The company was formed by Henry Walton Smith and his wife Anna in 1792 as a news vendor in London. It remained under the ownership of the Smith family for many years and saw large-scale expansion during the 1970s as the company began to diversify into other markets. Following a rejected private equity takeover in 2004, the company began to focus on its core retail business. It was the first retail chain in the world, and was responsible for the creation of the ISBN book identifier.
