the growth of legitimate music services, the adoption of technological measures and education and enforcement programs on campuses. Use of legitimate services on campus has grown exponentially. Nearly 130 universities offer their students access to a legal music service and a substantial increase of additional schools joining this list is expected in the coming months.
