SEATTLE, WA, April 20, 1999 -- RealNetworks(TM) (Nasdaq: RNWK), the recognized

quarter of 1998. This represents the 15th consecutive quarter of sequential
revenue growth. Net loss for the first quarter of 1999 was $0.7 million, or
($0.02) per share, compared to a pro form net loss for the first quarter of 1998
of $2.2 million, or ($0.07) per share (excluding a one-time charge for
in-process research and development from the March 1998 acquisition of Vivo
Software, Inc.).

        The Company also announced that its board of directors approved a
two-for-one split of its common stock. Shareholders will receive one additional
share for every share held on the record date of April 27, 1999. The additional
shares will be mailed or delivered on or about May 10, 1999, by the Company's
transfer agent, ChaseMellon Shareholder Services.

        "This was another successful quarter for RealNetworks," said Rob Glaser,
Chairman and CEO of RealNetworks, Inc. "New partnerships with @Home and Enron
are taking us strategically into the coming age of broadband media delivery. Our
enhanced RealGuide is a significant improvement in the way we connect consumers
with the increasing volume of programming that is broadcast on the Web. Our
momentum continued in April, with announcements of our partnership with IBM and
our pending acquisition of Xing Technology, both of which prepare RealNetworks
for a strong entry into the digital media distribution market.
