The Exchange Telegraph Co. Ltd. (also known as EXTEL) was created in March 1872 specifically to distribute financial and business information from the Stock Exchange and other commercial markets direct to subscribers. The company established ticker tape telegraph machines in offices, gentlemen's clubs, banks etc. and provided a continuous stream of commercial information to them. It introduced a parliamentary service in 1876, a general news service in 1879 and a legal service in 1891. The business was so successful that by 1906 they had opened ten other branches outside London. The company continued to grow and improve, becoming increasingly more efficient. It added a faster financial service in 1907 and began operating a worldwide news service in 1913, with a separate sports service included in the 1930s. Over the course of its history, Extel (the name coming into common use for the company in the 1950s) grew into one of the leading news agencies, provider of financial information and associated businesses. Among the many notable achievement were 'Extel Cards', the very first corporate snapshots/tear-sheets with brief data on profit and loss, employees, business activities and executive management. Extel Cards, naturally in hard copy, were first produced in 1922.
