The hacker ethic is a branch of philosophy, originating from hacker culture and pertaining to the idea that intellectual goods, like information and data, cannot be owned by an individual, hence sharing them with others is an ethical imperative. It shares several traits with concepts such as freedom of information, and political philosophies such as anti-authoritarianism, socialism, liberalism, anarchism, and libertarianism.

The hacker culture is a subculture of individuals who enjoy—often in collective effort—the intellectual challenge of creatively overcoming the limitations of software systems or electronic hardware, to achieve novel and clever outcomes. The act of engaging in activities in a spirit of playfulness and exploration is termed hacking. However, the defining characteristic of a hacker is not the activities performed themselves, but how it is done and whether it is exciting and meaningful. Activities of playful cleverness can be said to have "hack value" and therefore the term "hacks" came about, with early examples including pranks at MIT done by students to demonstrate their technical aptitude and cleverness. The hacker culture originally emerged in academia in the 1960s around the Massachusetts Institute of Technology (MIT)'s Tech Model Railroad Club (TMRC) and MIT Artificial Intelligence Laboratory. Hacking originally involved entering restricted areas in a clever way without causing any major damage. Some famous hacks at the Massachusetts Institute of Technology were placing of a campus police cruiser on the roof of the Great Dome and converting the Great Dome into R2-D2.
