Let me correct your question first. Sony’s full name is Sony, not Sony Ericsson

Sony is a world giant spanning the fields of digital, daily necessities, and entertainment. It is headquartered in Tokyo, Japan.

The main companies under its subsidiaries are

SCEI (Sony Computer Entertainment, PSP, PS2, and PS3 are all works of this company)

SPE (Sony Pictures Entertainment) , its subsidiaries include Columbia Pictures, MGM Films, Sony Classic Movies, Sony Online Entertainment, AXN Animax, etc. Among them, Columbia and MGM account for more than 50% of the Hollywood market, and 007, Spider-Man, etc. are all produced by them. (Part 2)

VAIO (Sony Computer brand under Sony)

BRAVIA (TV brand under Sony)

Sony Ericsson is a subsidiary of sony and Ericsson. The 50%-controlled joint venture is headquartered in London and registered in the UK. It can be considered a European company

Sony Ericsson has not registered the Sony Ericsson brand. Sony Ericsson is the abbreviation given to Sony Ericsson. , and only produces mobile phones,,,

The Sony Ericsson company in Guangzhou that produces MP4 is actually trying to infringe on the Sony Ericsson trademark. It has no relationship with Sony Ericsson (before this company was established, Everyone is used to abbreviating Sony Ericsson as Sony Ericsson)

At the beginning of this year, Sony completed the acquisition of 50% of Ericsson's shares. Sony Ericsson became a wholly-owned subsidiary of Sony, the brand was changed to Sony Mobile, and the logo was changed to Sony

To put it simply, Sony Ericsson is Sony’s illegitimate son. They just met and returned to the Suo family this year...
