i) Press release announcing SONY CORPORATION OF AMERICA TO ACQUIRE GRACENOTE


                SONY CORPORATION OF AMERICA TO ACQUIRE GRACENOTE

ACQUISITION BOLSTERS PORTFOLIO OF CONTENT, TECHNOLOGY AND SERVICE GROUPS FOCUSED
                        ON ACCELERATING DIGITAL COMMERCE

April 22, 2008 - New York, NY - Sony Corporation of America (SCA) announced
today that it has signed a merger agreement with Gracenote, Inc. Sony will pay
approximately $260 million plus other contingent consideration.

"Gracenote is a global leader in technology and services for digital media
identification, enrichment, and recommendation, and these capabilities will be
essential to the next wave of innovation in content, services, and consumer
electronics," said Tim Schaaff, SCA Senior Vice President, Software. "Sony sees
tremendous growth potential in developing Gracenote as a separately run business
unit, and by broadly embracing Gracenote's platforms, Sony expects to
significantly enhance and accelerate its own digital content, service, and
device initiatives."

"We are very pleased to join Sony as its strategic vision is very much in line
with our own," said Craig Palmer, Gracenote CEO. "Having a closer connection
with the content and digital services community will accelerate adoption of
Gracenote technologies, and the relationship will also give us the resources
necessary to rapidly expand development of next generation products for the
industry."

Gracenote's existing business will continue to operate separately. As a wholly
owned Sony subsidiary, Gracenote will continue to develop new technologies in
existing as well as new areas of operation. The senior management team will
remain with the company.

Sony and Gracenote anticipate that the transaction will close in late May,
subject to certain regulatory and other approvals.
