Hacker culture is an idea derived from a community of enthusiast computer programmers and systems designers in the 1960s around the Massachusetts Institute of Technology's (MIT's) Tech Model Railroad Club (TMRC)[17] and the MIT Artificial Intelligence Laboratory.[18] The concept expanded to the hobbyist home computing community, focusing on hardware in the late 1970s (e.g. the Homebrew Computer Club)[19] and on software (video games,[20] software cracking, the demoscene) in the 1980s/1990s. Later, this would go on to encompass many new definitions such as art, and life hacking.
