Swedish telephone equipment manufacturer founded in 1876 (as a telegraph equipment repair shop) by Lars Magnus Ericsson. In the early 20th century, Ericsson dominated the world market for manual telephone exchanges and was late to introduce automatic equipment. The world's largest ever manual telephone exchange, serving 60,000 lines, was installed by Ericsson in Moscow in 1916. Throughout the 1990s, Ericsson has held a 35--40 % market share of installed cell phone systems.
