context_page_description: Sharp Corporation is a major Japanese multinational corporation that designs and manufactures electronic products, headquartered in Sakai-ku, Sakai, Osaka Prefecture. Since 2016 it has been majority owned by the Taiwan-based Foxconn Group. Sharp employs more than 50,000 people worldwide. The company was founded in September 1912 in Tokyo and takes its name from one of its founder's first inventions, the Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa in 1915.
context_section_description: In 1953, Hayakawa Electric started producing the first Japan-made TV sets (the "Sharp TV3-14T").
  In 1964, the company developed the world's first transistor calculator (the Sharp CS-10A), which was priced at JP¥535,000 (US$1,400). It took Sharp several years to develop the product as they had no experience in making computing devices at the time.  Two years later, in 1966, Sharp introduced its first IC calculator using 145 Mitsubishi Electric-made bipolar ICs, priced at JP¥350,000 (about US$1000). Its first LSI calculator was introduced in 1969. This was the first pocketable calculator priced at less than JP¥100,000 (less than US$300), and turned out to be a popular item. 
  Also in the same era the company introduced the first microwave oven with a turntable between 1964 and 1966. The company was renamed Sharp Corporation in 1970.
  Sharp produced the first LCD calculator in 1973. Sharp had a working relationship with Nintendo during the 1980s, and was granted licensing rights for the manufacture and development of the C1 NES TV (1983, later released in North America as the Sharp Nintendo Television), the Twin Famicom (1986), the Sharp Famicom Titler (1989), and the SF-1 SNES TV (1990). All of these units are considered collectors items on the secondary market. One of the company's main inventors of LCD calculators was Tadashi Sasaki.
  Sharp introduced low-cost microwave ovens affordable for residential use in the late 1970s.
  Sharp ventured into the high end stereo market in 1976 with the introduction of high end receivers, amplifiers, speakers, turntables and cassette players.  The Optonica line as it was called, consisted of high quality and technically advanced components, that was expanded in 1979, to cover a broader selection of high end equipment. During this run, Sharp introduced digital technology to some of the Optonica products, along with the traditional analogue products, and offered a complete selection of models ranging from low power high end receivers to very powerful models.  The line was again changed, in 1981, and moved mainly into digital high end, complete stereo systems with advanced technological features setting the trend towards the digital age.  The line was discontinued after 1981, but the Optonica line was again re-introduced in the late 1980s for a high end line of television receivers and higher quality mass market audio products such as VCR's, surround sound receivers, CD cassette boom boxes, and portable cassette players.
