Panasonic

Panasonic is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Panasonic rather than just read about it. In short: Panasonic Holdings Corporation is a Japanese multinational electronics manufacturer, headquartered in Kadoma, Osaka, Japan. It was founded in 1918 as Matsushita Electric Housewares Manufacturing Works in the Fukushima ward of Osaka by Kōnosuke Matsushita.

Key takeaways

Panasonic belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Panasonic to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Panasonic from memory before moving on to harder problems.

Reference excerpt

Panasonic Holdings Corporation is a Japanese multinational electronics manufacturer, headquartered in Kadoma, Osaka, Japan. It was founded in 1918 as Matsushita Electric Housewares Manufacturing Works in the Fukushima ward of Osaka by Kōnosuke Matsushita. The company was incorporated in 1935 and renamed Matsushita Electric Industrial Co., Ltd., and changed its name to Panasonic Corporation in 2008. In 2022, it reorganized as a holding company and adopted its current name. In addition to consumer electronics, for which it was the world's largest manufacturer in the late 20th century, Panasonic produces a wide range of products and services, including rechargeable batteries, automotive and avionic systems, industrial equipment, as well as home renovation and construction. The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX 100 indices, with a secondary listing on the Nagoya Stock Exchange. In 2025, the World Intellectual Property Organization (WIPO)’s Annual PCT Review ranked Panasonic number of patent applications published under the PCT System as 6th in the world, with 2,094 patent applications being published during 2025.

Corporate name From 1935 to October 1, 2008, the company's corporate name was "Matsushita Electric Industrial Co., Ltd." (MEI). On January 10, 2008, the company announced that it would change its name to "Panasonic Corporation", in effect on October 1, 2008, to conform with its global brand name "Panasonic". The name change was approved at the shareholders' meeting on June 26, 2008. In 2022, Panasonic announced a reorganization plan which split the company into Panasonic Holdings Corporation (the former Panasonic Corporation) and conversion of its divisions into subsidiaries; the Lifestyle Updates Business Division being the division that took the Panasonic Corporation name after the reorganization. The reorganization took effect on April 1, 2022.

Brand names Panasonic Corporation currently sells virtually all of its products and services worldwide under the Panasonic brand, having phased out the Sanyo brand in the first quarter of 2012. It uses the marketing slogan "A Better Life, A Better World". The company has sold products under a number of other brand names during its history. In 1927, Matsushita adopted the "National" brand name for a new lamp product. In 1955, the company began branding audio speakers and lamps as "PanaSonic" for markets outside of Japan. Further refined to Panasonic, taken from the words "pan" – meaning "all" – and "sonic" – meaning "sound", the brand was created for the Americas because the National brand was already registered by others. Panasonic also sold the first bread machine. The company began to use the brand name "Technics" in 1965 for audio equipment. The use of multiple brands lasted for some decades. While National had been the premier brand on most Matsushita products, including audio and video, National and Panasonic were combined as National Panasonic in 1997 after the worldwide success of the Panasonic name. In 1974, Motorola sold its Quasar brand and facilities to Matsushita. In May 2003, the company announced that Panasonic would become its global brand, and launched the global tagline "Panasonic ideas for life." By March 2004, Matsushita replaced the National name for products and outdoor signboards, except for those in Japan. They would eventually phase out the National brand in Japan by March 2010. In September 2013, the company adopted a new tagline to better illustrate its vision: "A Better Life, A Better World." The Chinese company Shun Hing Electric Works and Engineering Co. Ltd (信興電工工程有限公司) has sold imported Panasonic and National branded products under the brand name Rasonic since the Matsushita Electric Industrial era. They have also sold MEI and Panasonic products under their original brand names. In June 1994, Panasonic Shun Hing Industrial Devices Sales (Hong Kong) Co., Ltd. (松下信興機電(香港)有限公司) and Panasonic SH Industrial Sales (Shenzhen) Co., Ltd. (松下电子机电(深圳)有限公司) were established by a joint venture between Matsushita Electric Industrial and Shun Hing Group respectively, making Rasonic a product brand for MEI and subsequently the Panasonic Corporation. In September 2014, Panasonic announced the revival of the Technics brand, first in European markets in December of that year.

Worked examples

Example 1 — a first encounter with Panasonic

Start with the simplest possible case. Write down what Panasonic claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Panasonic before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Panasonic ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Panasonic

In research: Panasonic appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Panasonic in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Panasonic is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s initial public offerings, Battery manufacturers, Capacitor manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for Panasonic outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Panasonic in simple terms?

Why does Panasonic matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
