Sony Selects Spyglass to Provide Internet Software

World's Consumer Electronics Leader Selects Spyglass Software for Use in
Future Information Appliances

NAPERVILLE -- Tuesday, April 20, 1999 -- Spyglass� Inc. (NASDAQ: SPYG)
announced today Sony Corporation (NYSE: SNE) has licensed Spyglass Internet
software for use in future information appliances, such as advanced digital
set-top devices. Specifically, Spyglass Device Mosaic, an embedded Web
browser, and Spyglass ThinGUI Library, a small footprint graphics library,
have been licensed to Sony.

According to International Data Corporation (IDC), the global market for
information appliances will grow to 55.7 million annual unit shipments in
2002, resulting in a 76 percent annual growth rate from 1998-2002. Much of
this momentum can be attributed to the growth in NetTV, gaming devices and
smart handheld products. By 2001, IDC expects there will be almost 11.5
million NetTV products alone shipped annually, attributing the growth to the
recent efforts of the U.S cable industry for deploying interactive
television and high-speed Internet access.

The growth potential of broadband Internet access through digital cable
relies on the ability to enhance the viewer's experience through creating
Internet browsing applications such as electronic programming guides (EPGs),
video-on-demand services, pay-per-view, e-commerce, and a variety of other
revenue generating applications and services.

"Sony leads the way in the technical convergence of audio, video, computing
and communications," said Randy Littleson, Spyglass vice president and
general manager. "Their expertise in digital consumer electronics and
powerful retail brand, complement our power to provide quality Internet
solutions to the world's leading device manufacturers. Expertise from both
companies will be extremely vital in the development of the next generation
of information appliances."
