Context: Toshiba was founded in 1938 as Tokyo Shibaura Electric K.K. through the merger of Shibaura Seisaku-sho (founded in 1875) and Tokyo Denki (founded in 1890). The company name was officially changed to Toshiba Corporation in 1978. Toshiba made a large number of corporate acquisitions during its history, including of Semp in 1977, of Westinghouse Electric LLC, a nuclear energy company in 2006, of Landis+Gyr in 2011, and of IBM's point-of-sale business in 2012., DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions., Koninklijke Philips N.V. (Royal Philips, commonly known as Philips) is a Dutch technology company headquartered in Amsterdam with primary divisions focused in the areas of electronics, healthcare and lighting. It was founded in Eindhoven in 1891, by Gerard Philips and his father Frederik. It is one of the largest electronics companies in the world and employs around 105,000 people across more than 60 countries., Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan., In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc which encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (often aluminium ) on one of its flat surfaces. The encoding material sits atop a thicker substrate (usually polycarbonate) which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive which spins the disc at speeds of about 200 to 4,000 RPM or more, depending on the drive type, disc format, and the distance of the read head from the center of the disc (inner tracks are read at a higher disc speed). Most optical discs exhibit a characteristic iridescence as a result of the diffraction grating formed by its grooves. This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself. Unlike the 3-inch floppy disk, most optical discs do not have an integrated protective casing and are therefore susceptible to data transfer problems due to scratches, fingerprints, and other environmental problems., Nunsploitation is a subgenre of exploitation film which had its peak in Europe in the 1970s. These films typically involve Christian nuns living in convents during the Middle Ages. The main conflict of the story is usually of a religious or sexual nature, such as religious oppression or sexual suppression due to living in celibacy. The Inquisition is another common theme. These films, although often seen as pure exploitation films, often contain criticism against religion in general and the Catholic Church in particular. Indeed, some protagonist dialogue voiced feminist consciousness and rejection of their subordinated social role. Many of these films were made in countries where the Catholic Church is influential, such as Italy and Spain. One atypical example of the genre, "Killer Nun" ("Suor Omicidi"), was set in then present-day Italy (1978)., Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its four operating components  electronics (video games, network services and medical business), motion pictures, music and financial services. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation, Sony Pictures Entertainment, Sony Interactive Entertainment, Sony Music Entertainment, Sony Mobile (formerly Sony Ericsson) and Sony Financial. Sony is among the Semiconductor sales leaders by year and as of 2013, the fourth-largest television manufacturer in the world, after Samsung Electronics, LG Electronics and TCL., Killer Nun (also known as Suor Omicidi, or Deadly Habits) is a 1979 Italian nunsploitation film directed and co-written by Giulio Berruti and co-written by Alberto Tarallo. The film was originally banned in Britain as a 'video nasty' and released with cuts in 1993, but was finally released uncut on DVD in the UK during 2006, after changes in British censorship policy., Killer Nun ( also known as Suor Omicidi , or Deadly Habits ) is a 1978 Italian nunsploitation film directed and co-written by Giulio Berruti and co-written by Alberto Tarallo .
