It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the world's first mass-produced digital watches.
History
Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio (
樫尾忠雄 1917–1993), an
engineer specializing in fabrication technology.
Kashio's first major product was the yubiwa pipe, a finger ring that would hold a
cigarette
A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opp ...
, allowing the wearer to
smoke the cigarette down to its nub while also leaving the wearer's hands free.
Japan was
impoverished immediately following
World War II, so cigarettes were valuable, and the invention was a success.

, Tokyo in 1949, Kashio and his younger brothers (Toshio, Kazuo, and Yukio) used their profits from the yubiwa pipe to develop their calculators. Most of the calculators at that time worked using gears and could be operated by hand using a crank or using a motor (see
adding machine).
Toshio possessed some knowledge of electronics and set out to make a calculator using

s. After dozens of prototypes were tested, the desk-sized calculator was finished in 1954 and was Japan's first electro-mechanical calculator. One of the central and more important innovations of the calculator was its adoption of the 10-key number pad; at that time other calculators were using a "full keypad", which meant that each place in the number (1s, 10s, 100s, etc ...) had nine keys. Another distinguishing innovation was the use of a single display window instead of the three display windows (one for each argument and one for the answer) used in other calculators.
Casio Computer Co., Ltd. was formed in June 1957.
That year, Casio released the Model 14-A, sold for 485,000
yen, the world's first all-electric compact calculator, which was based on relay technology.
In 1974, Casio released their first digital wristwatch, called the
CASIOTRON. It was the first wristwatch in the world to include an automatic calender function. In 1977, they released a
retro-futuristic wristwatch, called the
F100. The watch was one of the first wristwatches in the world to be made primarily out of
resin, making it very light compared to other companies' heavy metal-made watches and enabling future Casio watches to enter

more easily. In 1989, Casio released another important wristwatch; the
F-91W, the most sold wristwatch in the worldwith an annual producion of 3 million units.
In the 1980s, Casio's budget electronic instruments and its line of affordable home electronic
musical keyboard instruments became popular. The company also became well known for the wide variety and innovation of its
wristwatches. It was one of the earliest manufacturers of
quartz watches, both digital and analog. It also began selling
calculator watches during this time. Casio also introduced one of the first watches that could display the time in many different
time zones of the world and with features like recording temperature, atmospheric-pressure and altitude. In the later years, Casio's wristwatches were fitted with receivers to synchronise with radio towers around the world and
