The document discusses the history and development of graphical user interfaces (GUIs) from 1945 onwards. It mentions early concepts like Vannevar Bush's memex and hyperlinks in 1945 and Ivan Sutherland's Sketchpad in 1963, considered the first GUI. It then outlines key milestones like Doug Engelbart's "mother of all demos" introducing the mouse and windows in 1968 at Xerox PARC, the development of the desktop metaphor in the 1970s, and the launches of early commercial GUIs on platforms like the Apple Lisa in 1983 and the Apple Macintosh in 1984 which popularized the GUI paradigm.
