IDC Reports Notable Growth in Shipments of Client Operating Environments in 1998

FRAMINGHAM, Mass., January 18, 1999 — International Data Corporation (IDC) estimates that 1998 worldwide shipments of client operating environments increased to 87 million, up 10 percent from 1997. This increase is notable compared to the 5.7 percent increase the year before. The Client Operating Environments, 1998 in Review bulletin reports preliminary 1998 shipment data for all major COE’s and provides analysis of the marketplace.

"Microsoft Windows products continue to lead the market for new shipments of Client Operating Environments in CY 1998; to no one's surprise. However, a slight resurgence by Apple and continued success of the Linux operating system are impressive and noteworthy for CY 1998," said William Peterson, research manager, Client Operating Environments. "The success of the Linux Operating System market can be partially attributed to a number of application vendors announcing and/or bolstering their support for Linux in CY 1998."

The large growth in overall shipments can be attributed to several factors including:

-Microsoft Windows 95 products continued success.

– Organizations acceptance of Windows NT Workstation as a viable choice as an operating system for every day use.

– Linux has bolstered an otherwise ignored and slightly elusive &Other Category. IDC believes that a growing number of “Anything But Microsoft,” (ABM) proponents helped to improve industry recognition for Linux as a Client Operating Environment.

– Apple’s revamped Mac OS strategy has spurred an up turn in shipments. Apple's resurgence was surprising, as initial IDC estimates had Apple Operating System shipments continuing a downward trend. Apple's successful introduction of the iMac and a revamped MacIntosh Operating System strategy contributed to the improvements in Apple operating system shipments in 1998.

IDC believes that for 1999, one of the main influences on new COE shipments will be the availability of Windows 2000. Also, for 1999, IDC sees continued interest and growth for the entire Linux market.
