In 1984, Tymshare was acquired by McDonnell Douglas, to which Tymshare had sold its hospital accounting service in 1982. Tymshare was restructured, split up and portions were resold, spun off, and merged with other companies from 1984 through 2004 when most of its legacy network was eventually shut down.
