Where else in London is there to shop on a warm afternoon other than on Oxford Street itself. Home to around three hundred different shops, Oxford Street is a bustling street heavy with foot traffic of people of all backgrounds and ethnicities. Before this street was used for commercial use for the public and shops, this street was used for public hangings and other forms of execution. Once the street was reformed into a road with revenue, it began to attract all sorts of characters: prostitutes, beggars and traders. The street eventually became a hive of businesses and consumers. 

Today, Oxford Street still is used for consumer businesses; mostly businesses that are more modern, but there are still older trading houses that date back to the early 1900's. Also more modern engineering: such as more lights at night, more cars, cleaner street, etc.
