In marketing terminology, a killer feature is any attribute of a product that proves so useful as to become the main attraction of the product. Examples include spreadsheets as a feature of the PC, or pornography as a feature of the Internet.
Analogous to killer application, which specifically refers to software as a killer feature of its compatible hardware (meaning that the software sells the hardware), the term killer feature often more specifically refers to software features that sell the software.
