 The company's distinctive corporate image, including official Underground roundel and iconic tube map designed by Harry Beck are also considered major contributions to visual art, and several of the network's stations have been decorated with artistic tiling or murals depicting local historical or traditional themes.Launched in 2000, previously known as "Platform for Art", London Underground's art programme aimed to continue the company's association with the arts and "create an environment for positive impact and to enhance and enrich the journeys of the passengers that are its audience".
