ITV 50 was a special event around September 2005, celebrating the 50th anniversary of the ITV terrestrial television network's launch; the official anniversary was stated as being 22 September, the anniversary of the first ITV region, Associated-Rediffusion, beginning broadcasts.
Other regions, though not launched in 1955, were also involved in the celebrations, broadcasting network and local ITV 50 celebration programming. All ITV plc regions received ITV 50 presentational material including branded graphics and station idents. STV (then Scottish and Grampian) and UTV screened much of the networked ITV 50 content, using some of the ITV 50 presentation.
