In 1989, Ericsson's Radio Systems division formed a joint venture company with General Electric under the name of Ericsson GE Mobile Communications. The company consisted of all mobile phone activity of both companies in Sweden and USA. Its products were sold mostly under both Ericsson HotLine (later just Ericsson in 1992) and GE brands. Due the severe cooperation problems between two companies and inability to break to the US cellular phone market, GE eventually left out of the joint venture in 1993, making this company a wholly owned subsidiary of Ericsson.
