WHEN:    Wednesday, September 24, 2003

DETAILS: Bill Rose and Larry Rosin will discuss how Internet
         Broadcasting consumption has become a mainstream activity
         amongst consumers today. They will also explore the consumer
         purchase behavior of "early adopters," people who are among
         the first to buy or try new products or services.

         Other new findings from the study include:

            --  Online purchasing has nearly doubled in the past three
                years;

            --  Nearly two-thirds (61 percent) of people who tune to
                Internet audio and 59 percent of those who watch
                Internet video prefer free programming supported by
                advertising versus other business models;

            --  A quarter of those with Internet access at home use
                software programs to block other forms of Internet
                intrusions;

            --  Despite predictions of a plateau, the percentage of
                Americans with Internet access in any location (home,
                work, school, public library) increased to 80 percent.

    In addition, Mr. Rose and Mr. Rosin will address the latest data
on the impact of broadband/internet connections on media and consumer
usage; awareness and usage of satellite media; and the internet as a
motion picture promotion vehicle and information resource.
