Sony Ericsson is a joint venture established in 2001 by the Japanese consumer electronics company Sony Corporation and the Swedish telecommunications company Ericsson to make mobile phones. Both companies have ceased making their own mobile phones. The reason for this merger is to combine Sony's global consumer marketing expertise with Ericsson's technological leadership in the communications sector.

Ericsson was forced to close down following a fire in Philips chip factory but was saved by Sony corporation and as a result they joined hand. Sony Ericsson mobiles in India, announced its first joint products in March 2002 and now has a full product portfolio covering all target groups.


Its first series was T series which included low budget phones. Its J series has good sound quality, they are amazingly small and are without camera. Sony Ericsson recently introduced the Walkman-branded W series music phones.
