Do it yourself (DIY) is the method of building, modifying, or repairing things without the direct aid of experts or professionals. Academic research describes DIY as behaviors where "individuals engage raw and semi-raw materials and component parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g. landscaping)". DIY behavior can be triggered by various motivations previously categorized as marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity enhancement (craftsmanship, empowerment, community seeking, uniqueness).
The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in standard English) by the 1950s, in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.
Subsequently, the term DIY has taken on a broader meaning that covers a wide range of skill sets. DIY is associated with the international alternative rock, punk rock, and indie rock music scenes; indymedia networks, pirate radio stations, and the zine community. In this context, DIY is related to the Arts and Crafts movement, in that it offers an alternative to modern consumer culture's emphasis on relying on others to satisfy needs. The abbreviation DIY is also widely used in the military as a way to teach commanders or other types of units to take responsibility, so that they'd be able to do things themselves just as a preparation for their own future.
Italian archaeologists unearthed the ruins of a 6th-century BC Greek structure in southern Italy that came with detailed assembly instructions and is being called an "ancient IKEA building". The structure was a temple-like building discovered at Torre Satriano, near the southern city of Potenza, in Basilicata, a region where local people mingled with Greeks who settled along the southern coast known as Magna Graecia and in Sicily from the 8th century BC onwards. Professor Christopher Smith, director of the British School at Rome, said that the discovery was "the clearest example yet found of mason's marks of the time. It looks as if someone was instructing others how to mass-produce components and put them together in this way". Much like the instruction booklets, various sections of the luxury building were inscribed with coded symbols showing how the pieces slotted together. The characteristics of these inscriptions indicate they date back to around the 6th century BC, which tallies with the architectural evidence suggested by the decoration. The building was built by Greek artisans coming from the Spartan colony of Taranto in Apulia.
