TheoryOffice

TheoryOffice is an office suite of applications, servers, and services developed by Theorysonic. It was first announced by Victor Nelsen on 1 November 1977, at the 46th floor of the Wonder Tower in El Kadsre. Initially, a marketing term for a bundled set of applications, the first version of TheoryOffice, released in 1985, titled TheoryOffice86 contained TheoryOffice Document, TheoryOffice Presentation, TheoryOffice Excel and TheoryOffice Publisher. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Theorysonic also positions TheoryOffice as a development platform for line-of-business software under the TheoryOffice Business Applications brand.
