Swingometer

From Wikipedia, the free encyclopedia

The swingometer is a device that shows the swing from one party to another on British election results programme. The first outing on British television was during a regional output from the BBC studios in Bristol during the 1955 general election (the first UK general election to be televised) and was used to show the swing in the two constituencies of Southampton Itchen and Southampton Test.

Following this use in 1955, the BBC adopted the swingometer on a national basis and it was unveiled in the national broadcasts for the 1959 general election with Bob McKenzie in charge. This swingometer merely showed the national swing in Britain but not the implications on that swing on the composition of parliament. These issues were not addressed until the 1964 general election.

The swingometer for that election showed not only the national swing, but also the implications of that national swing. So for instance, a 3.5% swing to Labour would see Labour become a majority government whilst any swing to the Conservatives would see Sir Alec Douglas-Home reelected as Prime Minister with a huge parliamentary majority. In the end the result was a Labour overall majority of 3, and so when the United Kingdom general election, 1966 came around, a new element had to be added (namely the prospect of a hung parliament).

At the 1970 general election, the swingometer entered the age of colour television and showed the traditional party colours of red for Labour and blue for Conservative and had to be extended due to the success of the Conservative party at that election.

However, following the success of the Liberals in the by-elections held between the 1970 and February 1974 general elections, the swingometer was reduced in scale to just a small standby as the computers used by the BBC was deemed more reliable. As the Liberal Party reduced in importance the swingometer was brought back for the United Kingdom general election, 1979 but for the 1983 and 1987 general elections computers were introduced to show changes in support in both map and graphic form.

The swingometer was brought back for the 1992 general election covering the whole side of the election studio and also had to be manhandled by at least four technicans as well as Peter Snow who had taken over the election graphics role following the death of Bob McKenzie. This swingometer was a too big for comfort and in 1997 started on a shrinking process and was changed from an actual swingometer to a virtual reality swingometer. For the 2001 general election the graphic was reduced further. Following a few experiments in the United Kingdom local elections in 2003 and 2004 the swingometer for the next election in 2005 was held on virtual structs as well as swingometers for the Labour and Liberal Democrats parties.
