What's the difference between i.e. and e.g.?
1791, "condition of being public," from French publicité (1690s), from Medieval Latin publicitatem (nominative publicitas), from Latin publicus (see public (adj.)). Sense of "a making (something) known, an exposure to the public" is from 1826, shading by c.1900 into "advertising, business of promotion." Publicity stunt first recorded 1908.
