graphical user interface (GUI)

Computer display format that allows the user to select commands, call up files, start programs, and do other routine tasks by using a mouse to point to pictorial symbols (icons) or lists of menu choices on the screen as opposed to having to type in text commands. The first GUI to be used in a personal computer appeared in Apple's Lisa, introduced in 1983; its GUI became the basis of Apple's extremely successful Macintosh (1984). The Macintosh's GUI style was widely adapted by other manufacturers of personal computers and PC software. In 1985 Microsoft Corp. introduced Windows, a GUI (which later grew into an operating system) that gave MS-DOS–based computers many of the same capabilities as the Macintosh. In addition to being used for operating-system interfaces, GUIs are used in other types of software, including browsers and application programs.

The Graphical, Paper and Media Union (GPMU) was a trade union in the United Kingdom and the Republic of Ireland between 1992 and 2005. Having been formed from the merger of SOGAT and the National Graphical Association, it claimed to be the world's largest media union, and had over 200,000 members working in the print, publishing, paper, IT and media industries. The sole General Secretary of the GPMU was Tony Dubbins, the Deputy General Secretary of the GPMU was Tony Burke.

Facing a decline in membership, in February 2004, GPMU opened merger negotiations with Amicus. In August 2004, results of a ballot of all members were released, showing 86% of members in favour of merger. The formal merger took place in early 2005, and GPMU became the semi-autonomous Graphical, Paper and Media industrial sector of Amicus. Tony Dubbins became the Deputy General Secretary of Amicus and Tony Burke became Assistant General Secretary of Amicus. Tony Dubbins is also the Chair of TULO. Amicus merged with the Transport & General Workers Union in May 2007 to form Unite The Union.
