- Shared Medical Systems (SMS) was a pioneering healthcare IT company founded in 1969 by ex-IBM employees Jim Macaleer, Harvey Wilson, and Clyde Hyde that developed one of the first electronic health record and hospital information systems called SHAS.
- SMS grew rapidly over the 1970s and 1980s from a few employees and hospitals to over 7,000 employees and annual revenues of over $1 billion serving thousands of hospitals by providing the core SHAS system and additional applications on IBM mainframe computers.
- SMS was acquired by Siemens in 2000 for $2 billion after generating over $22 billion in total revenues and leaving a lasting impact on digitalizing healthcare records and systems.
