The British Red Telephone Box is a familiar sight on the streets of this country; it is a very British icon.
The first Red Telephone Box design was introduced in 1924, and by 1968 the Post Office had introduced its eighth design for a National Telephone Kiosk.
Over the last eighty years the Telephone Box has become a symbolic piece of street architecture, whether in our rural villages or on our urban highways.
The first Telephone Box was the K1, introduced in 1920 and a few years later a national competition was held to find a design for a new national telephone box.
The winning design was submitted by the pre-eminent British architect Sir Giles Gilbert Scott. Though in the latter years of the twentieth century many were replaced by modern-glass kiosks, the Telephone Box occupied such a place in people's affections that those left were preserved and many were given listed-status protecting them from removal and destruction.
Today, the Telephone Box remains a welcome sight on the streets of the Britain. In March 2006, as part of a competition organized by the Design Museum and BBC Television to find Britain's favorite design icon since 1900, the Telephone Box was placed in the top ten by the British public.
