The London Underground started out as several separate train lines transporting passengers in central London. The original idea of putting the trains underground came about because of the need to transport passengers from the main lines further into central London. Because of constraints and overcrowding, the grand train lines could only penetrate the outskirts of London. In the beginning, any railway tunneling underground had to buy the buildings that it passed under. This was done because many felt that the underground digging undermined the foundations of buildings. This explains why many of the earliest Underground lines followed major streets. There were no buildings above, therefore, the railway saved money. In 1912 Frank Pick was appointed the head of the office of commercial manager for expanding Underground. During his time in this position, several new acquisitions were made including bus and rail lines. Pick's job was to integrate these acquisitions into one coherent system. In order to increase ridership, Pick advertised the Underground with posters he commissioned by artists. Posters advertised destinations that could be reached by using the Underground. He went further to create a logo which would be easily recognized by the public. Even though every station was different architecturally and aesthetically, Pick created uniformity through signage and easily recognizable symbols of the Underground. The Underground became an essential part of London culture. Phrases such as "Mind the Gap" became synonymous with the Underground. Then in April of 1996 a dashing young man named Scott Carter visited London with his high school band and was inspired to create this site, the rest is history. As a visitor, the Underground is many times the first thing one experiences in London. It carries to and from the airports and is one of the easiest ways to get about, especially if one doesn't have a car. The Underground is like the veins of a living being. It carries life throughout the arteries of London. Without this valuable link, Londoners would have to resort to the above ground transportation.
