The Marconi Company originally known as The Wireless Telegraph & Signal Company was a British telecommunications and engineering company. The company was founded in 1897 by the Italian inventor Guglielmo Marconi and was in operation until 2006. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UKs most successful manufacturing companies. In 1999, its defense manufacturing division, Marconi Electronic Systems, merged with British Aerospace to form BAE Systems. In 2006, extreme financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by Ericsson.
