INTERNET APPLICATION USAGE CONTINUES TO DECLINE, ACCORDING TO
NIELSEN//NETRATINGS


NEW YORK September 29, 2003 Nielsen//NetRatings, the global standard for Internet audience
measurement and analysis, reports that file-sharing application usage from home continues to decline
since the Recording Industry Association of Americas initial warning that people who illegally downloaded
music would be sued or prosecuted. As the RIAA begins filing hundreds of lawsuits against individuals
downloading music, usage of popular file-sharing applications are at an all-time low.

Since the week ending June 29, traffic to the KaZaA application has declined 41 percent from 6.5 million
unique visitors to nearly 3.9 million unique visitors for the week ending September 21 (see Table 1).
Despite the declines in usage, KaZaA remains the most popular file-sharing application for Americans
with millions of users. Traffic to the Morpheus application decreased from 272,000 unique visitors during
the week ending June 29, to the 261,000 visitors during the week ending September 21. BearShare and
iMesh attracted 192,000 and 255,000 visitors, respectively, during the week ending June 29 and fell
below Nielsen//NetRatings reporting levels during the week ending September 21.

The RIAA is clearly sending a strong message to American Web users and the message appears to be
working, said Greg Bloom, senior Internet analyst, Nielsen//NetRatings. "With hundreds of individuals
facing real lawsuits, the threat to music file sharers is very serious."
