Company history

Foundation and development: 1891–1930

On May 15, 1891, the company Philips & Co. was founded in Eindhoven, the Netherlands, by Frederik Philips and his son Gerard . The following year, the company's first products were incandescent lamps with ten workers . In the following years the company expanded and Gerard's brother Anton Philips joined the company in 1895. On August 29, 1912 Philips & Co. was transferred to a stock corporation (Dutch: Naamloze Vennootschap (NV)) and renamed NV Philips' Gloeilampenfabrieken .

In 1914 the research laboratory Philips Natuurkundig Laboratorium (NatLab) was founded in Eindhoven. This laboratory was operated in-house until 2012.

In 1918, Philips launched its first radio tube . At that time, 4,000 people were already working for Philips and sales organizations were set up in all of the world's major sales markets.

In 1920 the NV Gemeenschappelijk Benzit van Aandeelen Philips Gloeilampenfabrieken ( NV Benzit ) was established as a holding of the Philips Group. It was not until 1991 that the name NV Benzit was deleted and the name of the holding company changed to Philips Electronics NV .

In 1926 the pentode tube for radios was invented in the Natlab research laboratory and in the same year Deutsche Philips GmbH was founded in Berlin . When it was founded, the German delivery program comprised four products: loudspeakers , rectifiers , power supply units and replacement tubes.

In 1927 the company entered medical technology. After the first research in the field of X-ray tubes began at Philips in 1917, X-ray tube production began three years later, in 1920, with the result of the first Philips X-ray tube in 1922. On April 17, 1927, the CHF Müller company, its owner since 1909 the chemist Dr. Max S. Liebermann, a nephew of the painter Max Liebermann , and the subsidiary Radio Röhrenfabrik GmbH ("Valvo") became the property of Philips AG under the name "CHF Müller division of Philips GmbH". The combination of CHF Müller's many years of experience in the manufacture of X-ray tubes in Hamburg with the results of research into X-ray tubes in Eindhoven forms an important basis for Philips' later success in medical technology worldwide. The headquarters of Philips Medical Systems has been Hamburg since then . Another branch is located in Böblingen .

War and post-war period: 1930–1960

After the successful 1920s, Philips also had to struggle with the consequences of the global economic crisis and had to restructure its sales network.

In 1934, Philips opened a radio equipment factory in Aachen. For example, the radio sets "Aachen Super" and the first Philips dry shaver "Philishave" came from the factory . Both products contributed significantly to the success of Philips in Germany.

The company presented its first television sets in various European cities in 1928 . At that time, 45,000 people were employed by Philips. In 1939, the “Philishave” razor with a rotating shaving system was introduced, the basic principle of which has remained unchanged in Philips razors to this day.

The General German Philips Verwaltungs GmbH (Alldephi) was established to protect the rights of the Dutch parent company perceive. But the Second World War initially ended the further development of the company in Germany. The managing director of Philips in Germany, Theodor Graf von Westarp , had to give up his responsibility at the beginning of the war due to his opinion on the political situation in Germany.

During the Second World War, the Dutch plants were as so-called "enemy property" under German receivership . The Philips main factory in Eindhoven produced components and devices for the Wehrmacht and was therefore attacked several times by Allied aircraft during the war, and the headquarters were destroyed by bombs. In Aachen, production there initially ended with the evacuation of the city. In the Herzogenbusch concentration camp , prisoners were forced to produce for Philips.

After the end of the war, reconstruction began; in addition, further plants and branches were established worldwide. After the war, Count von Westarp, who was reinstated in his previous position by the Allies shortly after the end of the Second World War, took over the management of Deutsche Philips GmbH . In 1946 the head office was relocated from Berlin to Hamburg and a light bulb factory was founded in Aachen . As a result, the company developed into a versatile electronics and technology provider with activities in research, development, production and sales. In 1947 a glass factory was set up in Aachen and in the apparatus factory founded in Berlin in 1948, Philips started the production of radios, dry shavers, phono and tape recorders as well as electric shavers. The newly built apparatus factory in Wetzlar also started production in 1947 with the D78A radio receiver. Travel receivers and car radios , along with home receivers, were among the largest product areas. Production continued there until the end of the 1990s. In 1950 Philips entered the phonograms market and established the music division and founded its first subsidiary for vinyl recordings , the Philips Phonographic Industry . These activities resulted in a 50 percent participation in the Deutsche Grammophon Gesellschaft (later renamed PolyGram ). In 1951, Philips began producing televisions in the Apparate Factory in Krefeld . In the years that followed, Philips expanded its presence in both Hamburg and Aachen. Philips began developing and manufacturing semiconductors in Hamburg, and in 1954 the company began producing picture tubes in Aachen .

In 1955 the German Philips Research Center was founded in Aachen. As early as 1957, Philips expanded its research activities and founded the research laboratory in Hamburg.

At the 23rd German Radio Exhibition in Berlin in August 1963, Philips presented the Compact Cassette and the associated cassette recorder .

In 1967, the color television developed by Walter Bruch based on the PAL system was introduced in Germany. In the same year, the Philips subsidiary Valvo began series production of color picture tubes at the Aachen plant . The VHF ferrite antenna was developed in the Philips research laboratory in Aachen .

In the light sector , Philips was the first company to introduce compact, energy-saving fluorescent lamps in the early 1980s : the SL * lamp (1980) and the PL * lamp the following year.

In 1982 the Philips Communication Industry AG (PKI) was established, in which the areas of office and telecommunication were combined. In 1982 the compact disc , a joint development by Philips and Sony , came on the market in Europe and Japan. In 25 years, more than 200 billion CDs have been produced worldwide. In 1984 the research laboratory in Hamburg produced images of the human head with the help of magnetic resonance tomography , a diagnostic procedure without X-rays .

In 1986 the radio cassette recorder "Roller" came onto the market. The consideration of the device as a fashion item was also viewed very critically internally at Philips. The device was a great success, over 700,000 copies were sold within a short time at a price of 200 DM.

Reconstruction and departure: 1990 to today

In the 1990s there was a profound reorganization of the entire company. The company NV Philips' Gloeilampenfabrieken , existing since 1912, was changed in 1991 to Philips Electronics NV . In 1997, the company moved from Eindhoven to Amsterdam and the company was renamed Koninklijke Philips Electronics NV (Royal Philips Electronics NV) .

After German reunification , Philips invested in the new federal states and in 1991 took over both RFT Fernmeldewerk GmbH in Bautzen and Narva Speziallampen GmbH in Plauen , a global company in the field of vehicle lighting .

In the period that followed, new markets were opened up with the help of cross-sector partnerships: The first DVD came onto the market in 1997 in cooperation with partners . In 2000, Philips opened a high-tech X-ray tube factory in Hamburg. In 2001, Philips also took over the development and production center for patient monitors in Böblingen as part of the acquisition of the Healthcare Solution Group (HSG) from Agilent Technologies .

In 2002, the " Senseo " coffee machine was introduced in cooperation with the Dutch coffee producer Douwe Egberts . Beiersdorf ( Nivea ) supplied the emulsion for the Philips “Coolskin” dry and wet razor. Aachen has been the focus of research on organic light-emitting diodes (OLED) since 2004 . The DMC in Hamburg was supplemented by a new competence center for X-ray generators. In 2005, together with the brewery group InBev , the “PerfectDraft” home dispensing system was brought onto the market.

From 2006 the group concentrated on its core competencies in the areas of healthcare, lifestyle and technologies; The semiconductor business was transferred to an independent company, now NXP , and 80.1% of the shares were sold to a financial investor consortium. In autumn 2006, Philips expanded its portfolio by taking over the laser diode specialist ULM Photonics. In September 2007 Philips announced its “Vision 2010” strategy. At the end of December 2007, Philips announced the largest acquisition in the company's history with the takeover of the US company Respironics. This significant step in the Group's health strategy gave Philips the global leadership position in home health solutions in the sleep apnea monitoring and treatment market and in home ventilation solutions.

In January 2008, the business structure was divided into three core segments: Lighting, Healthcare and Electrical Appliances, which consists of the former Consumer Electronics, Small Domestic Appliances and Speech Processing divisions . The company logo has been redesigned. Also in 2008, the Speech Recognition Systems division was sold to Nuance Communications . The Speech Processing division, which belongs to Consumer Lifestyle , remained with the company and continues to have its headquarters in Vienna . In February 2009, Philips opened the expanded returns and recycling center in Hamburg. With this expansion, CO 2 emissions can be reduced by up to 1200 tons per year.

On October 5th, 2009, the employees of the Aachen research laboratory were informed that it had to be closed due to structural problems. The site on Eupener Straße is used today by the Aachen University of Applied Sciences .

In April 2011, Philips announced that it would bring the television division into a joint venture with Chinese TPV Technology , in which Philips would hold a 30% stake and TPV Technology a 70% stake; a year later, the joint venture began operations under the name TP Vision . In early 2014, Philips left the television business completely and sold its TP-Vision shares to TPV. TPV thus acquired the right to continue to sell TV sets under the Philips name.

In 2012 and 2013, Philips oriented itself towards small appliances such as mixers, razors and electric toothbrushes and was also successful with a reduced workforce.

In 2013, the company renounced the “Electronics” in its previous name and has been operating under the name Koninklijke Philips NV ever since .

In 2013 an attempt was made to sell the remaining consumer electronics division to the Japanese company Funai Electric for 150 million euros . This deal failed due to breach of contract on the part of Funai. While Philips examined the sale of the division to other interested parties, this area was continued as an independent unit under the name Woox Innovations with headquarters in Hong Kong . In April 2014 Woox Innovations was sold to Gibson Brands .

In 2015, Philips started selling its lighting division, which has since been canceled due to opposition from regulatory authorities. In May 2016, the company went public. The sale was completed at the end of 2017, so that Philips Lighting was no longer a subsidiary of the Dutch group. In March 2018, the now independent lighting company announced that it would operate under the name Signify .

In December 2018, the takeover of the Philips Photonics division to the Trumpf Group was announced.

Subsidiaries and corporate takeovers

Over the years, Philips has repeatedly bought companies (including Magnavox , Marantz , Saeco , Signetics , Mullard , Paradise Systems, GTE Sylvania, VLSI) and also parted ways with acquisitions or parts of companies.

In Germany, Philips has had production facilities in Aachen (since 1934), initially for radios in Jägerstrasse, and since the war in Rothe Erde a plant for the production of light sources , which today manufactures low-voltage halogen lamps and automotive lamps. Since 1963 this has had its own glassworks called Granus . This glassworks was soon converted to the production of television glass. The picture tube factory built on the same site was supplied with this television glass. The glass and picture tube activities were brought into a joint venture with the Korean LG group in 2000 (LG. Philips Displays). Due to the sharp decline in the market for picture tube televisions, LG. Philips Displays then closed the picture tube factory in 2004 and filed for bankruptcy for the glass factory in January 2006.

In the early 1960s, the German Philips Group took over the Körting & Mathiesen GmbH luminaire factory in Limburg an der Lahn and in 1969 took over the majority of the capital in Siemag Feinmechanische Werke GmbH in Eiserfeld / Sieg (today: the district of Siegen). At the same time, the company was renamed Philips Electrologica GmbH . The collaboration between the Philips Group and the Eiserfeld factory began in 1965 with the acquisition of a 40 percent equity stake. Magnetic account computers, accounting machines, electronic desk calculators and dictation machines were manufactured. Later, personal computers, including the much-acclaimed “Yes” system, and dot matrix printers were manufactured in Eiserfeld for the Philips communications industry (PKI) . In 1992 Philips closed the Eiserfeld site completely. Printer production was outsourced to a management buy-out under the name PSi.

From 1984 to 1998 Grundig AG was also part of the Philips Group. 1979 took over Philips at Felten & Guilleaume Carlswerk AG in Cologne the majority, changed its name in 1982 most of the Company's Philips Kommunikations Industrie AG (PKI) to the energy technology sector brought as Felten & Guilleaume Energietechnik AG on the stock exchange and sold in 1993, the glass fiber division of PKI to Nokia .

Science funding

From 1968, Philips organized a Europe-wide science competition, the European Philips Contest for Young Scientists and Inventors, for schoolchildren and young students. In 1989 the organization of the competition was taken over by the European Union and renamed the European Union Contest for Young Scientists .

Royal Philips and the German Interdisciplinary Association for Intensive and Emergency Medicine eV (DIVI) have been awarding the joint research award for Delirium Management since 2014. It is aimed at young scientists whose work deals with non-pharmacological therapeutic management, early detection (screening) or the prevention of delirium.

Adolf Eichmann in Jerusalem with Philips headphones without a logo

The Philips logo, first used in 1930, is currently used as a supplement to the word mark on promotional material and on Philips printouts. It has its origins in the packaging designs for a Miniwatt radio tube and the Philigraph sound recording device , which were first provided with the typical waves and stars in 1926. These symbols should symbolize the radio waves and the ethereal evening sky. In 1930, the four stars in the logo were arranged in a circle around the three waves for the first time.

In pictures of the Eichmann trial in Jerusalem in 1961 , the defendant Adolf Eichmann , who was sentenced to death for his significant involvement in the organization of the Holocaust , was seen wearing Philips headphones. The Dutch writer Harry Mulisch writes in his report book De zaak 40/61 (1962, German: Strafsache 40/6 , 1963) about his observation of the process that Philips had the lettering removed from the ear cups , thus damaging the image in the Arabic Avoid market.

The Philips logo is also on the administration building. Its short version, the word mark with the lettering "PHILIPS" in the Gill Sans font , was carefully typographically revised around 2008.

In September 2004, Philips integrated the brand promise “sense and simplicity” (German: “Sinn und simplicity”) into its logo and added the line “sense and simplicity” to the PHILIPS lettering.

On November 13, 2013, the brand was completely repositioned. The previous tagline “Sense and Simplicity” was abandoned as too complex after several years of consumer tests and replaced by the new brandline “innovation + you”. The plus is represented in the form of the stars known from the "Philips shield", which symbolize a flash of light. The brand line is placed in English in most countries. There is a representation in the national language in Arabic, Chinese, Spanish, French, Portuguese, Turkish and Russian.

On the same date, the brand label was renewed. The previously filigree contours have been emphasized more clearly, the waves have been reduced from three to two, and the upper edge has been given a slight outward curvature, which symbolizes future orientation while at the same time preserving tradition.

The share is listed on the Amsterdam Stock Exchange and listed in the AEX index . Around 100% of the shares are in free float.


In 2006 Philips received the negative Big Brother Award for the implementation of technical processes and key data in the Orange Book standard in order to leave a unique serial number on burned CDs during the burn process.
