Plagiarism applies to the "real world" (that is, the "non-academic" realm), as well! In fact, published (and in many cases, even "non-published") material that can be referred to as "plagiarized" (e.g. paraphrased ideas, or copied, writing, or translated material, or PowerPoint presentations, business ideas, lectures, etc.). that is published, or presented publically or to a widestream audience— without giving proper credit to source(s) is, in fact, "plagiarism" — and is called "plagiarism" as well.
In such cases of plagiarism, severe consequences may result, including job demotions/terminations, civil actions (law suits), monetary restitution and public apologies—even companies going bankrupt; as well as reputations destroyed.
Furthermore, many colleges have academic integrity policies that specifically state that plagiarism still occurs in cases of drafts of work—even when not final written essays—are required to be submitted to teachers/professors/T.A.'s. Furthermore, plagiarism is not limited to written essays—but also other types of assignments (e.g. oral reports for any class, communication/lecture assignments, any data used/obtains, information on spreadsheets (e.g. accounting/business classes, any artwork, computer science codes).
