Source-derived summary

Sony Ericsson Mobile Communications AB, was a multinational consumer electronics and telecommunications company, best known for its mobile phone products. The company, originally a joint venture between Sony and Ericsson, marketed products under the "Sony Ericsson" brand from 2001 until 2012, when Ericsson sold its share to Sony, with products hereafter being branded as "Sony". From its inception until 2018, previous presidents of Sony Mobile included Katsumi Ihara, Miles Flint, Hideki Komiyama, Bert Nordberg, Kunimasa Suzuki and Hiroki Totoki. After that, Mitsuya Kishida served as its last president until it was integrated into Sony Corporation in 2021.

The alliance between Swedish telecom giant Ericsson and Japanese electronics giant Sony was formed to help Ericsson Mobile recover against competitors in the mobile phone market, while for Sony it gave the opportunity to grow in the field of cellular communication, where it had only a minor presence. Products and development was done with contributions from both parties: the company itself was based in London, England, with its design centre in Lund, Sweden, and other research and development facilities in Beijing, China; Tokyo, Japan; and San Francisco, United States. The Sony Ericsson T68i was the first GSM phone released under the joint venture since its launch. After the Sony acquisition, the company, now as Sony Mobile, moved its headquarters to Tokyo, Japan.

Some of the most notable phones produced by Sony Ericsson include the T610, the K800i (Cyber-shot branded), the W810 (Walkman-branded), and the Xperia arc S. Sony Ericsson was also the main user of the UIQ smartphone platform, but beginning in 2010 had switched over entirely to Android. After the end of the joint venture, the Xperia sub-brand of Android smartphones would be the only handsets under the Sony brand, although Sony Mobile also developed tablet computers (Xperia Tablet), smartwatches (Sony SmartWatch) and fitness trackers (Sony SmartBand).

Editorial summary

“Sony Mobile” enters the record as japanese telecommunications company owned by Sony. Crown Archives preserves that source wording while asking what Sony, Mobile and Japanese can confirm, complicate or overturn.

Editorial reviewA useful synthesis for locating the documentary relationships between formal authority, participants and affected communities. The current lead gives the account dated anchors—2001, 2012, 2018, 2021—that can be checked directly. The linked authority record independently contributes the date 2001-10-01. Its strongest next move is a source search built around Sony, Mobile and Japanese.
Editorial analysis

Why this record matters

“Sony Mobile” is worth following because a concise public description often conceals a longer documentary argument. Here, Sony, Mobile and Japanese provides the most credible route into that argument.

Evidence profile

The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q376692. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2012, 2018 and 2021.

Critical limits

Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
