Here I share some of the history of Sony Ericsson.

Sony Ericsson is a joint venture established on October 3, 2001 by the Japanese consumer electronics company Sony Corporation and the Swedish telecommunications company Ericsson to make mobile phones. The stated reason for this venture is to combine Sony’s consumer electronics expertise with Ericsson’s technological leadership in the communications sector.

Both companies have stopped making their own mobile phones.
Sony was a marginal player in the worldwide cell phone market with a share of less than 1 percent in 2000. It was also struggling in this area with losses but wanted to focus more in this area. In April 2001, Sony confirmed that it was in talks with Ericsson for a possible collaboration in the handset business. This was soon after Toshiba and Siemens had announced plans in November 2000 to work together on handsets for 3G mobile networks.

By August 2001, the two companies had finalized the terms of the merger announced in April. The company was to have an initial workforce of 3,500 employees
