tractor of telephone instruments to the Stockholms Allmanna Telefonaktiebolag, established in 1883 with the object of installing and operating entire telephone exchanges and networks,the business expanded rapidly. In the early nineties the concern began to interest itself in the introduction of its appliances and system outside of Sweden. The first to come under its influence were the neighbouring countries Finland, Norway, Denmark and Russia. Other European and overseas-countries followed in rapid succession as users of the Ericsson inventions.

Of complete exchanges and networks supplied and installed abroad by the company may be mentioned those of Warsaw, Moscow and Mexico City. A great many of the central exchanges in important towns of the world are built by the company: Copenhagen, The Hague, Amsterdam, Rotterdam, Paris, Calcutta, Johannesburg, Singapore, Shanghai, etc. — to mention only a few — and at the present the Ericsson telephones have penetrated to the most remote countries.
