The classic red 2x4 Lego brick. Note the protruding interlocking "stud" mechanism atop the brick.
Lego is a line of building toys manufactured by the Lego
Group, a privately held company based in Denmark.
Its flagship product, commonly referred to as Lego bricks, consists of colorful interlocking plastic bricks and an
accompanying array of gears, minifigures (also called minifigs by Lego fans), and various
other parts. There are other Lego pieces which can be assembled and connected in many ways, such as cars, trucks, planes, trains,
buildings, castles, sculptures, ships, spaceships, and even working robots.
Early history
-
- See also: Lego timeline
The Lego Group had a very humble beginning in the workshop of Ole Kirk
Christiansen, a carpenter from Billund, Denmark. Christiansen began creating wooden toys
in 1932, and began calling itself "Lego" two years later in 1934. The company expanded to producing plastic toys in 1947. In
1949, Lego began producing the now-famous interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based
largely on the design of Kiddicraft Self-Locking Bricks, which were released in the UK in
1947. The first Lego bricks, manufactured from cellulose acetate, were developed in
the spirit of traditional wooden blocks that could be stacked upon one another; however, these plastic bricks could be "locked"
together. They had several round "studs" on top, and a hollow rectangular bottom. The blocks snapped together, but not so tightly
that they could not be pulled apart.
The company name Lego was coined by Christiansen from the Danish phrase leg
godt, which means "play well". The name could also be interpreted as "I put together" or "I assemble" in Latin, though this would be a somewhat forced application of the general sense "I collect; I gather; I learn"; the
word is most used in the derived sense, "I read". The cognate Greek verb "λέγω" also means "gather, pick up", but this can include constructing a stone wall.[1]
The Lego motto, det bedste er ikke for godt, is Danish for "The best isn't good enough". This motto was created by Ole
Kirk to encourage his employees never to skimp on quality, a value he believed in strongly. The motto is still used within the
company.
The use of plastic for toy manufacture was not highly regarded by retailers and consumers of the time. Many of the Lego
Group's shipments were returned, following poor sales; it was thought that plastic toys could never replace wooden ones.
By 1954, Christiansen's son, Godtfred Kirk Christiansen, had become the
junior managing director of the Lego Group. It was his conversation with an overseas buyer that struck the idea of a toy system.
Godtfred saw the immense potential in Lego bricks to become a system for creative play, but the bricks still had some problems
from a technical standpoint: their "locking" ability was limited, and they were not very versatile. It was not until 1958 that
the modern-day brick design was developed, and it took another five years to find exactly the right material for it.
Design and manufacture
Lego pieces of all varieties have been, first and foremost, part of a universal system. Despite tremendous variation in the
design and purpose of individual pieces over the years, each remains compatible in some way with existing pieces. Lego bricks
from 1963 still interlock with those made in 2007, and Lego sets for young children are compatible with those made for teenagers,
and those who are mature enough.
Bricks, beams, axles, mini figures, and all other elements in the Lego system are manufactured to an exacting degree of
tolerance. When snapped together, pieces must have just the right amount of
"clutch power"; they must stay together until pulled apart. They cannot be too easy to pull apart, or the resulting constructions
would be unstable; they also cannot be too difficult to pull apart, since the disassembly of one creation in order to build
another is part of the Lego appeal. In order for pieces to have just the right "clutch power", Lego elements are manufactured
within a tolerance of 2 µm.[2]
Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene, or ABS. Precision-machined, small-capacity molds are
used, and human inspectors check the output of the molds, to eliminate significant variations in color or thickness. Worn-out
molds are encased in the foundations of buildings to prevent their falling into competitors' hands. According to the Lego Group,
about eighteen bricks out of every million fail to meet the standard required.[2]
Manufacturing of Lego bricks occurs at a number of locations around the world. Molding is done at one of two plants in Denmark
and Czech Republic. Brick decorations and packaging is done at plants in Denmark, United
States, Mexico and the Czech Republic. Annual production of Lego bricks averages
approximately 20 billion (2 × 1010) per year, or about 600 pieces per second.
In 2006, Lego Group announced a restructuring of the current production setup including the outsourcing of some of the
production work to Flextronics, a Singaporean electronics
company. [3] Lego Group plans
to close the production facility in Enfield, Connecticut and outsource this work to
the Flextronics factory in Mexico.[3][4] Flextronics will also oversee the factory in Kladno,
Czech Republic. The Czech facilities would also be expanded due to the planned closing of the Swiss factory in Baar, which mostly manufactured TECHNIC parts.[4]
Today
Since it began producing plastic bricks, the Lego Group has released thousands of play sets themed around space, robots,
pirates, vikings, ninjas, medieval castles, dinosaurs, cities, suburbia, holiday locations,
wild west, the Arctic, airports, miners, community,
boats, racing cars, trains, motorized Lego models, Star Wars, Jurassic Park III, Harry Potter,
Spider-Man, Batman,
SpongeBob SquarePants, Avatar: The Last Airbender, Ferrari and much
more. New elements are often released along with new sets. There are also Lego sets designed to appeal to young girls such as the
Clikits line which consists of small interlocking parts that are meant to encourage creativity
and arts and crafts, much like regular Lego bricks. Clikit pieces can interlock with regular Lego bricks as decorative
elements.
Recently, Lego has expanded to encompass accessory motors, gears, lights, sensors, and cameras designed to be used with Lego
components. There are even special bricks, like the Lego RCX that can be programmed with
a PC to perform very complicated and useful tasks. These programmable bricks are sold
under the name Lego Mindstorms.
In 2006 a new Lego Mindstorms kit called Mindstorms NXT was released. It is more
advanced than the RCX, has a bigger screen than the RCX, and has a new array of sensors. They include touch, sound, light, and a
new ultrasonic sensor technology. There is also a Bluetooth compatible hookup that can send and receive messages from one's cellphone and other Bluetooth compatible devices. The RCX was only
compatible with Windows, but NXT is compatible with both Windows and Mac OS.
There are several robotics competitions which use Lego bricks and the RCX. The earliest, and likely the largest, is
Botball, a national U.S. middle- and high-school competition stemming from the MIT 6.270 Lego robotics tournament. A related competition is
FIRST Lego League for elementary and middle
schools. The international RoboCup Junior autonomous soccer competition involves extensive use of Lego Mindstorms
equipment which is often pushed to its extreme limits.
Bionicle is a line of toys by the Lego Group that is marketed towards those in the 7–16-year-old age range. The line was launched in January
2001 in Europe and June/July 2001 in the United States.
The Bionicle idea originated from the earlier toy lines Slizers (also known as
Throwbots) and Roboriders. Both of these lines had similar throwing disks and characters based on classical elements. The sets in the Bionicle line have increased in size and flexibility through the
years.
Lego Group operates four Legoland amusement parks,
three in Europe and one in California. On
July 13, 2005, the control of 70% of the Legoland parks was sold
for $460 million to the Blackstone Group of New York while the remaining 30% is still
held by the Lego Group. There are also several Lego Brand retail stores, including at Downtown
Disney in both the Disneyland and Walt Disney World Resorts and in the Mall of America
in Bloomington, Minnesota. As of year end 2005, there are 25 Lego Brand Retail
stores in the USA, a number of stores in Europe, and a franchised Lego store in Abu Dhabi.
Lego has also successfully branched into video games that appeal to a wide age range, with titles like Lego Star Wars: The Video Game, Lego Star Wars II: The Original Trilogy, the upcoming Lego MMORPG, Lego Batman, and Lego
Indiana Jones.

In art
One hobby among enthusiasts is to make short movies or recreations of feature films using Lego bricks. Such movies are called
"Lego movies", "Brickfilms", "Legomations", or "cinema Lego". They usually use
stop motion animation. For example, the Monty Python and the Holy Grail special
edition DVD contained a version of the Camelot musical sequence redone with Lego
minifigures and accessories.
Lego used to sell a line of sets named "LEGO Studios" (now discontinued), which contains a Lego web
cam (repackaged Logitech USB Quickcam Web), software to record video on a computer, black plastic rods which can be used
to manipulate minifigures from off-camera and a minifigure resembling Steven Spielberg.
Because of the low quality of the camera and software most Brickfilmers do not use it.
Lego bricks have been used to recreate many music videos. Examples include a re-dubbed version of the song "Dragostea Din Tei" by O-Zone, and "Feuer frei!" by Rammstein.
Another notable example is the award-winning music video for the song "Fell in Love with a Girl" by the White Stripes.
Director Michel Gondry filmed a live version of the video, digitized the result and then recreated it entirely with Lego bricks.
Artists have also used Lego sets with one of the more notorious examples being Polish artist Zbigniew Libera's "Lego Concentration Camp", a collection of mocked-up concentration camp-themed
Lego sets.
The Little Artists have created an entire Modern
Art collection in a Lego Gallery. 'Art Craziest Nation' was shown at the Walker Art
Gallery in Liverpool, UK.
Several webcomics are illustrated with Lego, notably Legostar Galactica and
Irregular Webcomic!.
Mr. Amperduke is a silent graphic novel featuring Lego type creatures which originally
appeared in the British comic Judge Dredd Megazine
The Reverend Brendan Powell Smith has created an illustrated bible using Lego bricks, called the Brick Testament.
Nathan Sawaya is a professional Lego artist who currently has a museum show of Lego
sculptures and Mosaics touring the US:The
Art of the Brick
Serious Play
-
Since around 2000, the Lego Group has been promoting Lego Serious Play, a form of business consultancy fostering creative
thinking, in which team members build metaphors of their organisational identities and experiences using Lego bricks.
Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring
possibilities in a serious form of play.
Trademark
A message displayed to visitors of
http://www.legos.com
protesting the dilution of the Lego trademark
The LEGO Group's name has become so synonymous with its flagship toy that many refer to
the bricks themselves (collectively) as "Lego" or "Legos" (the latter term being common in US
English, but rarely used in British English), although the Lego Group considers
such uses to be trademark dilution. Lego catalogues in the 1970s and 1980s contained
a note that read:
"The word LEGO® is a brand name and is very special to all of us in the LEGO Group Companies. We would sincerely like your
help in keeping it special. Please always refer to our bricks as 'LEGO Bricks or Toys' and not 'LEGOS.' By doing so, you will be
helping to protect and preserve a brand of which we are very proud and that stands for quality the world over. Thank you! Susan
Williams, Consumer Services."
The official Lego website is http://www.lego.com. For
many years, visitors to http://www.legos.com (also
registered to the Lego Group) have received notices similar to the one pictured, and were intentionally redirected to the
official website, to further protect the brand.
LEGO is officially written in all uppercase letters. The company asserts that
to protect its brand name, the word Lego must always be used as an adjective, as in "LEGO set", "LEGO products", "LEGO universe",
and so forth. Nevertheless, such corporate admonitions are frequently ignored and the word Lego is commonly used not only
as a noun to refer to Lego bricks, but also as a generic term referring to any kind of interlocking toy brick.

- Lego Group produces over 306 million miniature tires each year - more than any other tire
manufacturer in the world.[2]
- Six 2x4 Lego bricks of the same color can be put together in 915,103,765 ways, and just three bricks of the same color offer
1,560 combinations. The figure of 102,981,500 is often given for six pieces, but it is incorrect. The number 102,981,504 (four
more than that figure) is the number of six-piece towers (of a height of six).[5][6][7]
- On average, everyone in the world has 62 Lego bricks each.[2]
- Only one percent of the plastic waste in Lego factories goes unrecycled.[8]
